The San Leandro Channel runs between Alameda and Oakland. Known locally as "the estuary", it is a tidal channel that links the freshwater streams of the east hills with the ocean.  Every 24 hours, the fresh water in the channel flows out into the San Francisco Bay and then, as the current reverses with the tides, it flows back as salty water. Such water is termed "brackish" and the wildlife and plants in the ecosystem all adapt for living with these cyclic changes.  I find it a metaphor for life, which has inspired my ongoing sculpture series.
