The purpose of the study has been to evaluate the present management practices, and to develop more efficient techniques for providing trout fishing in coastal lakes. The initial results of this study were reported by Hansen2. The latest phase of the study has been the release of equal numbers of equivalent size cutthroat trout and rainbow trout, Sa.lmo gairdneri gairdneri Richardson, to compare the survival, growth, and return to the angler of the two species. The total catch of each of numerous plants of cutthroat trout has been estimated through the use of a creel sampling program. The tendency of planted cutthroat trout to migrate downstream has been monitored at a weir on the Munsel Lake outlet. The weir has been in operation each migratory period since April, 1962.
