Topic	Habitat Typing: Kass Creek Embeddedness

 

Caption:  Gravel embeddedness is a measure of gravel quality at potential salmonid spawning sites taken ocularly during habitat typing surveys. Embeddedness is the degree to which substrate in pool tail crests are buried. Optimal spawning habitat according to CDFG (1998) is less than 25% embedded (see InfoLinks). Kass Creek showed substantially impaired spawning habitat suitability with 69% of pool tail crests showing greater than 75% embeddedness. This measure is far less useful for determining gravel suitability and trends than quantitative methods such as McNeil samples. The length of the survey was 9,815 feet or 1.9 miles. Data collected by Georgia Pacific and supplied for use in KRIS by the California Department of Fish and Game, Sacramento, CA.
