The bottom is princij^ally of mud and muck with only a ver^' 

 small area covered with gravel. There are great beds of submerged 

 plants at each end and along the sides, while water lilies are 

 abundant in the numerous bays. 



Although the bottom temperatures are low enough for brook 

 trout, the bottom water has a strong odor of hydrogen sulphide, 

 an indication that it is deficient in oxygen. The lake now con- 

 tains large-mouthed bass, pickerel, yellow perch, sunfish and bull- 

 heads for which it seems best adapted. 



Crystal lake is only about .5 of a mile long and .15 of a mile 

 wide. On its east shore is situated "Scouthaven", a summer camp 

 for boy scouts. The greatest depth recorded was 27 feet. The 

 bottom is composed ])rincipally of mud with only an occasional 

 area of gravel. Pond lilies are abundant and large submerged 

 meadows of pond weeds, water weeds and wild celery occur at each 

 end. Althougli the lake has been repeatedly stocked with small- 

 mouthed bass, the predominating form is the large-mouthed and 

 this species together with bluegills and calico bass should be 

 planted in the future. 



flava lake has a minimum depth of about 25 feet and is fed 

 principally by springs located in the north^vest corner. The bot- 

 tom temperatures were low ranging from 58.5 to 62. Mud bot- 

 tom predominates everywhere except for a sliort stretch along the 

 nortliwest shore. Su])mei'ged vegetation is dense and extensive 

 wliilc patclies of poud lilies were found here and there in the 

 shallows. 



The bottom water is cold enough for trout but there is evidence 

 of hydrogen sulphide which is an indication that the oxygen con- 

 tent is too low. Doctor Leffingwell seined the lake carefully and 

 found the following species among others: yellow perch, bullhead, 

 pike-perch, large-mouthed bass, northern pike and sunfish. It has 

 been stocked with small-moutlied bass but none was seen and pre- 

 sumably the i)hnit was not a success. The geueral conditions seem 

 much better suited to a large-mouthed ba.ss and associated forms.
