Wallowa

Watershed Hydrology

The Wallowa Watershed is located in northeastern Oregon and is part of the larger Columbia River Basin. It covers a land area of approximately 1,214 square miles and is characterized by a diverse landscape that includes mountain ranges, valleys, and forests. The hydrology of the watershed is primarily influenced by snowpack and precipitation, with melting snow during spring and summer contributing to surface water and streamflow. The area also contains several reservoirs that provide irrigation and hydropower generation. Interesting climatic facts and trends for the Wallowa Watershed include the frequent occurrence of drought conditions, particularly during the summer months, and the potential for extreme weather events such as floods and landslides. Additionally, there has been an overall trend of decreasing snowpack levels in recent years, which could have significant impacts on the region's water resources.
