During 1980 and 1981, the Fish Habitat Improvement Section (FHIS) with support of regional staff, undertook a biophysical assessment of the mainstem Nicola River and its major tributaries. Investigations were focussed on the role and relative importance of various components of the watershed for anadramous fish production. Due to the size and complexity of the watershed, it was felt that three consecutive years of data (i.e., an index sampling approach) were required to develop enhancement strategies with reasonable confidence to satisfy fisheries information needs and those of the Ministry of Environment's strategic planning process. Fish population size, biomass, growth rate, and habitat quality and quantity were investigated through detailed habitat description and fish sampling techniques. During the second year of investigation, fish sampling in deep water habitats attempted to assess summer outmigration of chinook and rainbow presmolts through repetitive seining in August and September.
