The Blue China Watershed (HUC 11130102) is located in the Pacific Northwest region of the United States and covers approximately 199 square miles. The area is characterized by high elevations, steep slopes, and dense forests, which make up the majority of the land cover. The watershed is drained by the Blue China Creek, which flows into the Yakima River. The hydrology of the Blue China Watershed is heavily influenced by snowpack, with snowmelt contributing to the majority of the surface water flow during the spring and early summer months. The reservoirs in the watershed are used primarily for irrigation purposes and are composed of sedimentary materials such as sand, gravel, and silt. Climatically, the Blue China Watershed experiences a semi-arid climate, with hot summers and cold winters. The area is prone to drought conditions, which can lead to decreased water availability and increased wildfire risk. Climate models suggest that the region may experience more frequent and severe droughts in the future as a result of climate change.
