DI^AINAGE INVESTIGATIONS. 45 



tho imindntion of Lvon Swnnip. He also preioared a plan for the 

 drainage of the swamp comprising G.OOO acres. 



A survey has been made by H. A. Kipp to determine the work 

 necessary for ])rotecting against annual overflow and draining the 

 bottom lands of the Tuscumbia Kiver, in Prentiss and Alcorn coun- 

 ties, Miss., amounting to 23.000 acres. 



The report of D. G. Miller, giving plans for levees to protect from 

 overflow lands in Kichland County, 8. C, on the Congaree Kiver, 

 below Columbia, has been revised to provide against floods equal 

 to that of 11)08, and has been transmitted to the landowners most 

 interested. 



DRAINAGE OF IRRIGATED LANDS. 



The work of drainage investigations in tho irrigated lands of Utah 

 and Colorado has been done under the supervision of C. F. Brown, 

 who has been assisted by R. A. Hart, D. G. Miller, and H. R. Elliott. 

 Many localities have been examined and drainage ])lans outlined. 

 Surveys have been made, and the construction of the drains Avatched 

 and directed, in order to study the movement of the water in the soil 

 and to learn how it can best be intercepted or removed. Such surveys 

 have been made of several new tracts in Utah. Plans were prepared 

 for a district of 1,000 acres near Venice, and examinations were made 

 of injured fruit lands in the (Jreen Kiver Valley near Vernal. On 

 the tracts in Emery and Washington counties, where previous efi'orts 

 of this Office have been but partially successful, further studies are 

 being conducted. 



Plans have been made for the drainage of a number of tracts in 

 western Colorado in the vicinity of Grand Junction, Delta, and 

 Montrose. The drains are installed by the landowners, and the 

 injured areas are being reclaimed in almost every instance. A drain- 

 age survey was made of the California Mesa, near Delta, showing 

 the areas needing drainage, and general plans will be made for 

 imj)roving these lands and preventing further injury. The investi- 

 gations in the San Luis Valley have been continued, where the interest 

 in drainage is rapiiUy increasing. 



C. (i. Elliott visited Yakima County, Wash., to examine the 

 Wajjato irrigation project in company with the Reclamation Service 

 eiigineer.s. A drainage plan was submitted to the Department of the 

 Interior for reclaiming the 43,000 acres of this project now injured 

 by .seepage and alkali, and for keej^ing other lands from being 

 affected. 



L. L. Hidinger has nuule investigations of conditions in {\\v Kio 

 (irandc ^^llley in Texas, where the need of drainage is being forced 

 upon the attention of all people interested in agriculture. Low areas 

 have become saturated with water from higher irrigated land, and in
