Stream Permitting Reminders

Just a quick reminder to our readers that if they have to do any work that affects the bed or banks of a stream in Lewis and Clark County, a permit from the Conservation District–among others–is probably necessary!  This includes the run of the Missouri River Reservoirs, Canyon Ferry, Hauser and Holter reservoirs.

If you don’t know if this applies to you, please contact us and we can help you avoid a violation of state law and possible fines.

Any private, non-governmental individual or corporation that proposes to work in or near a stream on private or public land must apply for a 310 permit.

The person conducting the work should submit a completed application to the conservation district office. The District will determine whether the planned activity requires a 310 permit and if so, will set up a team inspection. The Supervisors will approve, modify or deny the permit application. The process takes about 30-60 days.

Applications are available on our Stream Permitting page.  There is no fee for a 310 permit.

The purpose of the 310 permit program is to minimize soil erosion and sedimentation, maintain water quality and stream channel integrity, and prevent private property damage to adjacent landowners.

Permit applicants may receive planning assistance from the local Conservation District, Natural Resources Conservation Service and the Department of Fish, Wildlife and Parks.

For more information or to determine if you need to apply, contact the Lewis & Clark Conservation District office at 449-5000 ext. 3884 or 3886. You can e-mail us at chris@lewisandclarkcd.org or connor@lewisandclarkcd.org. Emailed applications are acceptable. The office address is 790 Colleen Street, Helena Mt. 59601.
