Rainbow Trout rear in the Lardeau and Lower Duncan rivers. Since 2006 (with the exception of 2015) annual spring snorkel surveys have been conducted to estimate the abundance and distribution of age-1 Rainbow Trout. From 2006 to 2010 the surveys were conducted at fixed index sites. Since 2011 fish observations have been mapped to the river based on their spatial coordinates as recorded by GPS.

The Kaslo River and Keen Creek, which is a tributary of the Kaslo River, are important Bull Trout spawning and rearing tributaries on Kootenay Lake. From 2012 to 2020, field crews have night-snorkeled these systems in the fall and recorded all juvenile Bull Trout less than 350 mm in length. Keen Creek was not snorkelled in 2020 due to visibility issues. Snorkel and electrofishing marking crews have also captured and tagged juvenile Bull Trout for the snorkel crews to resight. Redd counts have been conducted in both systems since 2006, with the exception of 2020, in which Keen Creek was not surveyed. The primary goal of the current analyses is to answer the following questions:

Invertebrate and fish data were collected from Curtis and Qua Creeks from 2015 to 2017, water chemistry data were collected from 2015 to 2018, and periphyton data were collected in 2015, 2016 and 2018 to assess their productivity. The fish data were collected by depletion electrofishing.
