The data release for the geologic terranes of the Hailey 1 x 2 degrees quadrangle and the western part of the Idaho Falls 1 x 2 degrees quadrangle, south-central Idaho is a Geologic Map Schema (GeMS)-compliant version that updates the GIS files for the geologic map published in U.S. Geological Survey (USGS) Bulletin 2064-A (Worl and Johnson, 1995). The updated digital data present the attribute tables and geospatial features (lines and polygons) in the format that meets GeMS requirements. This data release presents the geologic map as shown on the plate and captured in geospatial data for the published map. Minor errors, such as mistakes in line decoration or differences between the digital data and the map image, are corrected in this version. The database represents the geology for the 6.1 million-acre, geologically complex Hailey quadrangle and the western part of the Idaho Falls quadrangle, at a publication scale of 1:250,000. The map covers primarily Blaine, Camas, Custer an ...

The downloadable ZIP file contains an Esri shapefile. This is a bathymetric data set of Coeur d'Alene Lake, Coeur d'Alene River, St. Joe River, and Spokane River. This data was derived from bathymetric contour lines created by Parametrix, Golder and USGS. The contour lines were interpreted by the ArcGIS using the "Topo to Raster" tool to produce raster surfaces (i.e. Digital Elevation Model (DEM)). For most of the project area the contour lines had a one-foot increment. The only exception to this was when USGS data was used for areas around the Lateral Lakes along the Coeur d'Alene River. Five-foot contour lines were then generated from the DEM. Contour attribute is displayed in feet above sea level.The original data sets used for the basis of this project were created for various studies of Coeur d'Alene Lake. Primarily, in relation to the re licensing of the Post Falls dam. This dataset was created to try to avoid many of the edge matching issues that arose around the original Parametrix data set. This data set will also be used to generate future contour lines of the lake and rivers.These data were contributed to INSIDE Idaho at the University of Idaho Library in 2004.

The Idaho Department of Fish and Game is divided into seven administrative regions with offices in Coeur d'Alene, Lewiston, Nampa, Jerome, Pocatello, Idaho Falls and Salmon. In addition, a subregional office in McCall operates in conjunction with the Southwest Region office. The headquarters office is located in Boise. All offices are open Monday through Friday, except state holidays, 8 a.m. to 5 p.m. Offices in the Panhandle and Clearwater regions are in the Pacific Time zone; all others are in the Mountain Time zone.For regional and headquarter office contact information: https://idfg.idaho.gov/offices

The State of Idaho, the United States of America, and other interested parties have signed stipulations for settlement of objections to instream federal reserved water rights claimed pursuant to the federal Wild and Scenic Rivers Act. These stipulated agreements are referred to as the Wild & Scenic Agreement. Under the Wild & Scenic Agreement, the parties quantified the federal reserved instream water rights on specific Wild & Scenic Rivers in Idaho. Not all Wild & Scenic rivers in Idaho fall under the provisions of the Wild & Scenic Agreement. Water rights subject to the agreement are sometimes called the "Wild & Scenic Water Rights." In addition to quantifying the Wild & Scenic Water Rights, the Wild and Scenic Agreement subordinated the Wild and Scenic Water Rights to certain existing and future water uses and required detailed administration of existing and new water rights to ensure water use conforms to all elements of the water rights. The provisions of the Wild and Scenic Agreement apply to hydraulically connected water sources above (upstream from) the ending points of the respective Wild & Scenic Water Rights. IDWR interprets the term "hydraulically connected sources" to mean all sources of water, including ground water, within the surface water drainages of the Wild & Scenic Rivers, upstream from the ending points of the Wild & Scenic Water Rights. All surface water rights and ground water rights diverted from sources hydraulically connected to the Wild and Scenic River reaches upstream from the ending points are recorded, tracked, and administered as anticipated under the provisions of the Wild & Scenic Agreement. This watershed dataset was created for use in water right administration and is associated with recording and tracking requirements of the Wild and Scenic Agreement. These watersheds do not have overlapping features but are clipped to the smallest watershed being administered.

The geology of the Thompson Falls 1:100,000 quadrangle, Idaho was compiled by Reed S. Lewis in 1997 onto a 1:100,000-scale topographic base map for input into an Arc/Info geographic information system (GIS). The digital geologic map database can be queried in many ways to produce a variety of derivative geologic maps.

Hydrilla is considered to be the most problematic aquatic plant in the United States. Most 2023 ISDA Hydrilla survey and treatment locations occur along the Snake River north of Twin Falls and northwest of Buhl as well as locations along the Bruneau River. Data fields include date, water temp, Hydrilla presence or absence, type of growth, type of mechanical treatment, number of plants, and number of tubers.For more information please visit our website.
