The Minnesota Department of Natural Resources is getting annoyed with the number of bottles, cans and other garbage that's being left on area lakes.
But the Department says identifying the perpetrators is the biggest problem.
Ken Soring, Enforcement manager for the northeast region says wind can also make it difficult to prove where the trash come from and there's not enough Conservation officers to thoroughly enforce litter laws.
Litter is a petty misdemeanour criminal charge in Minnesota with a fine of up to 300-dollars.
