In the mid 1990s BC Hydro began operating Hugh L. Keenleyside (HLK) Dam to reduce dewatering of Mountain Whitefish and Rainbow Trout eggs.
The primary goal of the Lower Columbia River Fish Population Indexing program is to answer two key management questions:
What are the abundance, growth rate, survival rate, body condition, age distribution, and spatial distribution of subadult and adult Whitefish, Rainbow Trout, and Walleye in the Lower Columbia River?
What is the effect of inter-annual variability in the Whitefish and Rainbow Trout flow regimes on the abundance, growth rate, survival rate, body condition, and spatial distribution of subadult and adult Whitefish, Rainbow Trout, and Walleye in the Lower Columbia River?
The inter-annual variability in the Whitefish and Rainbow Trout flow regimes was quantified in terms of the percent egg dewatering as greater flow variability is associated with more egg stranding.

Quesnel Lake supports a recreational fishery for large Bull Trout, Lake Trout and Rainbow Trout. To provide information on the natural and fishing mortality, trout were caught by angling and tagged with acoustic transmitters and/or reward tags.

The key management questions to be addressed by the analyses are:
Other objectives include the estimation of species richness, species diversity (evenness) and the modeling of environmental-fish metric relationships and scale age data. The year-round minimum flow was implemented in the winter of 2010 at the same time that a fifth turbine was added.

Water chemistry, periphyton growth, invertebrate and fish data were collected from Curtis and Qua Creeks during 2015-16 to assess their productivity. The fish data were collected by two or three pass depletion electrofishing.

The large, piscivorous Gerrard Rainbow Trout of Kootenay Lake support an important recreational fishery. Intermittently, since 1966, length, weight, fecundity and scale information has been collected from individual fish.
The primary questions the following analyses attempt to answer are:
What is the relationship between fork length and a) weight and b) fecundity?
How does body condition vary by year?
How does growth vary by year?
In addition the analysis asks
Are trends in growth and condition related to trends in kokanee abundance?
