Two of the three ponds hold treated wastewater; the third is a freshwater pond with three islands that attract nesting birds. As you circle around the ponds on the trail network, you can see Mount Diablo to the east, Mount Tamalpais to the west, and all sorts of wildlife, including a fantastic array of waterfowl. On winter weekends, don’t be surprised if you see flocks of birdwatchers toting cameras and binoculars.

Description
Next to the classroom building by the parking lot, a steep concrete path leads across a bridge to the main trail. Just past the bridge is an accessible picnic area, although the table has no roll-under space. Two loop trails soon branch off and circle the storage ponds. On one loop I saw mergansers and a cinnamon teal paddling around an island in one of the ponds, and egrets searching the nearshore waters for a meal. The trail can be rocky and rough in places, with a few steep dips and rises, and portions of it are overgrown by weeds. The main trail continues along the north edge of a broad marsh. Eventually it becomes hard-packed dirt with irrigated fields on the left; then it turns to a rough footpath, where I turned back.
