         Meet MRWG


Hello! Welcome to the home of the Mojave River Watershed Group (MRWG) – an organization that is committed to the protection of the Mojave River, its Watershed, plants and wildlife, and the quality of our regularly used High Desert water against the adverse effects of stormwater pollution.

Our team is comprised of representatives from the cities of Hesperia and Victorville, the Town of Apple Valley, and the County of San Bernardino. We are all dedicated to leading a stormwater pollution revolution by influencing behavior change in community leaders, residents, business owners and schoolchildren to reduce stormwater pollution.

Protecting the High Desert community is easy! We encourage you to browse our site to learn about Best Management Practices (BMPs) and pollution prevention tips. We’re confident you’ll find that simple changes in everyday behavior go a long way to protect our Mojave River and its Watershed.

Need a Definition for Stormwater Pollution?

No problem. Let us explain.

Stormwater Pollution in the High Desert: water that becomes polluted by litter, pesticides, fertilizer, motor oil, pet waste and more, and flows directly over land and roads to the Mojave River or into an untreated stormdrain system. This water is contaminated and harmful to the health of our families and local wildlife.
