  "description": "The Coquille River system is an unregulated system that encompasses 2,745 square kilometers of southwestern \nOregon and flows into the Pacific Ocean near the town of Bandon, Oregon. Beginning in the Rogue River-Siskiyou National Forest, \nthe South Fork Coquille River gains the Middle Fork Coquille River (drainage area 798 square kilometers) and shortly thereafter the \nNorth Fork Coquille River (749 square kilometers). In cooperation with the U.S. Army Corps of Engineers, the U.S. Geological Survey \ncompleted a reconnaissance-level assessment of channel condition and bed-material transport relevant to the permitting of in-stream \ngravel extraction along the the South Fork Coquille River from river kilometer (RKM) 115.4 near its confluence with Upper Land Creek \nto RKM 58.5 at its confluence with the North Fork Coquille River, the mainstem Coquille River from RKM 58.5 at the confluence of the \nSouth and North Forks of the Coquille River to its mouth, the Middle Fork Coquille River from RKM 15.4 to its confluence with the \nSouth Fork Coquille River, and the North Fork Coquille River from RKM 14.6 to its confluence with the South Fork Coquille River. To \nsupport these analyses, digital channel maps were produced to depict channel and floodplain conditions in the Coquille River basin \nfrom different time periods. GIS layers defining the wetted channel and bar features and channel centerline of Hunter Creek were \ndeveloped for four time periods: 1939, 1967, 2005, and 2009. For this project, the active channel was defined as area typically \ninundated during annual high flows, and includes the low-flow channel as well as side channels, islands, and channel-flanking gravel \nbars. The wetted channel and bar feature datasets were developed by digitizing from aerial photographs. Aerial photographs from 1939 \nand 1967 were scanned, rectified, and mosaicked for this project (See metadata for each photograph set for more information on the \nrectification process and resolution of each dataset). Digital orthophotographs from 2005 and 2009 are publicly available.",

The source data set is a 100-meter version of Hydrologic \nLandscape Regions of the United States (Wolock, 2003). HLR groups watersheds on the basis of similarities \nin land-surface form, geologic texture, and climate characteristics.\n\t\t\nThe NHDPlus Version 1.1 is an integrated suite of application-ready geospatial datasets that incorporates \nmany of the best features of the National Hydrography Dataset (NHD) and the National Elevation Dataset \n(NED). The NHDPlus includes a stream network (based on the 1:100,00-scale NHD), improved networking, \nnaming, and value-added attributes (VAAs). NHDPlus also includes elevation-derived catchments \n(drainage areas) produced using a drainage enforcement technique first widely used in New England, \nand thus referred to as \"the New England Method.\" This technique involves \"burning in\" the 1:100,000-scale \nNHD and when available building \"walls\" using the National Watershed Boundary Dataset (WBD). The \nresulting modified digital elevation model (HydroDEM) is used to produce hydrologic derivatives that agree \nwith the NHD and WBD. Over the past two years, an interdisciplinary team from the U.S. Geological Survey \n(USGS), and the U.S. Environmental Protection Agency (USEPA), and contractors, found that this method \nproduces the best quality NHD catchments using an automated process (USEPA, 2007). The NHDPlus \ndataset is organized by 18 Production Units that cover the conterminous United States.\n\t\t\nThe NHDPlus version 1.1 data are grouped by the U.S. Geologic Survey's Major River Basins (MRBs, \nCrawford and others, 2006). MRB1, covering the New England and Mid-Atlantic River basins, contains \nNHDPlus Production Units 1 and 2. MRB2, covering the South Atlantic-Gulf and Tennessee River basins, \ncontains NHDPlus Production Units 3 and 6. MRB3, covering the Great Lakes, Ohio, Upper Mississippi, \nand Souris-Red-Rainy River basins, contains NHDPlus Production Units 4, 5, 7 and 9. MRB4, covering \nthe Missouri River basins, contains NHDPlus Production Units 10-lower and 10-upper.

The streamflow measurements\nwere made to obtain data on ground-water/surface-water interaction. Flow\nwas observed visually to be zero, was measured, or was estimated at\n55 sites. Tributaries were followed upstream until the first road\ncrossing where zero flow was encountered. For selected streams, points\nof zero flow upstream of the first zero flow site also were checked.\n\nStreamflow gain or loss for each stream reach was calculated by\nsubtracting the streamflow values measured at the upstream end of\nthe reach and values for contributing tributaries from the\ndownstream value. The data obtained reflected base-flow conditions\nsuitable for estimating streamflow gains and losses for\nstream reaches between sites.\n\nThis digital data set was created by manually splitting the lines\nfrom a 1:250,000 hydrography data set (Soenksen and others, 1999) at\nevery streamflow-measurement site. Each set of stream segments between\nmeasurement sites was assigned a unique reach number.",

+ "description": "This data set represents the area of Hydrologic Landscape Regions (HLR) compiled for every catchment \nof NHDPlus for the conterminous United States. The source data set is a 100-meter version of Hydrologic \nLandscape Regions of the United States (Wolock, 2003). HLR groups watersheds on the basis of similarities \nin land-surface form, geologic texture, and climate characteristics.\n\t\t\nThe NHDPlus Version 1.1 is an integrated suite of application-ready geospatial datasets that incorporates \nmany of the best features of the National Hydrography Dataset (NHD) and the National Elevation Dataset \n(NED). The NHDPlus includes a stream network (based on the 1:100,00-scale NHD), improved networking, \nnaming, and value-added attributes (VAAs). NHDPlus also includes elevation-derived catchments \n(drainage areas) produced using a drainage enforcement technique first widely used in New England, \nand thus referred to as \"the New England Method.\" This technique involves \"burning in\" the 1:100,000-scale \nNHD and when available building \"walls\" using the National Watershed Boundary Dataset (WBD). The \nresulting modified digital elevation model (HydroDEM) is used to produce hydrologic derivatives that agree \nwith the NHD and WBD. Over the past two years, an interdisciplinary team from the U.S. Geological Survey \n(USGS), and the U.S. Environmental Protection Agency (USEPA), and contractors, found that this method \nproduces the best quality NHD catchments using an automated process (USEPA, 2007). The NHDPlus \ndataset is organized by 18 Production Units that cover the conterminous United States.\n\t\t\nThe NHDPlus version 1.1 data are grouped by the U.S. Geologic Survey's Major River Basins (MRBs, \nCrawford and others, 2006). MRB1, covering the New England and Mid-Atlantic River basins, contains \nNHDPlus Production Units 1 and 2. MRB2, covering the South Atlantic-Gulf and Tennessee River basins, \ncontains NHDPlus Production Units 3 and 6. MRB3, covering the Great Lakes, Ohio, Upper Mississippi, \nand Souris-Red-Rainy River basins, contains NHDPlus Production Units 4, 5, 7 and 9. MRB4, covering \nthe Missouri River basins, contains NHDPlus Production Units 10-lower and 10-upper. MRB5, covering \nthe Lower Mississippi, Arkansas-White-Red, and Texas-Gulf River basins, contains NHDPlus Production \nUnits 8, 11 and 12. MRB6, covering the Rio Grande, Colorado and Great Basin River basins, contains \nNHDPlus Production Units 13, 14, 15 and 16. MRB7, covering the Pacific Northwest River basins, \ncontains NHDPlus Production Unit 17. MRB8, covering California River basins, contains NHDPlus \nProduction Unit 18.",

The surficial geology, inferred ice-marginal positions, and distribution of stratified-drift \naquifers were mapped from existing data. Ice-marginal positions, which represent pauses in the \nretreat of glacial ice from the region, favored the accumulation of coarse-grained deposits whereas \nmore steady or rapid ice retreat between these positions favored deposition of fine-grained lacustrine \ndeposits with limited coarse-grained deposits at depth. Unconfined aquifers with thick saturated \ncoarse-grained deposits are the most favorable settings for water-resource development, and three \nseveral-mile-long sections of valley were identified (mostly in Broome County) as potentially favorable: \n(1) the southernmost valley section, which extends from the New YorkPennsylvania border to about \n1 mile north of South Windsor, (2) the valley section that rounds the west side of the umlaufberg \n(an isolated bedrock hill within a valley) north of Windsor, and (3) the eastwest valley section at the \nBroome County Chenango County border from Nineveh to East of Bettsburg (including the lower reach \nof the Cornell Brook valley). Fine-grained lacustrine deposits form extensive confining units between \nthe unconfined areas, and the water-resource potential of confined aquifers is largely untested.Recharge,\nor replenishment, of these aquifers is dependent not only on infiltration of precipitation directly on \nunconfined aquifers, but perhaps more so from precipitation that falls in adjacent upland areas. \nSurface runoff and shallow groundwater from the valley walls flow downslope and recharge valley \naquifers. Tributary streams that drain upland areas lose flow as they enter main valleys on permeable \nalluvial fans. This infiltrating water also recharges valley aquifers.Current (2012) use of water resources \nin the area is primarily through domestic wells, most of which are completedin fractured bedrock in \nupland areas. A few villages in the Susquehanna River valley have supply wells that draw water from \nbeneath alluvial fans and near the Susquehanna River, which is a large potential source of water from \ninduced infiltration.",

+ },
+ "description": "The hydrogeology of the valley-fill aquifer system along a 32-mile reach of the Susquehanna River \nvalley and adjacent areas was evaluated in eastern Broome and southeastern Chenango Counties, \nNew York. The surficial geology, inferred ice-marginal positions, and distribution of stratified-drift \naquifers were mapped from existing data. Ice-marginal positions, which represent pauses in the \nretreat of glacial ice from the region, favored the accumulation of coarse-grained deposits whereas \nmore steady or rapid ice retreat between these positions favored deposition of fine-grained lacustrine \ndeposits with limited coarse-grained deposits at depth. Unconfined aquifers with thick saturated \ncoarse-grained deposits are the most favorable settings for water-resource development, and three \nseveral-mile-long sections of valley were identified (mostly in Broome County) as potentially favorable: \n(1) the southernmost valley section, which extends from the New YorkPennsylvania border to about \n1 mile north of South Windsor, (2) the valley section that rounds the west side of the umlaufberg \n(an isolated bedrock hill within a valley) north of Windsor, and (3) the eastwest valley section at the \nBroome County Chenango County border from Nineveh to East of Bettsburg (including the lower reach \nof the Cornell Brook valley). Fine-grained lacustrine deposits form extensive confining units between \nthe unconfined areas, and the water-resource potential of confined aquifers is largely untested.Recharge,\nor replenishment, of these aquifers is dependent not only on infiltration of precipitation directly on \nunconfined aquifers, but perhaps more so from precipitation that falls in adjacent upland areas. \nSurface runoff and shallow groundwater from the valley walls flow downslope and recharge valley \naquifers. Tributary streams that drain upland areas lose flow as they enter main valleys on permeable \nalluvial fans. This infiltrating water also recharges valley aquifers.Current (2012) use of water resources \nin the area is primarily through domestic wells, most of which are completedin fractured bedrock in \nupland areas. A few villages in the Susquehanna River valley have supply wells that draw water from \nbeneath alluvial fans and near the Susquehanna River, which is a large potential source of water from \ninduced infiltration.",

Full details\nof the model development are in Nolan and Hitt (2006).\n\nFor inputs to the model, spatial attributes representing 16\nnitrogen loading and transport and attenuation factors were\ncompiled as raster data sets (1-km by 1-km grid cell size) for\nthe conterminous United States (see table 1).\n\n>Table 1.-- Parameters of nonlinear regression model for nitrate in shallow\n> ground water (GWAVA-S) and corresponding input spatial data sets.\n> [kg, kilograms; km2, square kilometers.]\n>\n>Nitrogen Source Factors Data Set Name\n> 1 farm fertilizer (kg/hectare) gwava-s_ffer\n> 2 confined manure (kg/hectare) gwava-s_conf\n> 3 orchards/vineyards (percent) gwava-s_orvi\n> 4 population density (people/km2) gwava-s_popd\n> 5 cropland/pasture/fallow (percent) gwava-s_crpa\n>\n>Transport to Aquifer Factors\n> 6 water input (km2/cm) gwava-s_wtin\n> 7 carbonate rocks (yes/no) gwava-s_crox\n> 8 basalt and volcanic rocks (yes/no) gwava-s_vrox\n> 9 drainage ditch (km2) gwava-s_ddit\n> 10 slope (percent x 1000) gwava-s_slop\n> 11 glacial till (yes/no) gwava-s_gtil\n> 12 clay sediment (percent x 1000) gwava-s_clay\n>\n>Attenuation Factors\n> 13 fresh surface water withdrawal gwava-s_swus\n> for irrigation (megaliters/day)\n> 14 irrigation tailwater recovery (km2) gwava-s_twre\n> 15 histosol soil type (percent) gwava-s_hist\n> 16 wetlands (percent) gwava-s_wetl\n\n\"Farm fertilizer\" is the average annual nitrogen input from\ncommercial fertilizer applied to agricultural lands, 1992-2001, in\nkilograms per hectare.\n\n\"Confined manure\" is the average annual nitrogen input from\nconfined animal manure, 1992 and 1997, in kilograms per\nhectare.\n\n\"Orchards/vineyards\" is the percent of orchards/vineyards land\ncover classification.\n\n\"Population density\" is 1990 block group population density, in\npeople per square kilometer.\n\n\"Cropland/pasture/fallow\" is the percent of\ncropland/pasture/fallow land cover classifications.\n\n\"Water input\" is the ratio of the total area of irrigated land\nto precipitation, in square kilometers per centimeter.\n\n\"Carbonate rocks\" is the presence or absence of Valley and Ridge\ncarbonate rocks.\n\n\"Basalt and volcanic rocks\" is the presence or absence of basalt\nand volcanic rocks.\n\n\"Drainage ditch\" is the area of National Resources Inventory surface\ndrainage, field ditch conservation practice, in square kilometers.\n\n\"Slope\" is the soil surface slope, in percent times 1000.\n\n\"Glacial till\" is the presence or absence of poorly sorted\nglacial till east of the Rocky Mountains.\n\n\"Clay sediment\" is the amount of clay sediment in the soil, in\npercent times 1000.\n\n\"Fresh surface water withdrawal for irrigation\" is the amount of\nfresh surface water withdrawal for irrigation, in megaliters per day.\n\n\"Irrigation tailwater recovery\" is the area of National\nResources Inventory irrigation system, tailwater recovery\nconservation practice, in square kilometers.\n\n\"Histosol soil type\" is the amount of histosols soil taxonomic\norder, in percent.\n\n\"Wetlands\" is the percent of woody wetlands and emergent\nherbaceous wetlands land cover classifications.\n\nReference cited:\n\nNolan, B.T. and Hitt, K.J., 2006, Vulnerability of shallow\nground water and drinking-water wells to nitrate in the United\nStates: Environmental Science and Technology, vol. 40, no. 24,\npages 7834-7840.",

The source data set represents land use and land cover for the conterminous United States for 2001. The National Land Cover Data Set for 2001 was produced through a cooperative project conducted by the Multi-Resolution Land Characteristics (MRLC) Consortium. The MRLC Consortium is a partnership of Federal agencies (http://www.mrlc.gov), consisting of the U.S. Geological Survey (USGS), the National Oceanic and Atmospheric Administration (NOAA), the U.S. Environmental Protection Agency (USEPA), the U.S. Department of Agriculture (USDA), the U.S. Forest Service (USFS), the National Park Service (NPS), the U.S. Fish and Wildlife Service (USFWS), the Bureau of Land Management (BLM), and the USDA Natural Resources Conservation Service (NRCS).\n\t\t\nThe NHDPlus Version 1.1 is an integrated suite of application-ready geospatial datasets that incorporates many of the best features of the National Hydrography Dataset (NHD) and the National Elevation Dataset (NED). The NHDPlus includes a stream network (based on the 1:100,00-scale NHD), improved networking, naming, and value-added attributes (VAAs). NHDPlus also includes elevation-derived catchments (drainage areas) produced using a drainage enforcement technique first widely used in New England, and thus referred to as \"the New England Method.\" This technique involves \"burning in\" the 1:100,000-scale NHD and when available building \"walls\" using the National Watershed Boundary Dataset (WBD). The resulting modified digital elevation model (HydroDEM) is used to produce hydrologic derivatives that agree with the NHD and WBD. Over the past two years, an interdisciplinary team from the U.S. Geological Survey (USGS), and the U.S. Environmental Protection Agency (USEPA), and contractors, found that this method produces the best quality NHD catchments using an automated process (USEPA, 2007). The NHDPlus dataset is organized by 18 Production Units that cover the conterminous United States.\n\t\t\nThe NHDPlus version 1.1 data are grouped by the U.S. Geologic Survey's Major River Basins (MRBs, Crawford and others, 2006).

Previously, the concept of a \n''capture map'' has been put forward as a means to effectively summarize this relation \nfor decision-making consumption. While capture maps have enjoyed success in the \nenvironmental simulation industry, they are deterministic, ignoring uncertainty in the \nunderlying model. Furthermore, capture maps are not typically calculated in a manner \nthat facilitates analysis of varying combinations of extraction locations and/or reaches. \nThat is, they are typically constructed with focus on a single reach or group of reaches. \nThe former of these limitations is important for conveying risk to decision makers, while \nthe latter is important for decision-making support related to surface-water management, \nwhere future foci may include reaches that were not the focus of the original capture \nanalysis. \n\t\t\nHerein, we use a MODFLOW-NWT groundwater/surface-water model of the lower San \nAntonio River, Texas, USA to demonstrate a technique to estimate risk-based and \nspatially discrete streamflow depletion potential.

+ "description": "A previously developed groundwater flow model (https://doi.org/10.5066/P9051RUT) \nwas slightly modified to estimate the risk-based discrete relation between groundwater \nextraction and surface-water/groundwater exchange. Previously, the concept of a \n''capture map'' has been put forward as a means to effectively summarize this relation \nfor decision-making consumption. While capture maps have enjoyed success in the \nenvironmental simulation industry, they are deterministic, ignoring uncertainty in the \nunderlying model. Furthermore, capture maps are not typically calculated in a manner \nthat facilitates analysis of varying combinations of extraction locations and/or reaches. \nThat is, they are typically constructed with focus on a single reach or group of reaches. \nThe former of these limitations is important for conveying risk to decision makers, while \nthe latter is important for decision-making support related to surface-water management, \nwhere future foci may include reaches that were not the focus of the original capture \nanalysis. \n\t\t\nHerein, we use a MODFLOW-NWT groundwater/surface-water model of the lower San \nAntonio River, Texas, USA to demonstrate a technique to estimate risk-based and \nspatially discrete streamflow depletion potential. This USGS data release contains \nall of the input and output files for the simulations described in the associated journal \narticle (https://doi.org/10.1111/gwat.13080)",

Beginning in the Rogue River-Siskiyou National Forest, \nthe South Fork Coquille River gains the Middle Fork Coquille River (drainage area 798 square kilometers) and shortly thereafter the \nNorth Fork Coquille River (749 square kilometers). In cooperation with the U.S. Army Corps of Engineers, the U.S. Geological Survey \ncompleted a reconnaissance-level assessment of channel condition and bed-material transport relevant to the permitting of in-stream \ngravel extraction along the the South Fork Coquille River from river kilometer (RKM) 115.4 near its confluence with Upper Land Creek \nto RKM 58.5 at its confluence with the North Fork Coquille River, the mainstem Coquille River from RKM 58.5 at the confluence of the \nSouth and North Forks of the Coquille River to its mouth, the Middle Fork Coquille River from RKM 15.4 to its confluence with the \nSouth Fork Coquille River, and the North Fork Coquille River from RKM 14.6 to its confluence with the South Fork Coquille River. To \nsupport these analyses, digital channel maps were produced to depict channel and floodplain conditions in the Coquille River basin \nfrom different time periods. GIS layers defining the wetted channel and bar features and channel centerline of Hunter Creek were \ndeveloped for four time periods: 1939, 1967, 2005, and 2009. For this project, the active channel was defined as area typically \ninundated during annual high flows, and includes the low-flow channel as well as side channels, islands, and channel-flanking gravel \nbars. The wetted channel and bar feature datasets were developed by digitizing from aerial photographs. Aerial photographs from 1939 \nand 1967 were scanned, rectified, and mosaicked for this project (See metadata for each photograph set for more information on the \nrectification process and resolution of each dataset).

Currently, \nirrigated acreage is estimated routinely for only a few basins in the study area and these acreages are \ncalculated and reported by township range section, quarter, and quarter-quarter. Satellite imagery from \nthe Landsat Thematic Mapper (TM) platform was used to delineate irrigated acreage for the BARCAS \nstudy area on a field by field basis. Six hundred and forty-three fields were delineated by interpreting \nsatellite data. The water source, irrigation system, crop type, and field activity were identified and \nverified through field reconnaissance. These data were integrated into the geodatabase and analyzed \nto develop reasonably accurate estimates of irrigated acreage for the 2000, 2002, and 2005 growing \nseasons by hydrographic area and sub-area. Estimated average annual potential evapotranspiration \nand average annual precipitation were incorporated into the geodatabase as ancillary data. Irrigated \nacreage in 2005 totaled nearly 32,000 acres ranging from less than 200 acres in Butte, Cave, Jakes, \nLong, and Tippett Valleys to 9,200 acres in Snake Valley. Cave, Irrigated acreage increased about 20 \npercent from 2000 to 2005, with Snake and White River Valleys experiencing the greatest increases. \nThe source for about 80 percent of irrigation water applied during drier years is ground water pumped \nfrom wells. About 80 percent of irrigation water applied in 2005 was through sprinkler systems, and \nabout 20 percent was through flood systems. Fields planted in alfalfa accounted for about 88 percent \nof the irrigated acreage.",

+ "description": "Accurate delineations of irrigated acreage are critical in the development of water-use estimates and in \ndetermining an accurate water budget for the hydrographic basins of the BARCAS study area. Currently, \nirrigated acreage is estimated routinely for only a few basins in the study area and these acreages are \ncalculated and reported by township range section, quarter, and quarter-quarter. Satellite imagery from \nthe Landsat Thematic Mapper (TM) platform was used to delineate irrigated acreage for the BARCAS \nstudy area on a field by field basis. Six hundred and forty-three fields were delineated by interpreting \nsatellite data. The water source, irrigation system, crop type, and field activity were identified and \nverified through field reconnaissance. These data were integrated into the geodatabase and analyzed \nto develop reasonably accurate estimates of irrigated acreage for the 2000, 2002, and 2005 growing \nseasons by hydrographic area and sub-area. Estimated average annual potential evapotranspiration \nand average annual precipitation were incorporated into the geodatabase as ancillary data. Irrigated \nacreage in 2005 totaled nearly 32,000 acres ranging from less than 200 acres in Butte, Cave, Jakes, \nLong, and Tippett Valleys to 9,200 acres in Snake Valley. Cave, Irrigated acreage increased about 20 \npercent from 2000 to 2005, with Snake and White River Valleys experiencing the greatest increases. \nThe source for about 80 percent of irrigation water applied during drier years is ground water pumped \nfrom wells. About 80 percent of irrigation water applied in 2005 was through sprinkler systems, and \nabout 20 percent was through flood systems. Fields planted in alfalfa accounted for about 88 percent \nof the irrigated acreage.",

The geology for Corson \nCounty was based on soil maps prepared by the U.S. Bureau of Indian Affairs (1959) \nand unpublished maps of the U.S. Soil Conservation Service, modified by test drilling \nand field reconnaissance.\n\t\t\nThe following definitions were used for figure 5.\n\t\t\nAlluvium, terrace, outwash, colluvium, eolian deposits, and buried-valley fill-- The small \nscale prevents differentiating these deposits on this map. Alluvium is water-laid material \ndeposited on flood plains and valleys of rivers and streams. Most of the material is clay, \nsilt, and fine sand but there is some coarser material. Terraces are older alluvial deposits \nthat now are above the level of the flood plain because the stream has eroded its valley \ndeeper since deposition of the sediment. \n\nOutwash was deposited in streams and lakes formed by melting glaciers. Maximum \nthickness of alluvium or outwash is less than 120 feet; of terraces, more than 50 feet. \nColluvium is landslide and slumpage detritus, commonly deposited at the foot of the \nsteep slopes. The material usually is fragments of shale, silt, and sand, but may \ninclude gravel or sandstone cobbles from terraces or sandstone beds capping higher \nbenches or buttes. Deposits may exceed 100 feet in thickness. Eolian deposits are \nwindblown material, mostly silt and fine sand, but include some clay and, in some \nareas, much medium sand. Deposits are as much as 20 feet thick, but a thin coating, \nas little as a fraction of an inch thick, overlies most of the area. Buried valley fill is \nmostly glacial stream and outwash deposits but includes some till. The material is \nmostly moderately-sorted gravel, sand, silt, and clay. Maximum thickness locally \nexceeds 300 feet. Quaternary Period.\n\t\t\nGlacial till -- Deposited beneath or at the margins of the continental glaciers. The \nmaterial is a heterogeneous mixture of sizes from clay to boulders. Maximum \nthickness probably is less than 40 feet. Quaternary Period.\n\t\t\nFort Union Formation -- Gray to buff interbedded very fine to medium-grained sandstone, \nsiltstone, claystone, silty clay, and shale; thin carbonaceous or lignitic beds near the \nbase. Contains three widely persistent sandstone beds. Maximum thickness is greater \nthan 400 feet. Tertiary Period.\n\t\t\nHell Creek Formation -- Somber-colored, soft clay shale and buff to gray, weakly-cemented, \ncoarse- to fine-grained sandstone and siltstone. Contains lignitic lenses and thin, black \ncarbonaceous shale beds. Maximum thickness may be greater than 400 feet. Cretaceous \nPeriod.\n\t\t\nFox Hills Formation -- Dark- to light-gray silty and sandy clay, clayey silt, and very fine-grained \nsandstone; overlain, in Corson County, by dark-gray to yellowish-orange, weakly-cemented, very \nfine-grained sandstone. The upper part of the formation is a thinly-bedded sequence of clay, silt, \nand sand, that contains discontinuous beds of silica-cemented very fine-grained sandstone. \nContacts between the Hell Creek and Pierre Shale are gradational. Maximum thickness is about \n400 feet. Cretaceous Period.\n\t\t\nPierre Shale -- Gray to brown, tough, gummy to friable shale, noncalcareous to highly calcareous, \ncontains widely persistent zones of bentonite and of iron manganese or limestone concretions. \nWhere exposed at the surface, the top few feet commonly is weathered. Maximum thickness is \nabout 1,400 feet. Cretaceous Period.",

In cooperation \nwith the Portland District of the U.S. Army Corps of Engineers (USACE), the USGS evaluated \nsediment transport and gravel storage along the downstream alluvial reaches of the North and \nSouth Umpqua Rivers and the entire mainstem Umpqua River. This includes the lower 46.8 \nkilometers (29.1 miles) of the North Umpqua River and the lower 122.6 kilometers (76.2 miles) \nof the South Umpqua River. \n\t\t\nThe Umpqua River gravel transport study involved multiple analyses, including tracking patterns \nof historical channel change and estimation of a sediment budget. To support these analyses, \ndigital channel maps were produced to depict channel and floodplain conditions along the \nUmpqua River system from different time periods.\n\t\t\nGIS layers defining the active channel of the Umpqua River system were developed for three \ntime periods: 1939, 1967, and 2005. For the South Umpqua River and the 19 kilometers (12 miles) \nof the mainstem Umpqua River downstream from the confluence of the North and South Umpqua \nRivers, GIS layers were also developed for the time periods 1994, 2000, and 2009.\n\t\t\nFor this project, the active channel was defined as area typically inundated during annual high \nflows, and includes the low-flow channel as well as side channels, islands, and channel-flanking \ngravel bars. The active channel datasets were developed by digitizing from aerial photographs. \nAerial photographs from 1939 and 1967 were scanned, rectified, and mosaiced for this project. \nDigital orthophotographs from 1994, 2000, 2005, and 2009 are publicly available (See metadata \nfor each photograph set for more information on the rectification process and resolution of each \ndataset). Although our study area encompasses the Umpqua River and lower reaches of the \nNorth and South Umpqua Rivers, the extent of each dataset depended upon the underlying \naerial photographs; for example, the 1967 photographs extend only as far downstream as \nfloodplain kilometer 7, whereas the 1939 and 2005 datasets extend to the mouth of the \nUmpqua River at the Pacific Ocean.",
