Mantua Reservoir

Latest fishing report

The reservoir is capped with 10 to 15 inches of ice with three inches of snow on top. Please use extreme caution as the ice conditions continue to change. Fishing is fair in the morning and slows in the afternoon. Anglers are catching planter-sized rainbow trout and small perch. Try using ice flies and small jigs tipped with mealworms. There are road closures at the reservoir for the Mantua East Spring Re-Piping Project. While the work continues, access to the south side of the dike road will be closed. The Public Works Administrative Office will notify the public when access reopens. If you have questions about the project, please call 435-734-6615. (Last update 02-22-19)
