SIMPLIFYING MONTANA’S PERMIT APPLICATION PROCESS
Gilly makes Montana’s stream permitting process easier to understand, helping you complete your application and keep your project information organized.
DO YOU NEED A PERMIT?
Stream-related work in Montana may require one or more permits depending on the project, location and type of applicant.
If you are a private individual or nongovernmental entity planning work that will physically alter or modify the bed or banks of a perennial-flowing stream*, Montana law requires a 310 Permit.
*A perennial-flowing stream normally has flowing water throughout the year, during both dry and wet years.
