Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Contour Dataset of the Potentiometric Surfaces of Shallow and Deep Groundwater-Level Altitudes in Harney Basin, Oregon, February-March 2018 Contour Dataset of the Potentiometric Surfaces of Shallow and Deep Groundwater-Level Altitudes in Harney Basin, Oregon, February-March 2018
This dataset contains manually developed 5-, 10-, and 500-ft contours for the Harney Basin, Oregon aquifer system shallow and deep potentiometric-surface maps. The potentiometric-surfaces show altitude at the water-table surface (shallow) and at which the water level would have risen in tightly-cased wells deeper than 100 ft (deep) and generally represents synoptic conditions during...
Bighorn Sheep Risk of Contact Tool Bighorn Sheep Risk of Contact Tool
The Risk of Contact Tool (RoCT) is an R-based implementation of the Risk of Contact model described in O'Brien et al. (2014). It uses a variety of spatial inputs (including telemetry point data, a core herd home range (CHHR) polygon, a habitat raster model, and a set of active domestic sheep allotments) together with estimates of bighorn sheep foray behavior to estimate the probability...
