DRAINAGE MODIFICATIONS IN KNOX, LICKING 

 AND COSHOCTON COUNTIES. ' 



By W. Blair Clark. 



It is not intended in this article to discuss the whole drain- 

 age system of these three counties, or even that of any one of 

 them. The area to be studied may be bounded roughly by the 

 triangle whose vertices are located at Newark, Mt. V'ernon and 

 Coshocton. This territory is entirely within the hydrographic 

 basin of the Muskingum and practically all its drainage is carried 

 to that river by three streams. 



The largest of these three streams is the Walhonding 

 River which, with its upper continuation, Owl Creek, flows 

 along the northern side of the triangle outlined above. This 

 drainage axis is the outlet for all the northwestern and northern 

 portions of the region under consideration. In addition, the 

 Walhonding receives very considerable contributions from the 

 North, chiefly by way of Mohican and Kilbuck Creeks. With 

 the exception of the lower part of the former, these two creeks 

 were not studied in this investigation. 



South ol the Walhonding is Wakatomaka Creek, second in 

 order of the three streams indicated above not only in location 

 but in size as well. The axis of this creek takes a general 

 southeasterly direction through the heart of the area under re- 

 v'iew. It drains, perhaps, rather more than a third of the tri- 

 angle. 



Lastly, the Rocky Fork is a small creek confined almost 

 exclusively to the northeastern part of Licking County, and 

 draining quite approximately that whole section of the county, 

 an exception being found along the extreme eastern border 

 which is drained by the Wakatomaka. 



A clearer idea of the relations of these streams may be had 



^ Presented to the Department of Geology and Botany of Denison Univeis- 

 ity as a Thesis in pursuing work for the degree of Master of Science.
