CYPEESS CEEEK DSAIJv^AGE DISTRICT, ARKANSAS. 17 



Lake the chaimel must be cleared, at an estimated cost of S2,000 per 

 mile. In addition, the openings in the 'banks of Bayou Macon must 

 be closed, especially the channel of Little Bayou Macon. The esti- 

 mate for this work, based on meager data, is 35,000 cubic yards at 

 20 cents per yard, or a total expense of $7,000. 



Ditch No. 43. — The soil borings along the proposed route of ditch 

 Xo. 43 show considerable sand from a point near Wells Bayou to 

 Gum Pond, south of Amos Bayou. The depth of flow through this 

 section is therefore made 8 feet and the side slopes 2 to 1. The dif- 

 ference in derations of the Wells Bayou basin and the Coon Bayou 

 basin is 10 feet in a distance of 5^ miles. It was impossible to utilize 

 all of this fall on account of the depth of cut that would be encoun- 

 tered in crossing the banks of Amos Bayou and also on account of the 

 erosion that would occm* from liigh velocities in sandy soil. A 6-foot 

 concrete drop is therefore planned at station 750 (in sec. 36, T. 10 S., 

 R. 3 W.) at an estimated cost of S5,600. An earth dam, estimated 

 cost SI, 000, is planned in Cypress Creek to prevent the water in ditch 

 No. 43 from flo-\ving to the east. At the crossing of Coon Bayou, in 

 the west hue of sec. 19, T. 11 S., E,. 2 W., a solid waste bank should 

 be made on the east to prevent overflow into Coon Bayou. In addi- 

 tion to the small amount of excavation in Cypress Creek, station 430 

 to station 458 (in sec. 36, T. 9 S., R. 3 W.), clearing of channel is esti- 

 mated at SI, 000 per mile. 



AU excavation in this ditch is estimated at 8 cents per yard except 

 that section from station 600 (at lateral No. 34) to station 700 (in 

 sec. 25, T. 10 S., R. 3 W.), which is estimated at 9 cents. The maxi- 

 mum cut in this section is 20.1 feet, on the bank of Amos Bayou, and 

 the side slopes are 2 to 1. 



Ditch No. 81. — The following reaches of ditch No. 81 will require 

 no excavation, but the existing channel must be cleared: From station 

 155 to station 198 (in sec. 33, T. 9 S., R. 2 W., and sec. 4, T. 10 S., 

 R. 2 W.), and from station 447 to station 760 (in sees. 8-31, T. 10 S., 

 R. 1 W.) in Cypress Creek; from station 781 to station 953 (in sees. 

 1-14, T. 11 S", R. 2 W.) in Boggy Cut-off and Boggy Bayou; from 

 station 1080 to station 1151 + 75 (in sec. 26, T. 11 S., R. 2 W.) in 

 Isaacs Lake; and from station 1368 + 50 (in sec. 14, T. 12 S., R. 2. W.) 

 to station 1700 (in sec. 12, T. 13 S., R. 2 W.) in Boggy Lake. All 

 clearing of channel is estimated at $1,000 per mile except in Boggy 

 Lake, where it will be light, and is estimated at $500 per mile. All 

 side sl(j|)es are ('stimated 1 to 1 , and all excavation is estimated at 8 

 cents per cubic yard except the section through Boggy levee, which 

 is estimated at 20 ct^nts. It was assumed that the waste banks were 

 of equul v-olunie on each side? of the existing Clay I>ay()u ditch. In
