The water was waviii at the surface, having’ a temperature of SC^, and was some- 
what stained from the presence of vegetation. The temperature near its outlet, in 14 
feet of water, was 74°; in 22 feet of water, 07°; nearer the center of tlie lake, in 25 
feet of water, 61°; near the uj)i)er end, in 25 feet of water, 52°, This last measure- 
ment was probably near springs. On the west side, near the middle of the lake, in 
water 25 feet deep, the tenqierature was 01°; jiear by, in 22 feet of water, it was 02°. 
At a spring back in the woods a short distance on the east shore the temperature 
was about 51°. There are undoubtedly many springs in the bottom and the lake is 
mostly supplied from that source, 
CEDAR CREEK. 
Cedar Creek rises a short distance above Indian Lake, and after llowing through 
that lake and Cedar Lake it continues in a southeasterly direction and Hows into the 
St, Joseph liiver at Cedarville, in. Allen County, Ind. 
Cedar Creek was hshed, July 15, at a point 14 miles above Cedar Lake. Here it 
has an average width of about 10 feet, an average depth of 8 indies, but with a slow 
rate of current. The bottom is mostly mud, but gravelly on the lilhes. 
Cedar Creek was examined from the outlet at Cedar Lake down to a point 2 miles 
below Waterloo, a distance of about 7 miles, July 17 and 18. The first 2 miles from 
the lake down the channel has been ditched and straightened so that the water has 
an average depth of about 10 inches. In the remainder of the course examined the 
channel is very crooked, with many deep holes and frequent gravelly shoals. At the 
outlet of Cedar Lake this creek had a width of 12 feet, an average depth of 10 inches; 
rate of current of one-third foot per second. Cedar Lake at this time, therefore, dis- 
charged 1,500 gallons of water per minute. Temperature at the bottom of this water, 
08°; in the air at 0 a. m., 76°. 
At several places the channel has much driftwood which obstructs the jiassage 
of tish, and it should therefore be removed. During floods the bottom lands are said 
to overflow to a dejith of 2 feet. 
In the channel were found algrn {Hostoc and 8pirogi/ra), lizardtail in full bloom, 
diti.'h grass, and marsh cress. On the banks wmre seen ground ivy, purple vervain, 
button bush, horseweed, bulrushes, common thistle, teasel, elder, yellow dock, horsetail 
[Equisetce], and numerous willows, 
MILL CREEK. 
Mill Creek, a few miles southeast of Indian Lake, July 15: This little stream wms 
fished , lust below Mr. Wert’s mill pond, of which it is the outlet. It has but a small 
current. The bottom is gravel or mud and the water is wnirm and not Amry clean. 
This stream empties into Cedar Creek. 
ST. MARYS RIVER. 
St. Marys Eiver is formed by the confluence of several creeks in the southern jiart 
of Auglaize County, Ohio, After a northwesterly course through Mercer and Van 
Wert counties it enters Indiana and crosses Adams County and tio'A^'S to Fort Wayne 
in Allen County, Avhere it joins the St. Joseph Eiver. It has no lar,ge tributaries. 
It was investigated at the following places: i 
The St. Marys Eiver was examined immediately above the city of St. Marys, in 
Auglaize County, Ohio, August 3. The channel has an average width of about 30 
feet. The banks are 7 or 8 feet high. The current is mostly sluggish. We found only 
one riffle, and on this the Avater Avas contracted into a stream 5 feet wide and only a
