I know that my lake association takes responsibility for managing weeds in the lake but my landing still has problems with weeds. Is there anything the neighbors can do to manage the weeds in front of our properties?
Up to My Neck
Dear Up to My Neck,
Great question! There are many options you can consider to help tame the weeds. First you might consider small-scale physical intervention around your own pier or property. You can remove up to 625 square feet (i.e.. 25’ x 25’) of nuisance weeds without a permit from the IDNR. Two options are a weed rake or a weed roller. If you and your neighbors want to treat a larger area, then chemical treatment by a certified aquatic herbicide applicator may be in order.
These professionals will apply for an IDNR permit, which must take into consideration the total number of acres treated across the lake for the season. While an overabundance of weeds are a nuisance to many lake residents, native aquatic plants are important for the health of the lake and life under the surface. You should also check with your lake association in the spring/early summer to see if they have an updated aquatic plant management plan and to view their priority weed treatment maps for the year.
Remember, the best long-term solution is to be proactive! TWF takes action to stop the pollution that causes weeds and algae growth. You can help by reducing your sediment and nutrients inputs.
Use phosphorus-free lawn fertilizer or none at all.
Don’t feed the waterfowl. Their poo is fowl too.
Don’t pickup hitchhikers. Clean your boat and trailer of all weeds before moving from lake to lake.
Use glacial stones and/or native plants in front of your seawall or instead of a concrete seawall.
Maintain your septic system and support community sewer projects.
