Comments:
Source is this study. Trost 1993 calls this Chester Hill Reservoir but the coordinates for this was a land-locked area south of Nounan. Chester Hill Reservoir did not turn up anything. Colleen Moulton (IDFG, pers. comm.) suggested this might be Chesterfield Reservoir, and Trost (1985) has Chesterfield Reservoir as a survey site with similar low numbers (<10) so I assumed that and corrected this to Chesterfield Reservoir.
