Louis Creek, a known North Thompson River coho and chinook spawning tributary, was studied jointly by the Fish Habitat Improvement Section and Department of Fisheries and Oceans in mid-August 1981. The major objective was to identify the potential salmon enhancement opportunities and benefits with consideration given to low summer flows. The study was conducted by standard low-flow fish habitat and carrying capacity analysis. The salmonid population was composed primarily of rainbow trout and coho salmon juveniles up to saturation levels with fewer numbers of chinook salmon and Dolly Varden char. High but not exceptional abundance of coho juveniles was observed near known spawning areas. Highest fish abundance was allied with the uppermost reaches which tended to be less affected by water abstraction due to excessive irrigation demand. Fish habitat was found to be of reasonably high quality and probability-of-use standards demonstrate a large, vacant spawning and rearing environment, particularly for salmon.
