E Canyon Res was a lake at one time that was maintained with kokanee and my first time trolling for them in 1977. By about 1992 time frame the kokanee population had fizzled out with the lake taken off off the stock list. I had heard a couple of rumors of what had happened and hoping someone will pipe in with the story. In 2019 there was a stock of over 10,000 kokanee and another more recent in April 2020 of near 17,000.
