This weekend's catch-and-release fishing programs for children at Wolf Lake State Fish Hatchery in Mattawan have been cancelled due to heat-related stress on fish.
The state says in a release that Saturday's program will be replaced with clinics on casting and knot tying from 8-10 a.m.
Hatchery interpreter Shana Ramsey says fish in the Show Pond are "showing signs of extreme stress" due to the high summer temperatures. Staff will monitor conditions in the pond. Fishing programs on July 27-28 will resume if conditions improve.
The hatchery in Van Buren County will remain open for other regularly scheduled programs and tours.
