 List
of San Fancisco Bay Region CCAs 
 The
San Francisco Bay region's watersheds include
freshwater and estuarine streams and rivers that serve a
vital habitat and as spawning areas for anadromous fish,
as well as supporting municipal and domestic drinking water
supply, agricultural and industrial process supply, water
recreation, and navigation uses. In addition to San Francisco
Bay itself, there are a number of water bodies of special
significance within the basin.
Watersheds within Marin County
(Lagunitas Creek, Olema Creek, and Redwood Creek) and San
Mateo Counties (Pescadero Creek and San Gregorio Creek)
provide some of the best habitats for threatened or endangered
coho salmon and steelhead populations in Central California. This
critical beneficial use is impaired in each of these watersheds
due to impacts from sedimentation and habitat degradation
(e.g., excess fine sediments, lack of large woody debris,
and lack of covered spawning gravels). There are also many
bayside watersheds that have important beneficial uses
for fishes and other aquatic species; in most cases these streams
have also suffered severe habitat degradation
due to urbanization and flood control projects.
 The
San Francisco Bay Region has a variety of water quality issues
to address. The Bay areas is highly urbanized and is affected
by all of the impacts associated with commercial, industrial,
and residential development, including wastewater and industrial
discharges, significant historical loss of wetlands through
diking and filling, widespread stream modification projects
for flood control and urban development, and contamination from
pollutants such as industrial chemicals, hydrocarbons, pesticides,
and legacy pollutants.
The
Region has seen a rapid expansion of residential development
within the past twenty years, which has lead to impacts from
increased impervious surface, storm water pollution, and changes
to stream channels, hydrographs and riparian zones. There are
also water quality impacts in the more rural areas of the Region
from grazing and agriculture, confined animal facilities, onsite
sewage systems, and land conversions. |
