242 Lake Maxinkuckee, Physical and Biological Survey 



July 11, 2:00 to 4:45 p.m. Stations 91 to 110. Air 84; 

 water 81 to 84; sky cloudy, showery late in evening; depth 3 

 feet and under; 45-foot seine. Began at Norris's pier and pro- 

 ceeded up the east side to the McOuat cottage. For most of this 

 distance the bottom is of sand and fine gravel, usually covered with 

 a matting of Chara. In many places, stones, old tin cans, broken 

 bottles and the like made seining difficult. 



Catch: Bluegill, 925; log perch, 190; skipjack, very many; 

 small-mouth bass, 40 ; straw bass, 17 ; yellow perch, 101 ; rock bass, 

 45; grayback minnow, 17; pumpkinseed, 4; yellow cat, 1; silver- 

 side, 1; and blunt-nose minnow, 1. 



The bluegill was by far the most abundant fish taken, 419 being 

 in haul 109. Young skipjacks were very common, especially in 

 hauls, 93, 104 and 106. The log perch was remarkably abundant, 

 58, 51, 40 and 64 being taken in hauls 101, 105, 107 and 110, re- 

 spectively. 



In the last few hauls the water appeared roily, caused chiefly 

 by the presence of much plankton, crustaceans and algse. 



July 12, 2:15 to 4:10 p.m. Stations 111 to 120. Air 87; 

 water 79 to 89. These stations were in Norris Inlet. Begin- 

 ning at the bridge where the road crosses, stations 111 to 117 fol- 

 lowed up the creek to the heavy woods about its head, while sta- 

 tions 118 to 120 were from the bridge down stream until the creek 

 became lost in boggy ground. Seine, 15-foot. 



Catch: Straw bass, 79; bluegill, 22; mud minnow, 17; grass 

 pike, 35 ; creek chub, 8 ; pumpkinseed, 4 ; and dogfish, 3. The straw 

 bass were all young, as were also most of the grass pike. The 

 bottom was usually black soil, sand or decaying peaty matter. In 

 shallow stagnant places the water was very warm. 



July 13, 1:45 to 2:55 p.m. Stations 121 to 131. Air 86; 

 water 76 to 80 ; depth 5 feet and under. Same ground seined 

 over July 5, stations 1 to 11, but under different atmospheric con- 

 ditions. A storm came from the northwest and swept across the 

 north end of the lake while the work was in progress. Some rain 

 fell and strong waves came in from the north. 



Catch : Bluegill, 331 ; yellow perch, about 325 ; rock bass, 52 ; 

 grayback minnow, 35 ; log perch, 28 ; small-mouth bass, 13 ; straw 

 bass, 7 ; pumpkinseed, 6 ; Johnny darter, 3 ; hog sucker, 1 ; yellow 

 cat, 1 ; blunt-nose minnow, 3. In haul 129, which was through a 

 thick patch of Scirpus americanus, young rock bass were very 

 abundant, 28 being caught. Young yellow perch and bluegills also 

 were abundant. 



July 17, 1 :30 to 3 :40 p. m. Stations 132 to 147, from the end
