quarter line of the NW. J sec. 9, T. 10 S., R, 4 W.; thence in a general 

 southerly direction, following the west watershed boundary of the 

 district as shown on the map (fig. 3). The district should also 

 include the following land in Chicot County: All that portion of 

 T. 13 S., R. 1 W., lying west of the Mississippi River levee; aUthat 

 portion of sees. 6 and 7, T. 14 S., R. 1 W., lying west of the Mississippi 

 River levee; all of sees. 1, 2, 3, 4, 10, 11, and 12, and those portions of 

 sees. 5, 8, and 9, T. 14 S., R. 2 W., lying east of the west watershed 

 boundary of the district. That part of Drew County, containing 

 8,474 acres, lying east of the district watershed boundary should 

 also be included in the drainage district. With these boundaries, 

 the district would contain 294,784 acres, or 460.6 square miles. 



THE DITCH SYSTEM. 



In planning this system it was of course necessary to keep the 

 sizes of all outlets within the limits of practical construction. For 

 this reason certain diversions were necessary (see fig. 3). 



Wells Bayou, now emptying into Cypress Creek, is diverted in 

 sec. 9, T. 10 S., R. 4 W., by ditch No. 13, flowing into Bayou Macon 

 in sec. 3, T. 12 S., R. 3 W. It is not feasible to divert the water from 

 Wells Bayou into Bayou Bartholomew on account of the high stages 

 that occur in the latter stream, which probably would be considerably 

 increased if Wells Bayou were discharged into it. There is an 

 impression among the local residents that at times Bayou Bartholo- 

 mew discharges considerable water into Wells Bayou through Cross 

 Bayou in T. 9 S., R. 6 W. An examination made at this point on 

 April 3, 1912, on which date occurred the highest stage ever recorded 

 in Bayou Bartholomew, showed only a very small amount of water 

 entering WeUs Bayou from this source. 



The diversion of Cypress Creek is accomplished as follows: First, 

 all that portion above the south hne of sec. 13, T. 9 S., R. 4 W., is 

 diverted at this point by ditch No. 19, flowing directly to Bayou 

 Macon in sec. 18, T. 11 S., R. 3 W. The latter stream is to be im- 

 proved from this point to Macon Lake. Second, ditch No. 43 crosses 

 Cypress Creek in sec. 1, T. 10 S., R. 3 W., which will take the drainage 

 from Oak Log Bayou, now tributary to Cypress Creek, directly south 

 to Macon Lake. Third, by a combmation of channel improvement 

 and ditch No. 81 the drainage tributary to the lower end of Cypress 

 Creek is carried to Macon Lake through Boggy Bayou, Boggy Lake, 

 Clay Bayou, and Clay Bayou Wash. 



The diversion of the greater part of Cypress Creek into Bayou 

 Macon, as noted above, will so raise the level of this stream in the 

 vicinity of the present mouth of Little Bayou Macon that other pro- 

 vision will have to be made for the latter outlet. The drainage tribu- 

 tary to Little Bayou Macon is therefore carried south by ditch No. 18
