Reliable peak-streamflow information is critical for proper design of stream-related infrastructure, such as bridges, and StreamStats provides a user-friendly interface to estimate peak flows (https://streamstats.usgs.gov/ss/). StreamStats develops these peak-flow estimates using basin characteristics for the entire contributing area to a user-selected point; however, infrastructure planners often need to estimate flows for an area downstream from a known control such as a reservoir release or a weir. This dataset was compiled in cooperation with the South Carolina Department of Transportation (SCDOT) to provide a Geographic Information Systems layer of filtered regulation points from the National Inventory of Dams...

This spreadsheet compiles all longitudinal survey data collected along Redwood Creek during the thirty year period, 1977-2007. Long-term surveys were conducted along three reaches of Redwood Creek: Elam to Hayes creek reach, Dolason to Wier (Emerald) creek reach, and Bond to 44 creek reach. Longitudinal streambed surveys follow the channel thalweg (deepest point) and are useful in documenting aquatic habitat conditions (for example, pool depth distribution, percent length in riffles vs pools). Each of these surveys was conducted in the summer months of each recorded year and took about two weeks to complete.
Degradation of water quality is the major health concern for lakes and reservoirs in the central regions of the United States as a result of heavily devoted agricultural production. A vital key to the development of a reservoir management strategy is to identify nutrient loading that describes associated water quality conditions in reservoirs. This study integrated AnnAGNPS watershed and BATHTUB lake models to simulate actual lake water quality conditions of Cheney Reservoir, KS, and demonstrated the use of the coupled model for simulating lake response to changes in different watershed land use and management scenarios. The calibrated current-conditions model simulated in-lake reductions as much as 52% for TN,...

This data release documents the datasets and procedures used to update the Los Angeles Basin Watershed Model (LABWM) (Hevesi and Johnson, 2016) from INFIL3.0 (USGS, 2008a, 2008b) to INFIL4.0. The LABWM provides gridded monthly infiltration, evaporation, recharge, and runoff estimates for the Los Angeles region using the water balance recharge model, INFIL. INFIL is a grid-based, distributed-parameter, deterministic model that uses a daily time step to simulate the temporal and spatial distribution of the root-zone water balance, including net infiltration and potential recharge across the lower boundary of the root zone. INFIL3.0 was originally released and documented in 2008 (USGS, 2008a) and has been used and...

Reactive nitrogen is transported from the atmosphere to the landscape as wet and dry deposition that contributes to annual nitrogen loads to the Chesapeake Bay. Estimates of atmospheric inorganic nitrogen deposition to the Chesapeake Bay watershed during 1950 to 2050 are presented, and are based on field measurements, model simulations, statistical relations, and surrogate constituents used for estimates. Wet atmospheric nitrogen deposition has generally been quantified from weekly precipitation sample collections, whereas dry atmospheric nitrogen deposition has been simulated by a model at an hourly time step.

This data release contains one point shapefile describing cattle access to streams for three USGS showcase watersheds: Smith Creek, Conewago Creek, and Upper Chester River. This data release identifies areas where cattle were able to access the stream, as well as possible cattle access areas. Streams were defined using a combination of geospatial data and aerial imagery and cattle access points were determined by locating cattle paths adjacent to stream morphology.

This ArcGIS shapefile shows the known locations of beaver activity (including beaver chews, lodges, and dams) in the Tualatin Basin. USGS was intending to collect information about the locations of beaver dams. Often, the GPS coordinates of dams were not known, but the beaver-affected areas were known. The information about locations with beaver activity was generated by multiple local agencies, groups, and organizations. The local sources had identified the beaver activity locations between 2013 and 2016. USGS worked with these local sources to combine all data into one inventory.
