The ISRP concludes that, while this proposal addresses a potentially important factor limiting abundance of trout in the San Poil River, the approach using radio telemetry of adult fish and searching for groundwater refuges is unlikely to yield information that is critical to management decisions concerning trout habitat. A much stronger approach would be to focus on age-0 trout as they enter their first winter – their distribution, habitat requirements, their movement (if any) to find those habitats, and their survival. This would enable the Colville Confederated Tribes to identify specific stream reaches that are important for preservation and possibly restoration. A revised proposal is needed that: a) better establishes the current status of the trout resources in the San Poil, identifying the information needed to develop management actions to remediate winter habitat bottlenecks b) includes age-0 fish abundance and early winter habitat use in the proposed survey c) discusses more fully the role of groundwater expected in the San Poil system and re-examine the scope and effort to be expended d) provides the needed site description, maps, genetic analysis, etc. e) more fully describes the proposed visual and video surveys relevant to task 2.1 if they remain as part of the proposal f) explains how movement data from radio-telemetry of 15 adults per life-history type can provide adequate information for making critical management decisions.
