The Blue Watershed (HUC 11140102) covers an area of 1,183 square miles in the state of Oregon, USA. It is primarily fed by snowpack, with the average snow water equivalent ranging from 20-30 inches. The watershed is home to several significant surface water bodies, including Blue River Reservoir and Cougar Reservoir. The reservoirs are used for both recreation and hydroelectric power generation. The watershed is also notable for its unique geology, with the presence of volcanic rocks and ancient sedimentary formations. Climate trends in the area include increasing temperatures and decreasing snowpack, which have significant impacts on the hydrology of the watershed. The area is also prone to intense precipitation events, which can lead to flooding and erosion. Management strategies for the Blue Watershed include efforts to protect and restore riparian habitats, reduce erosion, and improve water quality.
