Geochemical Data Release for Idaho Primitive Area, including the contiguous Clear Creek-Upper Big Deer Creek Area, the Salmon River Breaks Primitive Area, the Sawtooth Primitive Area, and adjacent areas, central Idaho (ver. 1.2, June 2022)

This U.S. Geological Survey (USGS) data release (ver. 1.2, April 2022) contains a set of previously unpublished geochemical data from project studies of primitive areas in central Idaho, including the Clear Creek-Upper Big Deer Creek Area, the Salmon River Breaks and Sawtooth Primitive Areas, and the Gospel-Hump Wilderness Area. The purpose of the USGS Idaho Primitive Area studies, conducted from 1966 to 1984, was to describe the geology, determine petrologic and geochemical characteristics, and evaluate the mineral resource potential of these primitive areas and adjacent study areas. In the case of the Idaho Primitive Area study (Cater and others, 1973), the primitive area covers 1,915 square miles; adjacent...

Effects of spring prescribed burning and wildfires on watershed nitrogen dynamics of central Idaho headwater areas

Conclusions: Prescribed burns did not supply the stream ecosystem with potentially important nutrient pulses that are often observed after wildfires. Prescribing higher severity burns to more closely mimic wildfires would enhance N cycling in productivity in N-limited headwater watersheds. Thresholds/Learnings: Synopsis: This study aimed to compare the short-term effects of spring prescribed burns and wildfires on Nitrogen cycling dynamics in headwater watersheds of central Idaho. Fire affected N dynamics in both terrestrial and aquatic components of the watershed ecosystem after wildfires but were limited to the terrestrial ecosystem after prescribed burns. Streamwater NO3 concentrations were affected significantly...

Bathymetric and Topographic Surveys at Black Canyon Reservoir, Gem County, Idaho, 2024

In August 2024, the U.S. Geological Survey Idaho Water Science Center (USGS IDWSC), in cooperation with the United States Bureau of Reclamation (USBR), completed bathymetric and topographic surveys at Black Canyon Reservoir near Emmett, Idaho using a multibeam sonar and boat-mounted Light Detection and Ranging (LiDAR). The bathymetric and topographic data generally include complete data coverage from Black Canyon Dam to Black Canyon Park with sparse data coverage upstream of Black Canyon Park and data represent conditions on August 19-20, 2024 when the water surface elevation was steady at about 2,497.8 feet (Reclamation Project Vertical Datum). Prior to the bathymetric and topographic surveys, USBR completed aerial...
