Lake Weeds Summer 2012

From Kay Botko re: spring 2012 inquiry on status of Bryant Lake

After chatting with a number of neighbors and learning of our collective concern about the condition of the condition of our lake - the quality of the water, the numbers of dead fish, and th incredible layers of weeds seemingly choking off areas of the lake, I decided to track down someone who might give us some answers.

Finding a "real person" to talk to was no small task, as I was shunted from Three Rivers employees, to Highland Park, to "that number is no longer in use" to a litany of extensions that didn't deal with such issues.  Finally, a nice gal in charge at highland's offices of Three Rivers directed me to Rich Braich (he is the fellow quoted in today's paper regarding lakes/algae growth/water quality in the Twin Cities.  He principally deals with Water Resources (763-694-2061) and is not reachable but does return calls.  I called, explained my concerns and awaited an answer.

He was fairly prompt in his response, and in fact mentioned that in the interim he was in the process of dispatching a sampling crew to Bryant Lake, so he called their attention to my inquiry regarding the east side of the lake.  This testing crew apparently tests the water of the lajke every two weeks.  Their testing has shown that the quality of the water is not only very clear, but has a good quality of oxygen levels in the water.  The water had received an alium(?) treatment earlier and all of the data indicates that the quality of the lake water is very good.  They keep records of this data relative to state standards and it would be available should anyone want to see it.

It seems that the vegetation condition of the lake is what is causing the greatest concern for the residents as we see whole bays virtually impassable to the boat traffic.  He was aware that it is principally the Eurasian milfoil that is the culprit.  There is also a broadleaf plant, whose name I couldn't recall, coontail, and pikeweed-both of which are good for fish habitat.

Historically, residents have taken care of their frontage-in various ways:  pellets, approved chemical spraying and divers "weeding" the lakefront.  Our park does chemically treat the weedy areas when they encroach on the beach.

I mentioned that of particular concern also was the inordinate number of dead fish last week.  He said that a certain number of dead pan fish is an annual occurance-nothing out of the ordinary.  When I mentioned that we had, however, seen a number of larger fish, bass, and a huge muskie....he said that that would be of concern to the DNR and would prompt their further inquiry.

Apparently at issue also is:  Is this current heavy weed problem an anolomy?  Something that happens once every ten or twenty years?  (Some basis on climate change indication, as well as an incredibly unusual winter and early spring growing season)  Or, is this the: " new normal".  We may have to manage the symptoms or agree to harvest.  It may require group action if it continues.  What is the role of the Three Rivers District?  The DNR?   Well...those are the fellows that I hven't been able to reach.

It was suggested that a guy by the name of Kevin Bigalke is the guy to talk to and he is on vacation until June 18th.  It was also suggested that the DNR at Shakopee is the place to call.  We need to talk to Darryl Ellison at 952-496-4141, extension #222 for further information.  He doesn't answer, but I was assured that he will return the call.

NOTE:  I don't know of the accuracy of my "recall" on this conversation, so don't quote it as gospel.  Rich was very nice, spent almost 20 minuttes with me, so this is a "capsule'.  We need to follow up.
