In 2016, the Department of Water Resources updated the standards for Integrated Regional Water Management Plans (IRWMPs). To meet these new requirements and maintain funding eligibility, the Mokelumne-Amador-Calaveras (MAC) Region led by the Regional Participants Committee (RPC) prepared the 2018 MAC Plan Update. In preparation for Proposition 1 Round 2 IRWM funding, the Region updated its project list in late 2021 and captured these updates in a 2022 Addendum. Both the Final 2018 Plan and the 2022 Addendum are available on the Documents page. UMRWA adopted the 2018 MAC IRWM Plan at their January 25, 2019 Board meeting and the 2020 Addendum at their January 28, 2022 meeting.

Integrated Regional Water Management (IRWM) Planning

California's Integrated Regional Water Management Act of 2002 set forth a new way of thinking about water resource planning by promoting Integrated Regional Water Management plans (IRWMPs) to increase collaboration between local agencies. The goal is to ensure sustainable water uses, reliable water supplies, better water quality, environmental stewardship, efficient urban development, protection of agriculture, and a stronger regional economy. Administered by the California Department of Water Resources (DWR), the State IRWM program encourages creation of Regional Water Management Groups (RWMGs) and the use of collaborative processes to develop IRWMPs which target regional water resource issues. DWR supports and promotes the integrated regional planning work of RWMGs by providing funding through competitive grants.

MAC IRWM Region Background

The Mokelumne-Amador-Calaveras (MAC) IRWM planning effort was initiated in 2006 as a cooperative effort by Amador Water Agency (AWA), Calaveras County Water District (CCWD), Amador County, City of Jackson, City of Sutter Creek, City of Plymouth, Amador Regional Sanitation Authority (ARSA) and East Bay Municipal Utility District (EBMUD). These entities entered into a Memorandum of Understanding (MOU) for the purposes of coordinating water resources planning and implementation activities and formed the official MAC region RWMG, with AWA assuming the role of region administrator for the RWMG.

In 2009, the Upper Mokelumne River Watershed Authority assumed lead agency responsibilities with respect to the MAC Region IRWM program. In fulfilling this RWMG role, UMRWA established the Regional Participants Committee (RPC). The RPC is a committee of city, county, special district, non-governmental organizations, and federal agency stakeholders which provided essential input and guidance to the development of the 2013 MAC Plan Update. The RPC has a continuing role in both maintaining the Plan's list of implementation projects and programs, and in future Plan updates whenever such updates are determined necessary and appropriate.

MAC Plan and RPC documents are accessible on the Documents page.

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.
