San Luis Obispo County Watersheds
A Watershed Approach
A watershed is the area of land where all of the water that is under it, or drains off of it, goes into the same place. A watershed approach is the most effective framework to address today’s water resource challenges. Watersheds supply drinking water, provide recreation and respite, and sustain life. More than $450 billion in food and fiber, manufactured goods, and tourism depends on clean water and healthy watersheds.
