Abstract
Using otolith and scale methods, age and growth characteristics of kokanee (Oncorhynchus nerka) obtained in 1969 and 1970 from the Helena Valley Reservoir, near Helena, Montana, were calculated. Record kokanee have been observed in these waters. An investigation of migration into and out of the reservoir was made. A brief analysis of kokanee distribution in the lake was included. Creel census data from 1969 and 1970 was incorporated into the study.
