About ARWIN
Study Area
The Upper American River Basin in the Northern Sierra Nevada, California, covering the North, Middle, and South Forks of the American River. The watershed spans from the peaks west of Lake Tahoe to Folsom Lake, encompassing approximately 2,100 square miles.
Project Goals
ARWIN aims to improve hydrologic monitoring and forecasting by understanding how changes in runoff patterns from droughts and wildfires affect water resources, analyzing precipitation processes, and evaluating snowpack evolution to support water and power management decisions.
Data Applications
The hydroclimatic information system supports critical applications including water supply forecasting, flood planning, drought management, and hydropower operations throughout the American River Basin region.
