An emergency LAMSBD board meeting was held with Dr. Haller

An emergency LAMSBD board meeting was held with Dr. Haller hydrilla expert from the University of Florida.  (Click here for Dr. Haller's follow-up letter.)  Considering his recommendations and after consulting with the Mac Tech engineers, the board slowly lowered North Lake by 6 feet and herbicide treatment will be applied in two stages--two weeks apart.

The lower level of the lake provides a good opportunity for inspecting and repairing the overflow valves.  Photo by Stibolt. The experts inspect the overflow tube.  Photo by Stibolt.

Aquathol K were applied to North Lake

the herbicide was pumped into the boat from the dam. Photo by StiboltTwo large containers of Aquathol K were applied to North Lake.  Charles Aquatics used two ultra-light air boats to navigate the shallows since the lake is drawn down.Both Dr. Haller and the representative from the herbicide company were on hand to monitor the application.  The whole process took several hours.  

 

 

 

 

 

 

 

 

 

The hydrilla will start to die with a week and by two weeks, it should be completely knocked down.

Calibrating the oxygen monitor.

Also an oxygen monitor was calibrated so we'll be able to monitor the oxygen levels on a regular basis and bring in more water from South Lake to add oxygen if we need it.This treatment (and the drying in the shallow areas) will kill the vegetative part of the plant, not the tubers. It will come back, but hopefully the carp will be waiting for it as it resprouts.

Bryozoans

These large gelatinous masses you might have seen in the lake are colonies of bryozoans. They are related to coral and are good for the lake because they absorb extra nutrients. They will dry up as the water turns colder and start again in the spring. Here's a link with more information: www.millermicro.com/bryozoa.html.
