Watershed Restoration

INTRODUCTION

The Watershed Restoration Program initially began in 1991 and is a cooperative partnership between the Upper San Gabriel Valley Municipal Water District and the U. S. Forest Service to protect and maintain the local watershed.

Why is this Program Important?

Fires, mudslides and the encroachment of non-native vegetation have caused accelerated erosion which, in turn, causes siltation of the canyon reservoirs and stream beds. Siltation reduces the water conservation and storage capacity of the reservoirs as well as the percolation capacity of stream beds and spreading grounds. Heavy recreational use has also had a negative impact on the local habitat by causing a reduction in the riparian vegetation which in turn has caused the destabilization of the river bank resulting in increased soil runoff directly into the river with subsequent siltation problems downstream.

By replanting local areas with native vegetation, soils will not erode so quickly which will allow rain and other precipitation to percolate into the ground and make its way into our local aquifer. The vegetation will also help alleviate siltation that causes increased blockage of waterways and filtration systems.
