4. Fish Populations in Artificial Lakes. 



The principal emphasis this year will be on evaluating the changes in fish abundance 

 and growth in Lake Ahquabi in which turbidity has been greatly decreased. Re- 

 search will also be continued on other artificial lakes in which population changes 

 are being studied. 



Indianola, Iowa; State Conservation Commission cooperating; began June 1948, con- 

 tinuing; $4,500; quarterly progress reports (mimeographed) available for limited 

 distribution.

5. Effect of Dredging on Fish and Fish Food Organisms in Shallow Prairie Lakes. 



This study is aimed at the evaluation of changes in fish populations and fish food 

 organism production before and aiter dredging operations. Bottom fauna studies 

 are emphasized. Improvement of conditions for boating and recreation and re- 

 duction in winter kill of fishes are the objectives of the dredging. 



North Twin and Lizard Lakes, Munson, and Little Wall Lake, Jewell, Iowa; State 

 Conservation Commission cooperating; began May 1951, continuing; $3,000; 

 quarterly reports (mimeographed) are available for limited distribution.

6. Population Studies on Walleye Pike in Clear Lake, Iowa. 



This project is part of a long-term investigation of fish population changes in Clear 

 Lake. It includes extensive tagging during spawning run, followed by creel 

 census and experimental gill netting to estimate population, rate of exploitation, 

 and mortality rates. Fry plantings have been made in alternate years since 

 1948 to test value of such propogation. Data are collected on all species to de- 

 termine population dynamics. 



State Conservation Commission cooperating; began June 1947, continuing; $5,000; 



quarterly progress reports (mimeographed) available for limited distribution.

1. Montgomery County State Lake Project (FA: F-l-L). 



This is the first of several projects planned for the purpose of creating new 4akes. 

 An area of 410 acres of land in Montgomery County is being acquired. This will 

 be followed by a project for the construction of a dam to impound 105 acres of 

 water on the above tract.
