Groesbeck-Sandy

Watershed Hydrology

The Groesbeck Sandy Watershed covers approximately 219 square miles in central Idaho. The watershed is primarily made up of forests, with some agricultural areas, and is home to several species of fish, including Chinook salmon and steelhead trout. The hydrology of the watershed is heavily influenced by snowpack, with the majority of the water supply coming from snowmelt in the spring and early summer. The watershed has several small reservoirs used for irrigation, but they have been found to contain elevated levels of sediment and nutrients, which can impact water quality. In recent years, the Groesbeck Sandy Watershed has experienced warmer and drier conditions, which have affected snowpack levels and water availability. These trends are expected to continue in the future, leading to potential challenges for water management and ecosystem health in the watershed.
