Tule Ponds at Tyson Lagoon is a "Wetland
in the City." This innovative area is used for flood
control but also as a wildlife sanctuary for the many species
that live in an urban environment. Since the land is 17
acres is is being restored to the flora of a San Francisco Bay
area of at least 1 million years old. Native trees, shrubs, and
flowers are being introduced which then bring some of the native
fauna.
The natural lake is caused by the breach in
the underground water source (aquifers) by the Hayward fault
that dissects the region. This causes what is called a "sag
pond." The 3 ponds are constructed and with time they will
become a natural wetland.
We are not open to the public, but if you are
interested in seeing the facility please sign up for one of our
tours or volunteer opportunities.
