RWA has had a number of successes in a relatively short time, including:
- Facilitating implementation of a regional conjunctive use program that supports reduced diversions from the American River in dry years.
- Undertaking the preparation of the American River Basin Integrated Regional Water Management Plan, and overseeing its implementation.
- Developing the Regional Water Efficiency Program, which assists members in implementing water conservation best management practices in a cost effective manner and in communicating water efficiency information to the public.
- Tracking and responding to state and federal legislation and policy and its potential impact on members.
- Providing assistance for local water suppliers in implementing the historic Water Forum Agreement.
- Obtaining and managing more than $68 million of state and federal grant funds to conduct planning and implement water supply, water quality, and environmental restoration projects.
