The C J Idaho watershed (HUC 17050101) covers a land area of approximately 1,158 square miles and is located in the southwestern part of Idaho. The watershed is characterized by the presence of diverse hydrological systems, including snowpack, surface water, and reservoirs. Snowpack in the watershed is typically concentrated in the high elevation areas and melts during the spring and summer months, contributing to surface water flow. The surface waters in the watershed consist of a variety of channels and streams, which support diverse aquatic life. The reservoirs in the area store water for various uses such as irrigation, power generation, and recreation. Interesting climatic facts and trends in the area include high temperatures during the summer months and low precipitation levels during the winter months. Additionally, the area has seen an increase in temperature and a decrease in snowpack in recent years, which could have significant impacts on the hydrological systems of the watershed.
