The U.S. government has designated Zayante Creek as impaired with respect to sediment.[2] Lompico Creek, a tributary of Zayante Creek, is listed for impairment by pathogens.[3] In the period 1998 to 2000 a restoration project was conducted for this stream to improve anadromous fish passage, rearing and spawning.[4] There has been a permanent U.S. Geological Survey gauging station on Zayante Creek which has operated since the year 1959; the mean altitude of the Zayante Basin, carved within the western slopes of the Santa Cruz Mountains, is 1,000 feet (300 m).[5] Significant tributaries to Zayante Creek are Lompico Creek and Bean Creek.

Soils formations along the mainstem of Zayante Creek by ascending altitude are: Monterey Formation, Zayante Formation, Vaqueros Sandstone and Lompico Sandstone;[6] about midway through its course, Zayante Creek is bisected by the Zayante Fault. Several notable ecological features are present in the Zayante Creek watershed, including the occurrence of a rare forest type: maritime coast range ponderosa pine forest, which contains two endangered arthropods. Regarding specific avafauna species there are sightings of Townsend's warbler.[7]
