178 THE HYDROGKAPHY OF ST. JIARY'S COUNTY 



is a marsh. The effects of ordinary tide extend a short distance above 

 the highway bridge at Cliaptico. The banks of the stream are low and 

 subject to overiiow during high water. The velocity of the current is 

 generally quite rapid until tide-water is reached. The discharge on 

 July 9, 1904, was measured by current meter by E. J. Taylor at a point 

 about one-half mile above the highway bridge near Chaptico, and found 

 to be 12 second feet. 



ST. CLE.MEXT RIVEE. 



St. Clement Eiver has a total drainage area of 23 square miles. Its 

 basin has a gentle, even slope and is almost flat in the lower part; on 

 the higher part there are several farms, but near the stream the land 

 is marshy and is covered with underbrush and timber. Below the high- 

 way bridge, at Clements, the basin is one large marsh. The effects of 

 ordinary tide extend nearly to this bridge. The velocitj' of the current 

 is rapid in the upper part of the stream, becoming sluggish as it strikes 

 tide-water. The discharge on July 11, 1904, was measured by current 

 meter by E. J. Taylor and found to be G.G second feet. 



MCINTOSH RUN. 



Mcintosh Kun, wliich has a total drainage area of 26 square miles, 

 empties into Breton Bay, near Leonardtown. Its basin is mostly timber 

 land, with farms along the tops of the divides. The banks of the stream 

 are low, heavily wooded and subject to overflow for almost the entire 

 length of the stream. The bed is full of old logs and drift wood. In 

 the upper part, the velocity of the current is generally rapid, while in 

 the lower part the water stands in long, deep pools, with swift shoals 

 between. At the head of Breton Bay, the stream flows into a marsh. 

 The discharge on July 11, 1904, was measured by current meter by 

 E. J. Taylor at the highway bridge, about one mile above Leonardtown, 

 and found to be 4.7 second feet.
