Description
- Abstract: Five of the six native Lahontan cutthroat trout (Oncorhynchus clarki henshawi) populations in Oregon exist in the Coyote Lakes basin of southeast Harney County (ODFW 2005). The major drainage's in the Coyote Lakes Basin are Willow and Whitehorse Creeks. Both drainage's originate on the north slope of Trout Creek Mountain, terminate in the dry Coyote lake bed and are currently isolated from each other or any other basin. Populations of Lahontan cutthroat in Willow and Whitehorse Creeks have been protected under the ESA as a threatened species since 1991 and are also listed as threatened under State of Oregon statute (Hanson et al.1993).
Along with changes in management and land use activities, the federal recovery plan for Lahontan cutthroat trout requires the assessment of habitat conditions and population abundance at five year intervals (Coffin and Cowan 1995). Population monitoring of cutthroat in Willow and Whitehorse creeks was initiated in 1985 and has occurred on a five year interval since then (Jones et al. 1998, ODFW Aquatic Inventory Project unpublished data). The goals of this project was to continue population monitoring by obtaining an estimate of Lahontan cutthroat trout in Willow Creek and Whitehorse Creek, and to test the application of the EMAP sampling design (Stevens and Olsen 2004) to obtain this estimate. Additionally, we determined distribution of cutthroat trout in tributaries where presence was suspected but not verified, and monitored distributions of the Antelope Creek populations.
