This is an innovative proposal for enhancing kokanee spawning in some shore areas in Lake Pend Oreille, in the face of winter drawdowns. Although constructed spawning platforms have been used elsewhere, this proposal is innovative in that the platforms are cleanable to remove accumulated silt. However, the effectiveness of the artificial substrate for solving the overall problem of lack of target adult kokanee abundance is not fully persuasive, for other limiting factors besides spawning are likely limiting kokanee production in Lake Pend Oreille - e.g., hatchery fish are released with unsuccessful results.
The portable characteristics are especially innovative. The technique, if proven successful, would be applicable to Lake Roosevelt, which has similar problems. All aspects appear technically sound and do-able. The cost is reasonable for the work to be accomplished. However, it would have been nice to have seen this approach already field-tested with a small prototype before plunging in at this scale.
Despite some reservations, the Panel ranked this proposal at 20.
