[2] The north-east portion of the lake–on the east side of McCormick Bay–is designated as Fishing Lake Wildlife Refuge.

[4] Record floods in 2007[5] resulted in a plan by the Government of Saskatchewan to lower the level of the lake by digging a drainage channel.

Local volunteers worked at developing Leslie Beach, and in 1967 the Fishing Lake Regional Park Authority was established.

Leslie Beach, the main part of the park, is along the southern shore of the lake alongside the resort village of the same name.

Besides the replica fish, Leslie Beach also has a campground that has 116 seasonal campsites, 51 daily sites, and washroom and shower facilities.

KC Beach, named for the Knights of Columbus,[12] is at the south-eastern shore of the lake, and it has a convenience store and boat launch.
