Alberta Fish and Wildlife has received a complaint that 150 coyote carcasses were dumped on public lands surrounding a reservoir in southern Alberta.

Spokesman Brenden Cox said the complaint came from a member of the public who made the discovery on March 2 at the Milk River Ridge reservoir, about 44 kilometres southeast of Lethbridge.

Cox said it is legal to hunt coyotes year-round without a licence, as long as it's not done on unoccupied forested public lands where hunting coyotes is only permitted during the hunting season.

He said the animals found in the reservoir were likely hunted and trapped legally.

Cox said there are concerns about the improper disposal of waste on public land, which is an offence under the Environmental Protection Act and carries a $250 fine.
