Chronology of 2022-2023 Rice Lake Winter Aeration project
November 13, 2022 - Winter Aeration signs posted along shoreline
In preparation for the winter aeration later this season, signs were posted at various entry points to the lake reminding everyone that winter aeration will be conducted on the lake which will mean there will be areas of open water present. Please use caution when venturing out onto the lake once winter aeration begins.

Site Preparation for Winter Aeration
Since the City replaced some of the storm drain adjacent to the aerator last winter, some erosion has occurred between the system unit and the shoreline. RLAA volunteer installed some gravel in that area to help stabilize the aeration slab and motor housing.
City service request #31103 has been opened requesting the City to install fill underneath the aerator PVC and alongside their storm sewer pipe to help prevent erosion.
Service Request #31103
We (Rice Lake Area Association) would like to thank the Public Works department for removing the large boulder from the top of the aeration system PVC/air hoses last month. The original work was done in late fall of 2021 when the storm drain was replaced and the boulder left on top of the PVC/air hoses.
The area below the PVC and alongside the storm drain has since been eroded and would greatly benefit from installing some fill to reduce future erosion. RLAA installed 4 bags of small rock today (11/8) around the aeration unit and under the PVC up to the shoreline, but it would be very helpful to have more fill installed (see attached photo). Can the City install fill beneath the remaining PVC out to the water and alongside the storm drain pipe before this winter?
As of today, no response on this request.
