Job completion report ;

Twenty-three lakes and seven streams were surveyed during the report period. Twenty-one of the lakes were mountain lakes surveyed using a helicopter as the equipment and personnel carrier. Two lakes were follow-up surveys. An opening day creel census was made on Browns Lake and Georgetown Lake. Five streams were checked by electrofishing. Three of these were to evaluate stream improvement structures, one to secure information prior to mine dredging, and one to obtain background information for the Rock Creek Creel Census. One lake and four streams in the Bitterroot drainage were sampled to collect fish for analysis of residues of DDT and its metabolites
