Water Quality & Fish

Loch Erin is a wonderful all sports lake with great fishing. Our LEPOA board works to ensure we are monitoring both water quality and fish populations to create recreational opportunities for members to enjoy.


Water Quality

Lily Pad and Weed Treatments

Each year, LEPOA limits the number of weed treatments performed on the lake, as there is a theory that less decaying biomass in the lake will decrease the amount of food available to algae, while simultaneously allowing the remaining lily pads to consume nutrients (essentially starving the algae). This decision seems to have been a step in the right direction, as blue-green algae blooms have been minimal.

That said, targeted weed treatments will occur throughout the summer months, focused primarily in the coves and inlets where lily pad concentrations are high. As lily pads are considered native vegetation in Michigan, they can only be sprayed in developed areas where they are inhibiting boat docks and beaches.

Watershed Management Plan

In 2021, the River Raisin Watershed Council, in collaboration with LEPOA, was awarded a research and planning grant from the Michigan Department of Environment, Great Lakes, and Energy. The grant funding, along with a 10% match, will fund a two-year study of the area surrounding Loch Erin and result in a Watershed Management Plan.

Upon completion of the study, suggestions for remediation will be provided to LEPOA and an action plan and path forward can be determined, including potential for additional grant funding requests. Tackling water quality on our lake will be a long, multi-step and multi-year process.

Details were outlined in a Daily Telegram article on February 14, 2022 and can be accessed here.

Shoreline Planting

Shoreline planting, as opposed to grass abuting the lake, helps to consume excess nutrients from entering the lake that would otherwise feed algae. This is an easy step that residents can take on their personal shoreline to help with preserving the water quality on Loch Erin.

A formal Shoreline Planting Committee was created in 2021 to help with shoreline planting at Loch Erin's parks. If you’re interested in volunteering, please reach out to the Water Quality Committee!
