The Upper Mokelumne River Watershed Authority (UMRWA, or Authority) is a Joint Powers Authority comprised of six water agencies and the counties of Amador, Calaveras and Alpine. The six water agencies are Amador Water Agency, Calaveras County Water District, Calaveras Public Utility District, East Bay Municipal Utility District, Jackson Valley Irrigation District and Alpine County Water Agency.

The Authority is governed by an eight member Board of Directors which meets quarterly. Open to the public, the governing Board meetings are typically held at Pardee Center about 4 miles north of Valley Springs. Click here to read about the history of the Authority.

Much of the land within the Upper Mokelumne River Watershed is managed by federal agencies and by owners of large private land holdings, with city and county governments overseeing local land use decisions and special districts generally providing water and other utility services. UMRWA's role is to perform water resource planning for the region and seek and secure grant and other funding for local agency implementation activities.

UMRWA's goals to enhance water supply and protect water quality and the environment are fulfilled in a variety of ways. Serving as the regional water management group for the Mokelumne-Amador-Calaveras Region, UMRWA has developed the MAC Plan, a state approved integrated regional water management plan. UMRWA also supports the Youth Watershed Stewardship Program, a public education program lead by Stewardship through Education, an organization of teachers. Looking inter-regionally, UMRWA is working with the Eastern San Joaquin Region on a Mokelumne watershed resource plan called MokeWISE to address resource issues in both the Upper and Lower watersheds.

The Authority will continue to seek out opportunities for water resource planning and implementation initiatives that serve the interests of its Member Agencies and those they serve. Click on the links in the left hand panel to find out more about UMRWA's watershed projects and programs.

The Authority was formed in the year 2000 to address regional concerns related to PG&E's anticipated divestiture of its Mokelumne River Hydropower Project as then called for under California's energy deregulation legislation. Acquisition of PG&E's Mokelumne River Project was UMRWA's primary objective during these initial years. When the US Federal Court approved PG&E's bankruptcy reorganization plan, Authority member concerns regarding the divestiture of the Mokelumne River project were generally abated and UMRWA acquisition efforts halted.

Following the elimination of the PG&E project acquisition as its objective, UMRWA in 2005 shifted its focus. New priorities relative to water quality issues and potential watershed projects were identified. Cooperative water supply planning efforts were also developed for the Authority's member agencies through the inter-regional water resource collaborative known as the Mokelumne Water Forum.

Shortly after the Integrated Regional Water Management Act was passed in 2008, the Authority expanded its purpose by assuming responsibility for water resource planning in the Mokelumne-Amador-Calaveras (MAC) Region. UMRWA was approved in 2009 by the California Department of Water Resources (DWR) as the regional water management group for the MAC Region. The MAC Region was also approved and formally recognized by DWR as an Integrated Regional Water Management region.

From its founding in 2000, the Authority has served as a venue for addressing water resource issues of concern to those who enjoy and rely on them. Working in collaboration with agencies, organizations, and individuals within the MAC and neighboring regions, UMRWA has secured millions of dollars in grant funding to develop and implement broadly supported water resource solutions.

The Upper Mokelumne River watershed is located along the west slope of the Sierra Nevada mountain range in Central California. The topography of the watershed is hilly to mountainous, with watershed elevations ranging from 600 feet to 10,400 feet at the Sierra Nevada crest. The entire 550 square mile watershed is located within Alpine, Amador and Calaveras Counties. Like many Sierra Nevada west slope watersheds which lie in proximity to urbanizing central valley communities, growth within the Upper Mokelumne River watershed is not a question of if, but when. The areas of highest concentrations of development lie in the western most portions of the watershed. Many of these communities originated during the gold rush era, and the aging infrastructure developed over the past many decades continues to be stressed by the demands of an increasing population and more stringent regulatory requirements.

The Youth Watershed Stewardship Program is a partnership between UMRWA, the Central Sierra Resource Conservation and Development (CSR&D) and its educational partner, Stewardship Through Education, LLC (STE). Funded and supported by UMRWA member agencies, the program reaches about 1,000 students each year in Amador and Calaveras counties. Children from traditional public schools, court schools and those in home schools have all participated in our programs. The CSRC&D and STE have forged partnerships with local water agencies, county governments, environmental educators and community groups resulting in new outdoor education opportunities for children. Program accomplishments since its inception in 2005 include the following:

(a) Published Circles and Cycles, the Upper Mokelumne River Watershed Guide for Educators in Calaveras and Amador Counties, a K-12 curriculum with in-class and field trip lesson plans

(b) Developed Watershed Science Service Learning Module, stream-based high school science methods and lessons

(c) Conducted annual in-service teacher training for Circles and Cycles

(d) Mentored teachers in environmental education and associated field and lab activities, including web-based technical support, to achieve and maintain teacher self-sufficiency

(e) Maintained lending library of monitoring equipment, water testing kits, and science modules

(f) Provided grants to pay transportation costs to visit local streams, lakes, and water and wastewater treatment facilities

The guide, Circles and Cycles, the Upper Mokelumne River Watershed Guide for Educators in Calaveras and Amador Counties, has six themes relating to stewardship of the watershed: Interdependency, Sense of Place, Journey of Waters, Riparian Habitat, Earth's Many Forces and California-the Changing State. These themes include lessons that help students map their own water supply, act out the water cycle, understand water and wastewater treatment, learn native plants and their uses by Native Americans, and study life cycles of aquatic invertebrates and salmon. In all three counties, water and wastewater agencies have agreed to have students visit their treatment facilities.

In the Watershed Science Service Learning Module, in-class and field lessons introduce young science students to water quality testing and the importance of these parameters to stream health. Students also measure numerous instream and bank features to evaluate whether physical features support aquatic life. Students evaluate land use impacts in the classroom and the likely impacts on streams. In keeping with the recent development of bio-criteria to identify cumulative adverse impacts to streams, students collect and categorize benthic macro-invertebrates, then evaluate stream health based on abundance, species tolerance, and biodiversity.
