UMRWA's stewardship initiatives in the Upper Mokelumne River watershed are administered through two programs, the Forest Program and the Integrated Regional Water Management (IRWM) Program.

Forest Program: Under a 2016 Master Stewardship Agreement with the US Forest Service UMRWA serves as lead partner for forest project planning and contracting fuel reduction and restoration projects within the watershed. 

IRWM Program: Serving as the IRWM 'regional water management group' for the Mokelumne-Amador-Calaveras (MAC) Region, UMRWA has developed the MAC Plan, a state approved integrated regional water management plan, and secured more than $11 million for infrastructure projects that benefit local communities.
