2. Classification of Public Lands 



This project is designed to survey State and Federal lands in Montana and 

 to classify these according to their present and potential values for access to 

 fishing waters. Every effc-t will then be made to have these lands withheld 

 from sale. 



Statewide; began July 1952, indefinite; $7,200; Clinton G. Bishop, Leader; 

 reports available. 



Address inquiries to: Clinton G. Bishop, as in No. 1 above. 



3. Cataloging the Lakes and Streams of Montana 



The purpose of this project is to determine by modified measures of 

 standard procedure the chemical, physical, and biological characteristics of 

 the waters of the State. Coverage of the greater portion of the waters is to be 

 superficial with the greatest effort being placed on those waters which are most 

 important to recreational fishing. Depending upon the water involved, qualita- 

 tive and/or quantitative measures of trout stream populations are made by 

 electric fish census methods. 



Statewide; began April 1951, indefinite; Frank Stefanich, Nels Thoreson, 

 Boyd Opheim, Arthur Whitney, and Perry Nelson, Leaders; reports available. 



Address inquiries to: Montana State Department of Fish and Game, 

 Mitchell Building, Helena, Montana. 



4. A Limnological Survey of the Three Forks Ponds Before and After the Applica- 

 tion of Toxicants 



A limnological survey is to be conducted on three cold water ponds approxi- 

 mately two miles east of Three Forks, Montana. These ponds are similar in area 

 (approximately 20 acres) and lie adjacent to one another. Two of these ponds 

 are now known to contain various species of warm and cold water fishes. 



The limnological study will be carried on for one year and then a different 

 commercial toxicant will be applied to each pond. The investigation will be 

 continued for an additional year. The objective is to study the effects of these 

 toxicants on the limnology of cold water ponds and to determine their period 

 of toxicity and effectiveness in killing various species of fish and fish food 

 organisms. Several ponds of similar size and characteristics are repaorted to 

 be in the same area. A general survey will be made to determine which of these 

 nnaintain fish populations. Those with obnoxious fish will be rehabilitated with 

 various toxicants and the period of toxicity and success of the fish kill will be 

 determined.

5. Effectiveness of Smith Lake Rearing Pond 



The primary objectives are to measure the actxxal production of Smith 

 Lake as received from a known number of fry cutthroat trout planted and to 

 determine the economics of the operation considering the cost of operation 

 and the value of the yearling fish produced. 



Flathead Coxinty; began June 1950, to close April 1957; $700; Frank A. 

 Stefanich, Leader. 



Address inquiries to: Frank A. Stefanich, Route 7, Box 50-B, Kalispell,
