RECLAIMING MUCK LAND

depth of a little more than s 1 ^ feet at the 

 outlet. If open ditch was used, about 7 feet 

 at the outlet would be necessary. With an 

 allowance of i to i 1 /^ feet for the depth of 

 water in the outlet ditch, it is evident that 

 6 l /2 feet is minimum depth for tile outlet and 

 8 to 8% feet for the outlet where open later- 

 als are used. A ditch 3 feet wide at the 

 bottom, 6 feet deep, and 15 feet wide at the 

 top is the smallest that has a right to be 

 called an outlet ditch under any conditions.

Ditches shallower than this are for surface 

 water primarily and a depth of 2 to 3 feet 

 is sufficient.
