The Lower Deschutes Watershed (HUC 17070306) covers approximately 3,169 square miles in central Oregon. The watershed is characterized by a semi-arid climate with hot summers and cold winters. The hydrology of the watershed is heavily influenced by the Deschutes River, which serves as the main source of surface water for the area. The snowpack in the area is typically light and melts relatively quickly in the spring, contributing to the river's flow. The watershed is home to several large reservoirs, including Lake Billy Chinook, which are used for irrigation, hydroelectric power generation, and recreation. Interesting climatic facts include the high temperature variability in the area, with the hottest temperature on record being 119°F and the coldest being -36°F. Trends in the area show an increasing demand for water resources, leading to conflicts between different users and the need for sustainable management practices.
