Lake Mendota open for trout fishing April 6

Spring trout fishing season opens April 6 in Illinois.

SPRINGFIELD – The 2019 Illinois Spring Trout fishing season opens on Saturday, April 6 at 58 ponds, lakes and streams throughout the state, with four new sites added for this spring. Baumann Lake in Cherry Valley is among the sites that have been added for the first time for spring stockings.

Lake Mendota is once again a participant site in the spring trout fishing program.

The Illinois Catchable Trout Program is funded by those who use the program through the sale of Inland Trout Stamps. The IDNR stocks more than 80,000 rainbow trout each year in bodies of water where trout fishing is permitted during the spring season and an additional 80,000 trout for the fall season.

No trout may be taken from any of the stocked sites from March 15 until the spring trout season opens at 5 a.m. on April 6. Anyone attempting to take (harvest) trout before the legal harvest season opening will be issued citations.

All anglers must have a fishing license and an Inland Trout Stamp, unless they are under the age of 16, blind or disabled, or are an Illinois resident on leave from active duty in the Armed Forces. The daily catch limit for each angler is five trout.
