Frequently asked questions

What is Gilly?

Gilly is a software platform that standardizes and streamlines the 310 Joint Permit Application process for both applicants and administrators. The name Gilly comes from an ancient Gaelic term for a guide on an expedition in the wilderness or on a river. Gilly guides river preservation and restoration.

Do I need a 310 Permit?

Montana's Natural Streambed and Land Preservation Act, also known as the 310 Law, is a state mandate that requires any person planning to work in or near a stream or river on private or public land to obtain a 310 Permit from their local conservation district PRIOR to beginning that work.

The purpose of the 310 Law is to keep rivers and streams in as natural a condition as possible, minimize sedimentation, and recognize beneficial uses. Failure to obtain a 310 permit is a misdemeanor crime, subject to a civil penalty and a fine of up to $500 for each day of unauthorized activity. Additionally, you may be required to restore the damaged stream at your own expense.
