BULLETIN OF THE UNITED STATES FISH COMMISSION. 
The Tiffin River was fished at a point 6 miles southeast of West Unity, Ohio, 
July 27. Here the river is about 40 feet wide; the almost perpendicular banks are 
from G to 9 feet high and expose bluish clay with strata of gravel. The bed of the 
channel is also clay and full of snags, making it very difficult seining. The Tiffin 
is mostly a sluggish stream with a maximum depth of G feet. The water was roily 
from recent rains. Width of stream, 38 feet; average depth, 9 inches; rate of current, 
U3 feet per second. This gives a flow of 1G,G00 gallons of water per minute. The 
temperature of water at a depth of 3 feet was 80^, The bottom land at this place is 
broad and fertile and not so rolling as higher up the stream. 
The Tiffin River was next examined at Brunersburg, a small village 2 miles north- 
west of Hetiance, Heflance County, Ohio, August 48. The bottom of the river is of 
limestone (Devonian), and along the banks are outcrops of shale. The banks of the 
river are about 10 feet high, and the bluffs bordering the bottom land are 20 to 25 feet 
high. From the bridge at Brunersburg down to the mouth of the river, a distance of 
2 miles, the water has an average depth of about 3 feet and but little current. At 
Brunersburg below the old dam are broad riffles overgrown with weeds. At the 
bridge, one-fourth of a mile above the mouth of the river, the channel is 204 feet wide. 
AUGLAIZE RIVER. 
The Auglaize River is formed in the south west part of Allen County, Ohio. It 
flows iirst southwest through the city of Wapakoneta; thence northerly through 
Allen, Putnam, and Paulding counties. At Deliance, in Deliance County, it empties 
into the Maumee River 1 mile below and opposite tlie mouth of the Tiffin River. The 
Auglaize River differs from the other branches of the Maumee River in having 
numerous important tributaries. The most important of these are the Blanchard 
River, Sugar and Hoaglin creeks. Each of these streams was examined. 
The Auglaize River was examined at Wapakoneta, Ohio, August 4. At this place 
the river has a varying width of 40 to 80 feet, with banks 5 feet high. The solid bed 
of the river is smooth, but occasionally covered with loose rocks and near the city 
with tin cans and other refuse. The current is mostly sluggish ; few riffles. The channel 
in shallow water is thicklj’ covered with riverweed. There are also occasional patches 
of xiondweed and algrn. Many willows skirt the stream and overhang the water. 
The Auglaize River was investigated near Cloverdale, Putnam County, Oldo, 
August 9 and 40. Here the stream was examined from the mouth of Sugar Creek 
down to that of the Blanchard River, a distance of 4^ miles. The width of the 
Auglaize River just before receiving Sugar Creek is 74 feet, and Sugar Creek at its 
mouth is 80 feet wide. The Auglaize River below their junction has a width of 405 
feet. While Sugar Creek has somewhat the wider channel, the Auglaize had the 
greater volume of water. Auglaize River, 4^ miles below the mouth of Sugar Creek, 
receives the Blanchard River from the east. The Auglaize and Blanchard rivers were 
both measured immediately above their confluence and each was found to be 449 feet 
wide, and each had an average depth of about 45 inches, Neither of these streams, 
by the nature of their confluence, offers advantages over the other to the xiassage of 
fish. Just below the junction of the two rivers the Auglaize has a width of 440 feet. 
Here the temperature at the bottom of 5 feet of water was 7G°; near the surface, 79°; 
in the air, 94°.
