218 IRRIGATION INVESTIGATIONS IN UTAH. Through the aid of Mr. James McArthur, water master for the St. George^and Washington Field, complete crop return data were gathered for the purpose of showing the money value of the water carried by the canal. A total of 1,660 acres was watered, planted to crops as follows: Alfalfa, 1,342.5 acres; wheat, 194.5 acres; corn, 40.5 acres; oats, 19 acres; sorghum, 17.5 acres; barley, 11.5 acres; fruits, vegetables, etc., 34.5 acres. Alfalfa received an average of .6.9 waterings between April 8 and October 6, and yielded an average of 3.40 tons per acre. Wheat received an average of 3.3 waterings between April 17 and June 25, and yielded an average of 27.46 bushels per acre. Oats received an average of 3.7 waterings between April 20 and June 17, and yielded an average of 35.78 bushels pef acre. Barley received an average of 3.2 waterings between April 17 and June 25, and yielded an average of 27.46 bushels per acre. After the alfalfa crop was harvested the meadow furnished pasturage valued at $3,131. The total return from the 1,660 acres was $37,113, or an average per acre of $22.36. The return per acre-foot of water artificially applied was $3.10. . ..•'• JABVI8 HKLD. The Jarvis Field lies oa the right bank of Virgin River, 2 miles southeast of St. George, and is the next field below the St. George and Washington Field. The Jarvis Ditch leaves the river on the right bank through a cut in a rock ledge, has a width of 5 feet, and when full, carries water to a depth of 1/5 feet. May 13, 1902, 30 feet below the lowest sand gate and about 100 feet below the dam, it was carrying 14.84 cubic feet per second, which approximates the usual high-water flow. During 1902 about 200 acres were being irrigated from the ditch. The Jarvis Ditch was started in 1865, and for the first few years watered between 200 and 300 acres. At one time, about 1874, 500 acres were watered* On June 15, 1880, the Jarvis, Cooper, Bottom, Seep, arid Virgin ditches, the latter then known as the Rio Virgin North Oanal, were united in the Rio Virgin Canal Company on the theory that the Rio Virgin North Canal, if properly managed, could, in dry seasons, be made to better cover the land formerly covered by the three ditehce. This arrangement continued for three years, during which time it was demonstrated that the Rio Virgin North Canal could not cover the three fields. Thereupon the Jarvis and Seep ditches again became separate, and the Rio Virgin North Canal wa« abandoned. The annual assessment for care and maintenance of the Jarvis dam and ditcfc is from $1.50 to $2 per acre. SANTA CLARA SKSP DITCtt. The Santa Clara Seep Ditch diverts the water that passes the upper dams in Santa Clara Creek or returns to the creek in seepage from the fields above. It heads in Santa Clara Creek near the lower end of the St. George Clara fields, and waters 214 acres on the lower Santa Clara bottoms north of Virgin River and west of the Jarvis Field. This ditch is controlled by the Santa Clara Seep Ditch Company, which was incorporated January 6, 1896, with a capital stock of 244 shares of water right, of the par value of $25 each. The 214 acres watered is owned by 20 irrigators, whose average holdings are 10.7 acres. Each acre receives water from one and one-half to two hours each watering, the waterings occurring every fifteen or
