Rivers & Streams with Special Rules
This section has information on rivers and streams with Special Rules. These rivers and streams have rules that may differ from, or be in addition to, General Fishing Rules for Rivers and Streams.
Turn to the Rivers & Streams With Special Rules section. If you find the waterbody you intend to fish, look immediately beside it for the rules on season dates, bag limits, length limits and methods of taking.
In instances where special limits, seasons, and methods of taking are not noted for a particular river or stream, the General Fishing Rules for Rivers and Streams apply.
In general, rivers and streams are CLOSED TO ALL FISHING from Oct. 16 through Dec. 31, unless specified for a particular river in the Rivers and Streams with Special Rules section.
Fishing through the ice, from the ice, or from any object supported by the ice is prohibited unless specified for a particular river in the Rivers and Streams with Special Rules section.
