IX.— THE TURKEY RIVER. 
The Turkey River at Elkport flows through a much broken country. Its current is 
strong and its bottom sandy or rocky, with very little mud. In this region the river 
is bordered in many places by cliffs. Its temperature was 74° E. 
Bear Creek is a spring brook, which has a temperature of 65° E. It also flows 
through a very broken region. In several large springs near the creek the tempera- 
ture was 50° E. Some trout were planted in the creek a few years ago, but they have 
not been seen since. 
At Fort Atkinson the Turkey River has a sandy bottom and flows through a much 
less heavily timbered and uneven country than at Elkport. 
The Y olga River is a large tributary of the Turkey, which at Fayette has a sandy 
bottom with a few rocks and little mud. Its temperature was 70° F.
