Algae in Lakes - 8/20/2014
Update from Tony Staup
We have experienced an outbreak of bright green planktonic algae. Many lakes are experiencing the same issue which is consistent with the high temperatures.
It is possible this algae could be a blue green algae. The only indicator is the algae may eventually demonstrate a blue green (not bright green) hue. Left untreated the blue green could be potentially dangerous to animals and humans. The danger is from consuming a large amount of water directly touching the bloom. It could be life threatening to a small dog and or make a small child sick.
The danger is from direct consumption at the bloom point, not out in the general lake. Just use common sense and you will be OK. We are treating the bright green blooms with a chemical called Seclear, which is the recommended treatment with the recommended dosage. Once the water cools, either by ambient temp or rainfall the algae will die.
We are not in eminent danger by any means, just be cautious not to drink the water on or around the visible blooms. Please report any further outbreaks to Chuck Higgins or to any SID board member.
The following infomation was provided by SID Chairman Tony Staup. The SID Board would like to have feedback from RSL homeowners. The SID Board will respond, at least on a monthly basis. Tony has volunteered to attend morning or evening coffee discussions. These informal informational meetings will have open dialog and a question and answer format. Any resident interested in hosting a coffee either AM or PM, please contact Tony Staup, 402-578-2330 firstname.lastname@example.org with a proposed time and place.
Tony is available to do these coffee meetings once a week, as time is available. Tony has been involved in virtually every formal meeting, either in person or on the phone since the inception of the lakes water projects.
Q. What happened to the idea of lake dredging?
A. Dredging is still on the table for the fishing lake. The SID Board expects to address this issue later this year or early next year. The Board must first perform a study to determine the cost and effectiveness of the process.
Q. If Alum capsulates the phosphorus, then why do you have to treat the lake?
A. The alum treatments only dealt with the existing phosphorus in the lakes. Phosphorus is continually introduced to the water with wells, rain, and ground water. This will be an ongoing process. The alum flock does create a residual effect of Phosphorus, and will gradually reduce the needed strength of additional treatments.
Q. What are the long term effects of Alum treatment? Do continued treatments pose any increased health risk?
A. Alum does not present a health risk. This process is an old and tried process for treating water, including drinking water. The long term effects of alum will gradually decrease the strength and frequency of treatments, and create a minor compression effect on the bottom of the lakes.
Q. Does the alum treatment reduce the “sludge” and increase the depth of the lakes.
A. No, Alum only effects the phosphorus not the sludge. The sludge is being addressed with a chemical experiment, and long term will probably have to be addressed with dredging. It is possible to see a very minor increase in the depth of the lakes due to the compression effect of the flock created by the combination of phosphorus and alum.
Q. Is it true the phosphorus levels are better in the well water than the ground water?
A. The very short answer to this question is Yes, but I do believe we need to clarify the answer.
Obviously, we have a real problem from both our wells and ground water. The SID Board is in the process of determining the best cost scenario for phosphorus mitigation.
Q. What is the monthly cost of operating the wells?
A. The electrical cost is in the neighborhood of $400 per month per well. The ongoing maintence is roughly $195 for inspections every 2- 3 years and the resulting fixes from the inspections of $0 to $5000. The higher number is rare.
Q. How much does the recirculation study, and water treatment study cost?
A. We have not determined the cost of the recirculation study. This is new information to us, and the SID Board is investigating.
