[quote Charina]I'm a bit surprised that here in late 2016, there is an angler survey and the appearance of a lack of plan by the DWR. I applaud the survey, but wonder why we are so far behind the downfall of Scofield.
In <a href="http://wildlife.utah.gov/blog/2011/a-strategy-for-scofield/">May 2011, Paul Birdsey</a> indicated that a study was underway, and if appropriate, the DWR would "plan on treating the reservoir in 2014 or 2015."
"The DWR is not just sitting back and waiting to see what happens at Scofield. It is too important a fishery for that approach." How does one reconcile that quote, with the fact that we are still in a decision phase, more than 5 years later?
The number of very large predators needed to make a dent in long-lived adult chub populations means that at this point, we are several years until the tide would begin to shift using predators. Perhaps I'm wrong, but I don't see additional tiger trout walleyes, or wipers regularly gulping down 12-15 inch chub anytime soon. And when they do reach the point, the shift to a healthy balance won't be a quick one.
Rotenone makes the most sense at this point. Large cuts or tigers are good for keeping populations under control, not attacking an out of control population.[/quote]
I think the Southeastern Fisheries Manager wants a feather in his cap for managing Scofield without rotenone.
