Projects That Do Not Require Permits
Lakeshore owners do not need a permit to cut or pull submerged
vegetation in a small area for swimming or boat docking. A channel 15'
wide extending to open water may be harvested in water lilies without a
APM permit. Anything greater requires an AM permit. The channel is no
more than 15 feet wide and takes the most direct route to open water, is
maintained by cutting or pulling, and remains in the same location from
year to year. Anything greater will require an APM permit.
Emergent vegetation may not be removed without a permit under
2,500 Square feet of submerged vegetation maybe harvested
without a permit provided that the cut does not extend more than 50 feet
along shore or 1/2 the owners frontage whichever is less. If access to
open water is not obtained, a channel 15 feet wide can be cut to open
All vegetation that is cut must be removed from the lake and
disposed of above the "ordinary high water level."
Excavation of bottom materials is not allowed, no lily pad roots

• If possible, avoid wading or swimming in shallow areas near shore.
• Do not feed waterfowl at you property.
If non-chemical measures are ineffective, swimmer's itch can sometimes
