Sycamore Creek

Sycamore Creek

Sycamore Creek is a perennial stream in Contra Costa County, California, USA. [United States Geological Survey, "7.5 Minute Diablo, California Topographic Quadrangle Map", (1953, photo revised 1968 and 1973), U.S. Government Printing Office, Washington DC] There is an associated trail along a portion of the creek, which trail has been deveoped by the city of Danville, California and the East Bay Municipal Utility District.

In the late summer very low flows are realized; moreover, in the late summer, which is toward the end of the dry season, the waters appear murky green, and much of the creek consists of a chain of stagnant pools. No noticeable odors emanate from this stream. Concrete and rock reinforcements are present all along the creekbed in much of the stream. The creek receives surface runoff from open space and residential land use. A fairly rich but narrow corridor of riparian vegetation appears along the much of the middle reach creek bed, including cattails, numerous tree species, and a variety of herbaceous plants. ["Environmental Site Assessment for the Cameo Crest Subdivision, Danville, California", Earth Metrics Incorporated, July 18, 1989] The creek flows at considerable force during the rainy season (November to March), and once a week in the summer water is released from a private reservoir upstream located next to Old Blackhawk Road.

The headwaters of Sycamore Creek rise on Mount Diablo, a protected nature reserve. This scenic upper reach has some Miocene fossil-bearing formations. [ [ Geology of Mount Diablo] ] ] ; moreover, the upper headwaters reach is habitat for numerous rare species and endangered species including several serpentine endemics. Much of the middle reach five miles of Sycamore Creek reveal limited potential for hazardous materials contamination, as the developments abutting the stream bed consist of a country club, residential development and rural land use.
