The USGS Wyoming-Montana Water Science Center (WY–MT WSC) recently completed a report (Sando and McCarthy, 2018) documenting methods for peak-flow frequency analysis following implementation of the Bulletin 17C guidelines. The methods are used to provide estimates of peak-flow quantiles for 50-, 42.9-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual exceedance probabilities (AEPs) for selected streamgages operated by the WY–MT WSC. In association with the report, this data release presents peak-flow frequency analyses for 14 selected streamgages in the Beaverhead River and Clark Fork Basins that were based on methods described by Sando and McCarthy (2018). The results are presented in three child items: a child...

The U.S. Geological Survey (USGS) New England Water Science Center worked with the Federal Emergency Management Agency to document the floods of January 4, 2018 and March 2-4, 2018, in coastal Massachusetts. USGS conducted a frequency analysis of stillwater elevations at three National Oceanic and Atmospheric Administration coastal gages following the coastal floods of 2018. The data for these analyses for gages in Boston, Massachusetts, Portland, Maine, and Seavey Island, Maine are included in the child item "Data to Support Stillwater Analyses." Stillwater elevations recorded in January 2018 in Boston (9.66 feet in the North American Vertical Datum of 1988, NAVD88) had an annual exceedance probability (AEP)...

Lake-bottom sediment and associated quality-control samples were collected in August 2020 from one coring location (U.S. Geological Survey station 413756070321301, ASHUMET POND, MASHPEE MI-ASHPD-0011) in Ashumet Pond downgradient from a former fire-training area on Cape Cod, Massachusetts. The core was collected to determine if per- and polyfluoroalkyl substances (PFAS) were present in the bottom sediments of a lake known to have elevated concentrations of PFAS in surface water and groundwater (Tokranov and others, 2021), and whether the sediments could act as a continuous source of PFAS to the lake. Processing the sediment core entailed collection of discrete samples at intervals ranging from 1-5 centimeters (cm)...

Managed aquifer recharge is a water-management strategy used to meet water demands during dry periods, or periods of high-water demand, when surface-water supplies are low. One method of managed aquifer recharge uses aquifer systems as subsurface reservoirs or ‘water banks’ to effectively and economically store surface water when surplus is available, and then recover the recharged groundwater to meet water demands during droughts. During these water shortages, increased groundwater pumpage can be used to offset shortfalls in surface-water supplies. Thus, surface-water reservoirs and water banks can be used conjunctively to effectively coordinate the use of groundwater and surface water. Data were compiled for ten...

Current estimates of the magnitude and frequency of floods at gaged and ungaged stream sites are critical for assessing flood risk, delineating flood zones, designing hydraulic structures, and managing flood plains. The Connecticut Department of Transportation collaborated with U.S. Geological Survey (USGS) in a study to improve the flood-frequency estimates in Connecticut and develop regional regression equations for estimating annual exceedance probability discharges at ungaged sites in Connecticut. The results of the study are found in Scientific Investigations Report (http://doi.org/10.3133/sir20205054). This companion data release consists of data compiled and used for the flood-frequency analysis of annual...

Locations of focused (or ‘preferential’) groundwater discharge to surface water are often hydrologically and ecologically important, yet our ability to predict the spatial distribution and water quality of preferential riverbank discharges is limited at the scale of river networks. To advance the understanding of the physical controls on riverbank groundwater discharge processes, discharge zones can be mapped efficiently using handheld and drone-based thermal infrared cameras. Groundwater discharge locations can be identified based on ‘anomalous’ thermal signatures, such as relatively cold riverbank zones in summer and warm riverbank zones in winter. Thermal infrared imaging can be combined with concurrent direct...

USGS met with 13 local groups and organizations around the Portland, Oregon region to collect information regarding the locations of beaver dams in the Tualatin Basin. The local sources had identified beaver dams between 2011 and 2019, and data were compiled by USGS into an ArcGIS shapefile. Often, the local groups did not know the GPS coordinates of beaver dams, but they had identified beaver-affected reaches during that same time period. Therefore, a second shapefile was created to include the locations of beaver activity (including beaver chews, lodges, and dams) in the Tualatin Basin. The Beaver Dam Locations ArcGIS shapefile shows the known locations of beaver dams in the Tualatin Basin. The Beaver Activity...
