MB Watershed

A watershed is an area of land that drains rainwater to a common waterway, such as a stream, lake, estuary, or even the ocean.

The Morro Bay estuary watershed includes the town of Los Osos, portions of Morro Bay, farms and ranches, parks, national forest, highways and more. The size and shape of the 48,000-acre Morro Bay Watershed is not determined by people or politics. The shape of the watershed is determined by the topography of the land...mountains, hills and valleys determine the direction rainwater flows.

As rainwater drains from our yards, hillsides and streets it carries pollution with it. Think twice before you dump cleaners, paint, oil and other chemicals on your yard, in the storm drain or in the street. How we use the land in the watershed impacts the quality of the water that flows into our creeks and estuary.

The MBNEP implements many projects in the watershed including stream restoration, land acquisition and conservation easements, revegetation projects and more.
