 Help us keep Rainbow Lake healthy and beautiful! Join the RLA for 2025 now!

Early Bird Discount: It’s time to pay your membership dues, and to help out, we are giving an Early Bird Discount!  If you pay before April 1st, dues are $380 Lakefront, $330 Lakeview, and $185 General.  After April 1st, dues go up to $400, $350, and $195 respectively.  So, don’t be an April Fool – pay your dues early and avoid the pay increase!  You can pay online at https://www.rainbowlake.org/membership/ or download the Membership form on the same webpage and pay by check.  Of course, if you pay your dues early, but don’t really need a discount, feel free to add that amount to one of our other projects on the website.

TAG SALE: Last fall, we decided to skip a year for the Tag Sale because the quality of the donations had declined. However, we have had significant interest in doing one sooner than later, so we intend to have one this spring to coincide with everybody’s Spring Cleaning, date TBD.

Phosphorous Reduction Project:  As a reminder, we are in the midst of a Phosphorous Reduction Project that started last spring. Our treatment company, Pond and Lake Connection, applied Eutrosorb, a lanthanum-based material, to strip phosphorous out of the water column and bind it to the sediment. This action should substantially reduce the need to apply herbicides.  We didn’t expect to see aesthetic results last summer, but we definitely did.  Even with the hot summer, we had substantially less algae than we would normally expect. We started the project with Lake Improvement Funds, but will need more to continue this planned three year project. You can donate to the project at https://www.rainbowlake.org/lake-environment/.  

Here’s to a great New Year on the Lake!

Sincerely,
The RLA Board

You may have noticed we have begun our Phosphorous Reduction Project with the application of a product called Phoslock.  This project is a four-year project approved at last year’s Annual General Meeting. 

The major cause of unsightly algae growth on our lake is an excess of phosphorous.  Over the last few years, we have done studies to show that the majority of our phosphorous comes from the lake bottom as opposed to the inlet streams.  Yesterday lanthanum (a natural chemical) embedded in bentonite (a natural clay) was applied to absorb the phosphorous in the water column as well as the lake bottom.  Lower concentrations of phosphorous will, overtime, lead to a healthier lake ecosystem and fewer applications of herbicides.

We have been working directly with the Chief Scientist at the manufacturer of the product who tested our lake to determine the optimum application for our specific lake.  Requests for Proposals to apply the product were sent out and we selected the best bid, which happened to be our current Lake Management team, Pond and Lake Connection.  A discussion of the selection process is on our website (see link below).

While we hope to lessen our future dependence on, and costs of, our normal herbicide applications, this project requires funding.  We have enough in our Lake Improvement Fund to cover the first year of the project (about $40,000), but will need to raise funds to continue.

Dear Neighbors,

We now have public boats! In order to reduce the number of boats on the beaches, the RLA will now have four RLA member boats on Crescent Beach. They have “RLA” stenciled on the side and we have both kayaks and canoes. We will put some life preservers in the beach shed and a few paddles, but we encourage members to bring their own paddles and life preservers. This is the first year we have tried it, and, if successful, we will add some more boats. Please be courteous and return the boats, paddles and life vests to Crescent Beach after use.
