3. Mountain Lakes 



The objectives of this project are to make available for better public use a 

 number of mountain lakes not presently available for recreational use because 

 of the difficulty of access or because of improper or lack of directional or 

 designational signs. About 30 miles of trail, both all-purpose and foot, will 

 be constructed into a wilderness area in the Sawtooth Mountains to provide 

 access for recreational use of the area, including angling use to about 30 lakes. 

 A number of signs will be constructed to help the public find trails to lakes, 

 in both this as well as other areas not marked at the present.
