Description: New fields have been created from several sources (Gallatin County, Montana DNRC, City of Bozeman) to make a more comprehensive and descriptive waterways map of the Gallatin Valley. For questions about 310 permits or uncertainty about the NEED_310 attribute field, please contact the Gallatin Conservation District (GCD) at 406.282.4350. The NEED_310 field is a guide, but the ultimate jurisdiction is up to the GCD regarding 310 permits. Applying for a 310 permit is free.
