Thoughts from Joel - Fall Leaf Raking
I recently read the procedures on monitoring dissolved oxygen which is part of our lake testing program. Coincidentally, I also ventured through the canal from Round Lake to take a tour on Devil's Lake. I noticed a lot of leaves on the bottom of the canal, and we regularly find leaves on the anchor as we test in the deep part of the lake. These two things combined prompt me to write a small piece on lake health as it relates to leaf raking in the fall. Dissolved oxygen in the water is very important to the lake and is affected by a number of things. Photosynthesis from plant life increased the oxygen along with atmospheric replenishment. As water temperature increased the amount of atmospheric oxygen that can be dissolved in water decreases. Obviously, these are things that we can't control. There is another piece that we can at least help with. Organic matter (leaves, clippings, branches, etc.) that lay on the bottom of the lake use dissolved oxygen in the decaying process. With that in mind, I encourage everyone to rake leaves and keep them out of the water as best they can. Obviously, many will blow into the water directly from the trees, or from the ground before we can rake them, but please do not pile them, burn them on the beach or rake them into the water.
What is the Best Lawn Fertilizer?
In an effort to protect water quality in the area we are asking all residents to consider using no-phosphorous lawn fertilizer. It is estimated that just one pound of phosphorous in the water will produce 500 pounds of blue-green algae. Much of the phosphorus you apply actually runs off the lawn before penetrating the soil. That means that it gets into the lakes and streams contributing to the glue-green algae bloom and the growth of other aquatic plants. Blue-green algae not only stinks but can be toxic to animals and children. When the algae bloom decays, it reduces the oxygen in the water and can cause fish kills. Phosphorus run-off from feed lots, agricultural land and lawns is the main contributor to phosphorus in lakes. The best time to fertilize is May and early June (now). Your lawn does not need phosphorus! Unless you have a newly seeded lawn most soil provides all the phosphorus your established lawn needs.
Attention Round Lake Residents and Fishermen!
The DNR has set up fishnets in Round Lake as of 5/11/2015.
These will be used to count certain types of fish in the lake, primarily panfish. Along with the count some of the fish may be tagged for further education. This will require the cooperation of fishermen who catch a fish with a tag. Instructions are on the tag as to what to do. Please do not boat near the nets for the duration that they are there.
Looking For Some Pictures
Thanks to one of our members for pointing out this interesting article just in time for summer:

State View: How your body wash hurts the Great Lakes
Microbeads, tiny plastic particles, often less than a millimeter in size, are packed into personal hygiene products. Being so tiny, they pass through wastewater treatment systems and end up in rivers, lakes and oceans. Read More...
From the AP John Flesher August 28th, 2014:
“Inadequate regulation of the bait-fish trade and carelessness on the part of anglers may be allowing invasive species – including the feared Asian carp – to reach Great Lakes and inland waterways, according to a scientific paper.”
There is more to this story (Click to read entire article...), but it ultimately comes down to “what can we do?” The answer is …DON’T DUMP LEFTOVER BAIT INTO THE LAKE!!! The LPL has been putting reminders on windshields of cars parked at the public ramp, and plans to post this reminder there for all to see.
Join the Lakes Preservation League!
The lakes are here for all of us to enjoy...but without an organization
committed to lake preservation and improvement, they may not be here for our children.
The quality of life that we have grown accustomed to cannot be taken for granted. Many changes take place that affect our lake environment positively or negatively. We all need an organization that will try to make sure that changes are changes for the better.
Yearly dues are $25.00 (January 1st though December 31st).
Along with your membership you will receive our monthly newsletter, The Preserver, as well as a subscription to The Michigan Riparian which is published quarterly.
