State Conservation Commission 



1. Lake and Stream Public Access. (FA: in part) 



Objective of the project is to provide free public access to lakes and streams 

 for angling and other recreational purposes. Acquisition of tracts of land adja- 

 cent to good fishing waters is undertaken whenever they become available. 

 Several areas are in the process of being purchased at this time. 



Statewide; continuing; Lloyd P. Bailey, Leader. 



Address inquiries to: Lester F. Faber, Superintendent of Federal Aid, 

 Division of Fish and Game, East Seventh and Court, Des Moines, Iowa. 



2. Acquisition and Development of Abandoned Strip Coal Mines. (FA in part) 



Current activities consist of development works on three previously acquired 

 areas totaling 758 acres. Fencing of the areas is being connpleted. Partial 

 grading of spoil banks is being done and earth dams and outlet structures for 

 three small lakes are in the process of construction. Tree and shrub plantings 

 are being made, and formerly abused cropland is being seeded to lespedezas 

 and sweet clover. 



Statewide; began 1951, indefinite; Lloyd P. Bailey, Leader. 



Address inquiries to: Lester F. Faber, as in No. 1 above. 



3. Williamson Pond Fisheries Development. (FA: F-IO-D) 



This 26-acre railroad reservoir in the past furnished excellent fishing, but 

 in late years had been unproductive. After acquisition, (FA. F-4-L) it was de- 

 watered as far as was practical by pumping and the fish population destroyed with 

 ennulsified rotenone. 



The spillway in the dam is being repaired and a 10-foot stop-log section is 

 being installed to facilitate drainage should future fish management require it. 

 The pond will be restocked in 1954. 



Lucas County; began September 26, 1953, to close March 31, 1954; $9,000; 

 Lloyd P. Bailey, Leader. 



Address inquiries to: Lester F. Faber, as in No. 1 above. 



4. Blue-green Algae Control. 



Several fish and general recreation lakes of Iowa develop large blooms of 

 blue-green algae which are unsightly and occasionally toxic to waterfowl and 

 domestic animals. Aid of a technical nature is provided to communities or 

 organizations in administering copper sulfate to control these growths. A study 

 of toxic algae is receiving special consideration due to waterfowl losses in the 

 fall of 1952. 



State lakes; began June 1952, continuing; Earl T. Rose, Leader; reports 

 available. 



Address inquiries to: E. B. Speaker, Superintendent of Biology, Division 

 of Fish and Game, East 7th and Court Streets, Des Moines, Iowa. 



5. Natural Lakes Survey. 



All of the natural lakes of Iowa managed for angling are surveyed by the 

 Biology Section each year. This involves test seining with 500 feet of l/4-inch 

 mesh (bar) seine at several stations on each lake. Pound and gill nets are 

 used to supplement the seine catch. The small-nnesh seine hauls are designed 

 to determine primarily the magnitude of reproduction each year, and the nets 

 to determine population fluctuations and status of the adult fishes. Fishes taken 

 are sorted into young-of-the-year and older groups, weighed, measured, and 

 scale samples taken from representatives for age and growth analyses. Data 

 on vegetation, amount of bottom foods (dredge samples) turbidity and lake
