Re: Will I kill 'em?
To pick up on what Jaybo wrote, yes, the constant (or more constant) year round temps from water deep in the reservoir, combine with all the food from it can make tailwaters artificially great fisheries. A quick check of the thermometer in July can tell you for sure on the temps but if the water comes from deep enough in the reservoir it will be minimally impacted by changing surface temps keeping it warmer in the winter and cooler in the summer. Also good fly shops and online fishing reports often include this kind of information in their reports.
