About CCRCD Watersheds, News & Events

Welcome to the CCRCD’s Watershed Program Blog!

Welcome to the CCRCD’s Watershed Program Blog! Here, we will let you know about upcoming events, and we’ll post watershed-related news, resources, and project updates. We’ll share images and ideas that inspire us to work hard every day to preserve the natural resources of Contra Costa County. We think they’ll inspire you, too!

Watersheds

A watershed can be small, such as a modest inland lake or a single county. Conversely, some watersheds encompass thousands of square miles and may contain streams, rivers, lakes, reservoirs, and underlying groundwater that are hundreds of miles inland. The largest watershed in the United States is the Mississippi River Watershed, which drains 1.15 million square miles from all or parts of 31 U.S. states and two Canadian provinces stretching from the Rockies to the Appalachians!

Water from hundreds, and often thousands, of creeks and streams flow from higher ground to rivers that eventually wind up in a larger waterbody. As the water flows, it often picks up pollutants, which may have sinister effects on the ecology of the watershed and, ultimately, on the reservoir, bay, or ocean where it ends up. Not all water flows directly to the sea, however. When rain falls on dry ground, it can soak into, or infiltrate, the ground. This groundwater remains in the soil, where it will eventually seep into the nearest stream. Some water infiltrates much deeper, into underground reservoirs called aquifers.

Alhambra Creek Watershed

"The Alhambra Creek Watershed covers approximately 16.5 square miles in north central Contra Costa County in Northern California and encompasses a portion of the City of Martinez. Its upper portions are wooded/grassy ridges and slopes, which collect runoff for threemain stem streams. The combined branches flow through valleys containing open space, wildlife habitat, residential and commercial areas, through downtown Martinez and then discharge into the Carquinez Straits through a tidal wetland." (Alhambra Creek Watershed Management Plan, Alhambra Creek Watershed Planning Group, April 2001, p. 24).

The Alhambra Creek Watershed Planning Group has evolved into the Alhambra Watershed Council of today.
