Courtney and Corbett Lakes were selected for treatment with the fish toxicant, rotenone, because much of their potential trout production was diverted into maintenance of large numbers of redside shiners (Richardsonius balteatus). The treament was scheduled for early October 1973, and to evaluate its effects, observations were made on both lakes in May and September 1973, and in May and September 1974. The objective was to assess changes in plankton and bottom organisms as some concern had been expressed that the treatment might have deleterious and lasting effects.
