Panel of Lake Management Experts Discussion- 11/11/17 NJ COLA Member's Meeting [Summary provided below by Alan Fedeli, COLA Board of Trustees member and Moderator for Panel discussion]
I was honored to moderate the expert panel discussion at the NJ COLA Membership meeting held on 11/11/17. We had 60 lake association members in attendance, and the exchange of ideas was excellent.
Panelists: Fred Lubnow, Princeton Hydro; Chris Hanlon, Aquatic Technology; Bob Schindler, Solitude: and Larry Kovar, Aquatic Analysts
Trend is to use less copper and in lower doses since copper sulphate spawns more blue green algae.
Chelated Copper: Chelated copper is effective on both filamentous and planktonic algae in a wide range of fresh water applications. Upon application, it starts to work immediately and works extremely well—it’s far more effective than copper sulfate. When applied, it stays active (suspended in the water column) longer, rather than immediately sinking to the bottom. This allows you to use less copper, and take a more precise route to dealing with the problem.
Harmful Algae Blooms (HABs); Extensive discussion on increased emphasis on detecting and reacting to HABs.
Abraxis Strips: A quick way to test for cyanotoxins. Algae blooms are occurring more often, and more extensively, each year, in fresh water.
Blue Dye: Benefits of shading out UV rays using blue dye was discussed.
1. Systems don’t need to be failing to contribute phosphorus into lakes.
2. Any system 50 years old and 300 feet from the lake is contributing phosphorus.
3. Regular pumping, (e.g., 3 years) can reduce phosphorus loading by 20 to 30% (Lubnow)
Important to continuously monitor for algal conditions to anticipate blooms. Once blooms start, it is too late.
We were able to get confirmation from the panel that an undersized aeration system can in fact lead to mixing without maintaining sufficient dissolved oxygen.
It was pointed out that geese poop on average 28 times a day, although the intern who followed these geese around to get the count remains nameless.
