The dam Is faced on the lake side with strips of metal roofing and woven wire held 

 In place by metal posts. This has prevented damage by muskrcLLs and ducks. In August;, 

 1938, the dam and spillway were raised 18 Inches, 



The upper half of tne lake and the south shore are screened by a dense fringe of 

 brush and trees. On the slope above the north shore Is a fmlt and nut orchard. No 

 submerged aquatic plants are present In the lake. At one time cattails grew all around 

 the lake shore, but by 1938 there were only a few. Bass have been seen nesting on 

 their roots. Most of the cattails died during low water after the ducks had exposed 

 the roots, allowing them to freeze. 



In the brush on the south side Is a blind for observation, photography or shooting. 

 There Is one boat, 



HISTORY OF FISH POPULATION 



Fish were planted In Fork Lake a number of times before 1938. There are no records 

 of these plantings, but Mr. Smith has furnished the following account from memory-. 



The earliest planting of fish, made In 1920 soon after the lake had filled, con- 

 sisted of shiners, chubs and a few miscellaneous sunflshes collected from nearby streams. 

 In 1921 several hundred largemouth bass, bluegllls and other simflshes were placed In 

 the lake. Four hundred 6- to 7- Inch bass were planted the following year (1922). 

 Shiners and chubs were seined from nearby streams to serve as food for these bass. Bull- 

 heads were first Introduced In 1924 when a school of them was brought In from Flnley 

 Creek. The first crapples were put In this same year. 



During these early years, bass fishing was good* and remained so for three or four 

 years after the original stock had reached legal length. The largest bass taken from 

 the lake during this period weighed 2-1/2 poimds. By 1926 good catches of bullheads 

 were being taken on trotllnes. A summer or two later (1927 or 1928) many large bull- 

 heads died (apparently from lack of oxygen) along with a few shiners and sunflshps. 



In 1932, 100 chaiinel catfish were planted and. In 1934, 32 crapples, 11 to 12 

 Inches long. In 1935, 12 large bass ana a number of bluegllls were added. No stocking 

 has been done since 1935, until in the simmer of 1938, 



In 1935, 8 or 10 large schools of young bullheads were frequently seen swimming 

 near the surface. The bullheads of the 1938 census probably belonged to this large 

 1935 brood. 



Carp and buffalo were never planted Intentionally. It Is possible that they 

 ascended the spillway during high water, or were Introduced accidentally by anglers. 



It Is Interesting to compare the kinds and niimbers of fishes planted with those 

 found when the lake was poisoned. The 32 large crapples planted In 1934 had not oeen 

 taken out on hook and line nor had they been seen dead In the lake. One hundred channel 

 catfish were planted In 1932, The census shows only four channel cats. Although 

 hundreds of bass were planted, the total count was five at the time of the poisoning; 

 The 12 large bass put in three years before were not removed by flshennen nor seen dead 

 along the shore. The fish not accounted for probably died one at a time and were eaten 

 by other fish, crayfishes, turtles, predatory birds or mammals without coming to the 

 attention of occasional visitors to the lake.
