Arroyo Hondo is a northwestward-flowing 13.0-mile-long (20.9 km)

Smith Creek and Isabel Creek which drain the west and east slopes of Mount Hamilton
, respectively.

History

Arroyo Hondo means "deep creek" in Spanish. Its Isabel Creek tributary is significant in that the Spanish name for Mt. Hamilton was the Sierra de Santa Isabel, and the highest point was then referred to as Mount Isabel instead of Mount Hamilton. When William Henry Brewer and Charles Hoffman of the Whitney Survey climbed the peak on August 26, 1861, they did not know it had a name, and christened it Mt. Hamilton, although they did correctly place Isabel Valley on their map to the east. When in 1895, the USGS realized that the peak two miles southeast of Mt. Hamilton was as tall (4,193-foot (1,278 m),[3] they correctly named it Mt. Isabel.[4]

Watershed

The Arroyo Hondo mainstem is formed by the confluence of

Smith Creek at the northern tip of Joseph D. Grant County Park at an elevation of 1,585 feet (483 m) above sea level.[5] It flows northerly to its confluence with Calaveras Reservoir at an elevation of 765 feet.[1] Isabel Creek begins at about 2,600 feet (790 m) about one mile south of Mt. Helen, then flows north through the Isabel Valley, then east and north of Mt. Isabel and Mt. Hamilton until it is joined by Smith Creek.[5] Arroyo Hondo joins Calaveras Creek in Calaveras Reservoir. Calaveras Creek is, in turn, tributary to Alameda Creek in Alameda County, California and ultimately flows into San Francisco Bay
.

Ecology

Arroyo Hondo still has remnants of native

steelhead trout (Oncorhynchus mykiss irideus) streams.[9][10] Speckled dace (Rhinichthys osculus) were collected by John Otterbein Snyder in 1898 in Arroyo Hondo and Isabel creeks, but not by Scoppettone and Smith in 1978, nor by Leidy and Bronwen in 2013, and their status in the creek remains uncertain as is true of most of their former sites in the central coast.[11][12]

Foothill yellow-legged frogs (Rana boylei) and California red-legged frogs (Rana draytoni) are present in Upper Alameda, Arroyo Hondo, Smith, and Isabel creeks.[6]
