These activities are not allowed on this stream:

Alterations of the stream bed

• Stream channel alterations are prohibited except those necessary to maintain and improve existing utilities, roadways, diversion works, fishery enhancement facilities and managed stream access facilities; for the maintenance of private property; for new water diversion works; and for public agencies to construct public access facilities and fishery enhancement facilities. In addition, new private stream access facilities may be allowed with Idaho Water Resource Board approval.

Construction of Water Diversion works

• New diversion works shall be limited to installations which have the main riverbed structure located below the water level and blended with the riverbed or to pumping installations which do not create an obstruction in the river, and are visually blended with the surroundings so as to be less noticeable from the river; are provided with fish screens if appropriate; and which receive the aesthetic and fish screen design approval of the Idaho Department of Water Resources.

Special considerations:

Where the designation of a state protected river precludes a project or development, the Board will consider requests from individuals to amend a component of the comprehensive state water plan on a case-by-case basis. P. 162.
