    Fishing Permits

    A Hidden Lakes permit is needed to fish at Hidden Lakes. All adults age 16 and older are required to have a Hidden Lakes permit. Permits are valid from April 1 to March 31 of the following year. Revenue generated from annual permit fees goes directly to stocking a variety of fish into the lakes. The State of Illinois no longer requires state licenses to fish at Hidden Lakes Historic Trout Farm.

    Note: Hidden Oaks staff and the public will not be given dates to when the lakes will be stocked as stocking occurs on a random schedule correlating with the sale of annual permits.
