Green to Clean project status after two years:

The results of the Green to Clean project are quite favorable.  After applying lanthanum, an organic clay used to trap phosphorus in the sediment, in 2024 and 2025, the scientists studying Rainbow Lake say the water quality is being restored. The releasable phosphorus in the sediment has decreased by half.  It is this releasable phosphorus that causes the unwanted algae growth.

The scientists recommend applying about 25 percent less in 2026 to continue targeting the phosphorus in the sediment. We spent $37000 in 2024 and $36000 in 2025 for those applications, but do not yet have the bid for 2026.

Regardless, our association does not currently have the funds to continue the project in 2026.  The Green to Clean project needs your help.

Introducing the Autumn 2025 RLA Newsletter!

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.
