Abstract: Water samples were collected from three lakes that were chemically rehabilitated in 1986 by the Province of British Columbia, Ministry of Environment, Recreational Fisheries Branch. Samples were analyzed for rotenone and the Noxfish diluent to determine both persistence and rate of detoxification. Results indicated that both rotenone and the Noxfish diluent were essentially nondetectable in water samples taken 7 months after fall treatments. The rates at which rotenone became nondetectable ranged from 17 to at least 77 days. The Noxfish diluent reappeared after some period of absence in two lakes including detection the following spring. It was recommended that routine water sampling occur where waters are used for domestic purposes and that monitoring programs similar to this be continued and expanded to cover other piscicide formulations as used. Further programs to determine inert ingredient dissipation rates, pathways within lake systems for uptake and release of inert ingredients, and toxicity of inert i
