BULLETIN OF THE UNITED STATES FISH COMMISSION. 
and straighteued, but below this the channel is very crooked, swinging from side to 
side across the bottom land. The bluffs bordering the bottom lands are at some places 
20 to 25 feet high. The creek was examined for a distance of 2 miles from its source 
down. The bottom is mostly sand; at some places it is covered with coarse gravel or 
rocks, while in the woodland the bottom is mnd. The current is rapid, and the depth 
of water was nowhere more than 4 feet. 
Everywhere in shallow water the bottom of the channel is covered with water- 
weeds and algm. Lizardtail is the commonest plant along the water’s edge. Several 
service-berry trees were.uoticed upon the banks. 
Fish Creek was again examined near Edgerton, Williams County, Ohio, July 28. 
One mile north of Edgerton, where the.investigations were made, this stream was 20 
to 25 feet wide, and the.clay banks had a height of about* 5 feet. The bottom of the 
channel is also of clay and tvhere not covered with sand or gravel is very slipiiery. 
The water, on account of recent rams, had a yellowish color. The stream is almost 
free from vegetation. 
BIG RUN. 
Big Eun, near Butler, Ind., July 29: One mile north of Butler, where this stream 
was examined, it had a current on the riffles about 3 feet wide and not more than 3 
inches deep. Thei'e are several stretches of quiet water, which had a depth of 3 to 4 
feet, and contained many bullheads and small-mouthed black bass. One of the latter 
weighed half a pound. The bottom is clay or mud and notably clear of vegetation. 
Big Eun has its origin among large springs 8 or 10 miles northwest of this iilace, 
and, after flowing southeast some 5 or 6 miles, empties iuto the St. Joseph Eiver. 
INDIAN LAKE. 
Indian Lake, near Waterloo, Ind., July 15 : This body of water lies 12 miles north- 
west of Waterloo. It has a length, east and west, of one-half to three-fourths miles 
and IS about one-eighth mile- wide. In most places the shores are lined with Nuphar 
and Nympluea, MyriophiiUum^ Chara, and algie. Its banks are marly on the north 
side, muck elsewdiere. 
Mr. Anthony Zonker measured the lake some years ago and found it 45 feet deep at 
its upper eud, which agrees with our measurements. The depth near the lower end 
was 00 feet. Further toward the center, 28 feet, with a bottom temjierature of 55°. 
At about tlie middle the depth was 55 feet, with a temperature of 48°. 
Indian Lake is fed by a small stream which enters from the north, and its outlet 
is a sluggish ditch at the east eud. 
CEDAR LAKE. 
Cedar Lake, 4^ miles northwest of Waterloo, Indiana, July 14: This lake has a 
length of about half a mile from north to south, and is one-eighth of a mile wide. 
Formerly it was perhaps a third larger, but its area has been decreased by ditching 
the outlet. There is muck bottom everywhere. Cedar Creek, the outlet, has some 
gravel. The lake is margined with marsh, the water’s edge is filled with lily pads, 
mostly N^(phar, also Nymphcm in abundance, Potamogeton, Myriopliyllum^ and various 
algae. Lenma is very abundant. The laud around the lake is timbered with, in order 
of abundance, beech, gray ash, ironwood, slippery elm, dogwood, hawthorn, white oak, 
red oak, cherry, hickory. There are many willows at the lower end of the lake.
