Idaho’s public trust lands are the lands submerged below the ordinary high water mark of navigable lakes and rivers. Title to these lands is held in trust and is administered for the public benefit. IDL manages these lands to provide for their commercial, navigational, recreational and other uses. Part of that management is administering dock/encroachment permits on Idaho lakes and rivers.
Additionally, the IDL administers ownership of public trust lands along navigable rivers by processing land disclaimers and issuing easements and riverbed leases for commodities such as sand and gravel.

We administer the Idaho Lake Protection Act and regulate encroachments and activities on, in, or above the navigable lakes in the State of Idaho. Encroachments are anything permanently fixed to the lake bed or natural features of the lake bed (such as rocks). Examples of navigational and non navigational encroachments permitted by the IDL include docks, marinas, bridges, utility lines, mooring buoys, and float homes. Authorization and sometimes compensation is required to construct or otherwise use the space above, in, or under the beds of navigable waterways in Idaho.
