The approximately 2,700 square miles of the Tuolumne-Stanislaus Integrated Regional Water Management (T-Stan IRWM) Region span the entire western slope of the Sierra Nevada, encompassing the Upper Tuolumne River, Upper Stanislaus River, and Upper Rock Creek-French Camp Slough Watersheds. The Region includes all of Tuolumne County, the southern portion of Calaveras County, and southwestern Alpine County.
Funded by the T-Stan IRWM Authority, the following link provides access to the newly developing Stormwater Project Identification Tool (SPIT). https://arcg.is/nnPC0
Supported in large part by the California Department of Water Resources, the region launched its first integrated data management program. The following interactive map depicts information about projects undertaken through the T-Stan IRWM and the region it serves. More project information will be provided as it becomes available. A larger version of this map is available at: T-Stan IRWM Projects Map.
