Stehekin River Cutthroat Trout Spawning, Abundance and Genetic Surveys, NPS. North Cascades National Park personnel will conduct five to six trout spawning surveys in the spring and early summer of 2016, and will conduct two additional snorkel surveys of index sites in late summer/early fall to monitor trout abundance. Fry DNA will be collected from four index reaches to examine parental lineage and hybrid status. Table 3-10: Estimated 2017 NPS budget and schedule for westslope cutthroat trout surveys.

Stehekin River Cutthroat Trout Spawning, Abundance and Genetic Surveys, NPS. Due to the absence of WCT spawners in any of the 2009-2011 surveys it is recommended that spawning surveys be discontinued from 2012 to 2014 (see Section 2.2.3). Surveys should be reinstated in 2015 for a period of at least three years. Monitor trends in abundance of cutthroat and rainbow trout spawners at 10 index sites in the lower 10 miles of the Stehekin River. Results will be used to evaluate progress towards restoration of adfluvial/fluvial westslope cutthroat trout and management efforts directed at reduction of non-native rainbow trout in the lower 8 miles of the Stehekin River (see Section 2.2.3).
