Lord knows the recent fisheries management work at Wehrspann Reservoir in west Omaha has been THE topic of discussion this week.  I want to add this update. . . . Our field biologists that did the treatment went back today to see how things looked.  As you can imagine they discovered hundreds of thousands of dead shad.  How many?  I cannot tell you an exact number or even an estimate.  But, there are photos floating around the internet and here …

The last time I blogged about Lake Yankton was to inform folks about the rotenone renovation that was being …

Let me share some more of what we know about that fisheries …

Watts Lake Renovation

Our Nebraska Game & Parks fisheries personnel had an opportunity to get another quick renovation done this spring.  There have been some news releases on this, but I am guessing many folks may have not heard about it.  Here is an extended version of the news release, a version with a little more detail on why these projects are so beneficial: Watts Lake Renovated to Improve Fishery Recently the US Fish and Wildlife Service and Nebraska Game and Parks Commission(NGPC) renovated …

Rat and Beaver

I hate to keep hitting the same topic over and over again.  I know I blogged about the Lake Yankton renovation a couple times in recent weeks (Lake Yankton Renovation ,  Lake Yankton Renovation, Postscript), but I want to tell you about another rotenone renovation that Nebraska fisheries biologists completed recently. Late summer and early fall is definitely “renovation season”.  Typically, water levels are lower at that time of year and less water means we need less rotenone to treat the volume …
