BULLETIN OP^ THE UNITED STATES FISH COMMISSION. 
{g) The Maumee Eiver was examined at Toledo, Ohio, August 25, 26, aud 28. The 
width of this river at the wagon aud street-car bridge is 1,500 feet, and the depth of 
the water at points across the river about 100 feet apart, begiiiniug on the west side, 
was respectively 16 feet, 26 feet, 22i feet, 21 feet, 20^ feet, 17i feet, 12J feet, and 12^ 
feet. The deepest water is under the turu bridge, where the boats pass through. At 
all these places the water had a bottom temiierature of 75°. 
ST. JOSEPH RIVER. 
The St. Joseph River has its rise in the uplands of Hillsdale County, Mich. Its 
general course is southwest through Williams County and the southeast corner of 
Dekalb County, Ind., to Fort Wayne, Alien County, Iiid., where it joins the St. Marys 
River to form the Maumee River. This river was examined at the following places: 
(a) Near Hudson, Mich., July 24: The river was examined at a iioint 6 miles 
southwest of Hudson. Here the stream was fished for a distance of nearly 2 miles. 
The uiiper mile examined flows through woodland, and the bottom of the channel is 
mostly gravel, but at some places mud. There are several large drifts of wood in the 
stream that are barriers to the passage of fish. Further down, the stream flows 
through cleared land and the bottom of the channel is of bluish clay, which has 
eroded very unevenly, leaving many projections and numerous holes. There are many 
long stretches of quiet water, with in some places a depth of 4 feet. Ritfles are few. 
The chaunel has an average width of about 14 feet. The bottom is remarkably clear 
of weeds. The most common plants at the water’s edge are wild touch-me-nots, Joe- 
Pye weed, shrub dogwood, and prickly ash. Owing to the clayey bottom the water 
is not clear. Whgre the volume of water was taken the stream had a width of 10i|^ feet, 
an average depth of 14 inches, and a rate of current of 13 inches per second. This 
gives a volume of about 55,000 gallons per minute. 
The banks of the channel are from 6 to 8 feet high. 
(5) Edgerton, Williams County, Ohio, July 28: The St. Joseph River was seined 
at a point 34 miles southeast of Edgerton. Here the river has a width of 45 to 50 
feet; the almost jierpeudicular banks are 8 to 10 feet high. The bottom of the chaiiuel 
is mostly of sand and gravel with occasional loose rocks. The riffles are few, and 
almost entirely free from weeds. The shores are lined with common weeds, shrubbery, 
and trees. On account of the recent rains the water was tinged with the clay that 
composes a large part of the banks aud bottom of the channel. 
(c) The St. Joseph River was next examined at Fort Wayne, Ind., August 14. 
FISH LAKE. 
Fish Lake, at Hamilton, Steuben County, Iiid., July 19 and 20: What is now 
known as Fish Lake was formerly in three different bodies of water. In 1837 the 
outlet was tilled in and the surface of the lake was thus raised 9 feet, which united the 
three lakes into one body of Avater. The water power of this lake is utilized for milling 
purposes, and is at present controlled by the Fort Wayne Water Power Company. 
Fish Lake has a length, from nortinvest to southeast, of about 3 miles, aud its 
greatest width is about 1 mile. It has several islands, the largest of Avhich contains 
13 acres, the others less than 1 acre each. 
The large island is covered with a growth of small oak. 
That portion of the lake lying west of the large island is known as Feelmke, that 
north and east of it as the Main Lake, and that south of it as the Mill Pond.
