Our Resident Bald Eagles

The land that we own in the Southern Alameda Creek Watershed has been protected for over a century.  By controlling the activities on our watershed lands, we ensure top water quality for our customers and preserve prime habitat for rare and endangered species. The 36,000 acres the SFPUC owns have become an oasis.

These lands are home to all sorts of plants, insects, and critters, including the Most Beautiful Jewel Flower, Callippe Silverspot Butterfly, California Tiger Salamander, California Red-Legged Frog, Alameda Whipsnake, Golden Eagles, and not one, but two nesting pairs of Bald Eagles.

Interestingly, both eagle pairs nest not far from our ongoing construction projects at Calaveras Dam and at the habitat restoration project at San Antonio Reservoir.

Our environmental teams monitor the eagles’ success annually and establish a wide “No Disturbance” boundary around the eagle nests, in coordination with the US Fish and Wildlife Service and California Department of Fish and Wildlife, to avoid aggravating nesting bald eagles. During nesting season, teams closely monitor the eagles’ activity around both reservoirs to ensure our construction work does not affect nesting birds. We go to great lengths to ensure that these special animals continue to thrive.
We are proud to announce that the eaglets (two at Calaveras and two at San Antonio) of both eagle pairs are very close to fledging!  The young eagles will continue to receive care from the parents for a while before exploring new territories on their own.  The parents – soon to be “empty nesters”  – will likely stay in the neighborhood to take advantage of the plentiful food source and relative isolation and protection the southern Alameda Creek watershed provides.
