As in previous years, sediments of the South Bay and southern sloughs generally had the highest contaminant concentrations. Mercury (Hg) concentrations in sediments in parts per million, dry weight (ppm) were sampled from February and August of 1997. More

Previous studies have correlated dredged sediment placed at high elevations (approximately 0.5 ft below MHHW) with poor tidal channel formation (LTMS 1994); if the high marsh goal does not depend on extensive channel formation, then such a concern would not apply. More

This study examined wildlife use and habitat in five salt ponds near Mowry Slough and Coyote Creek in Alameda County from September 1967 to September 1969. Salinity in the series of ponds ranged from 9 Sal. (percent of saturation) in low salinity ponds to 93 Sal. in high salinity ponds, and pond areas ranged between 430 - 590 acres.Numerous birds (55 species) utilized the salt ponds; the species making heavy use of the salt ponds included shorebirds, ducks, grebes and Bonaparte's gulls.
