Sandhill-Wilson

Watershed Hydrology

The Sandhill Wilson Watershed (HUC 09020301) is located in southern Idaho and covers approximately 80 square miles of land area. The watershed is primarily composed of grasslands and sagebrush steppe, with intermittent streams and wetlands. The hydrology of the watershed is dominated by snowmelt, with peak flows occurring in late spring and early summer. The snowpack in the watershed is highly variable, with some years experiencing above-average snowfall and others experiencing drought conditions. Surface water in the watershed is primarily used for irrigation, and water quality is generally good. The reservoirs in the watershed are primarily used for irrigation storage, and are not used for recreational activities. Interesting climatic facts include the high variability of snowpack and precipitation, and the potential for drought conditions. Trends in the watershed include increasing temperatures and changes in precipitation patterns, which could have implications for water resources in the future.
