Watershed Hydrology

The Apple Watershed (HUC 10130103) is located in north-central Washington State and covers an area of approximately 1,001 square miles. The watershed is primarily composed of forested land, with small areas of agricultural and urban development. The hydrology of the watershed is dominated by the Wenatchee and Entiat Rivers, which have their headwaters in the Cascade Mountains. The watershed receives an average of 24 inches of precipitation per year, with the majority falling as snow. The snowpack in the watershed is an important source of water for irrigation and hydroelectric power production in the region. The surface water in the watershed is monitored for various constituents, including temperature, pH, dissolved oxygen, and nutrients. One interesting climatic trend in the watershed is the increase in temperature and decrease in snowpack over the past several decades, which has significant implications for water availability and management in the region.
