THE IERIGATION AGE. 



operated during the month. No breaks occurred and the 

 water supply was sufficient. The amount of water diverted 

 into the main canal varied from 1,130 to 1,285 second-feet. 

 Water was delivered to about 650 users. About 45,000 acres 

 of land were under cultivation, including about 10,000 acres 

 of old alfalfa land, but no wild hay land. On the first 

 division of the main canal and in the first and second lateral 

 districts no construction work was done, and the engineering 

 work consisted of stream gaging and minor work. In the 

 third lateral district contracts were awarded for the excava- 

 tion of about 63,000 cubic yards on laterals 28a to 33 main 

 and work was commenced. Work on the high line canal was 

 continued, all schedules excepting 37 and 38 being completed. 

 Work was also continued on the excavation of lateral 28. 

 Force account work was in progress on dam 15/2, West Win- 

 ter Creek siphon, and several minor structures. Plans and 

 specifications were under preparation for dams 1, 2 and 3 

 and for control works for the same. On Goshen Park and 

 Fort Laramie units the preparation of estimates and the drill- 

 ing at the Guernsey dam site were continued. At the Path- 

 finder reservoir the hauling of sand for use next fall jn con- 

 crete at the south tunnel was in progress and the work was 

 practically finished. On June 26 the reservoir contained 380,- 

 000 acre-feet of water. 



Nevada, Truckee-Carson Project. At Lahontan dam 

 construction work included steam shovel excavation in the 

 foundation trench for the outlet conduit and for the left 

 spillway. At the forebay for the power plant the placing of 

 concrete lining and the construction of the headwall and the 

 penstock headworks were continued. Excavation for the 

 cableway tower tracks was completed and work pre- 

 paratory to the installation of plant was carried on. About 

 160 men and GO head of stock were employed throughout the 

 month. The distribution system was operated throughout the 

 month, supplying a large demand for irrigation water. Both 

 rivers were in flood condition, but no material damage re- 

 sulted. Due to the unseasonably cool weather during May, 

 crops were retarded two or three weeks at the beginning of 

 the month, but warm weather set in during June and crops 

 made good progress in growth. Sugar beets and potatoes 

 were planted to a considerable extent. 



New Mexico, Carlsbad Project {completed). Heavy 

 rains occurred during the month. A small flood in the 

 vicinity of Cass Draw damaged the canal banks and neces- 

 sitated' the placing of about 600 cubic yards of earth to repair 

 the damage. On June 11 water was turned out of the canal 

 for twelve days to kill moss and weeds. George B. Richard- 

 son, geologist, visited the project on June 11 to investigate 

 a third reservoir site, as proposed by the water users' asso- 

 ciation ; no report upon this has as yet been received. Seventy 

 carloads of alfalfa have been shipped from the project and a 

 considerable quantity has been stored by the farmers. 



New Mexico, Hondo Project (completed). Considerable 

 land was irrigated during the month and the first crop of 

 alfalfa was cut. At the end of the month there was no water 

 in the reservoir. 



Nerv Mexico-Texas, Rio Grande Project (preliminary 

 work; Leasburg unit completed). Work at Elephant Butte 

 was carried on during the month with satisfactory progress. 

 Tracks and switches were laid in the terminal yards, leveling 

 for the cable towers was continued, and work on the perma- 

 nent Engle road was carried on. The construction of the 

 flume was continued with good progress. Three derricks were 

 received for this work and were set up. Telephone communi- 

 cation was extended over the works, more cottages were built 

 for the mechanics, and the headquarters mess was about com- 

 pleted. Work was continued on the hospital building, corral 

 building at the lower townsite, and officers' quarters. The 

 erection of the bridge over the river by contract was prac- 

 tically completed. The supervising engineer spent three days 

 at Elephant Butte and the chief electrical engineer has been 

 in consultation with the contractor who is to erect the power 

 plant. Forty-five carloads of materials and supplies and eleven . 

 local shipments were received over the railroad during the 

 month. Canal surveys between Las Cruces, New Mexico, and 

 El Paso, Texas, were commenced. 



On the Leasburg unit operation and maintenance was con- 

 tinued. The river was in flood during the month, with a dis- 

 charge of from 2,000 to 5,000 second-feet. A small cloudburst 

 occurred near the head of the Leasburg canal and consider- 

 able sand and gravel was washed into the canal from small 

 arroyos. About 300 cubic yards of material were removed in 

 making the necessary repairs. 



North Dakota, Missouri River Pumping Project (Buford- 

 Trenton unit 38 per cent completed; Williston unit 64 per 

 cent completed). The Missouri River rose about 6 feet dur- 

 ing the month. The precipitation amounted to 1.23 inches. 

 The land owners under the Buford-Trenton unit met the re- 

 quirements of the secretary's order of May 13, and operation 

 was started June 20, water deliveries being made to six farm 

 units. On the Williston unit operation was commenced June 

 3, water deliveries being made to 52 farm units. About 5,000 

 acres of land, nearly all of which were under cultivation, were 

 entitled to delivery of water. Crops under irrigation are in 

 excellent condition, and the cutting of the first crop of alfalfa 

 was well under way. 



Oregon, Umatilla Project. Weather conditions were 

 favorable except for strong and persistent winds. The maxi- 

 mum temperature was 102 and the minimum 36 F. The 

 delivery of water to the reservoir ceased June 17, and the 

 lining of portions of the feed canal was begun. The total 

 quantity of water diverted from the river through the feed 

 canal during the month was 4,700 acre-feet, of which 3,200 

 acre-feet reached the reservoir. Nine thousand five hundred 

 acre-feet of water were turned out from the reservoir to the 

 distribution system, and 1,500 acre-feet were diverted from 

 the river through the Maxwell canal. The available storage 

 in the reservoir at the end of the month amounted to 41,000 

 acre- feet. At the end of the month water-right applications 

 had been received covering 12,675 acres of land. 



Oregon-California, Klamath Project (45 per cent com- 

 pleted). Crops are looking well, except in places where high 

 winds have blown the soil over part of the grain. Water 

 service was continued throughout the project without unusual 

 incident, and water was turned into the Ankeny canal about 

 June 27. The force at work on Lost River diversion channel, 

 schedules 2, 3 and 4, was increasad, and had nearly reached 

 the schedule requirements by the end of June. Work on 

 Schedule 1 was continued with satisfactory progress. Good 

 progress was made on concrete work at the Lost River diver- 

 sion dam, foundations for about one-third of the piers, the 

 upstream cut-off wall, and portions of the heavy retaining 

 walls on the north side of the river being completed. The 

 contractor had two barges in use on the main canal freight- 

 ing sand, cement, etc., from the railroad siding to a point on 

 the East Branch canal two miles from his work. This water 

 transportation has greatly facilitated the handling of freight. 

 The cut-off trench under the south embankment has been ex- 

 cavated to solid material and has been refilled about to the 

 elevation of the original surface. Excavation of the drain 

 with the Lidgerwood excavator was continued with some- 

 what better progress than during May. The preparation of 

 estimates and contract drawings for Poe Valley, Griffith and 

 Nuss laterals was nearly completed. Surveys were made for 

 several minor drains in the first unit. The elevations of the 

 water surface in Clear Lake and in Tule Lake slowly receded 

 during the month. On two occasions water was turned from 

 Clear Lake into Lost River for irrigation of lands in the 

 upper Langell Valley, pending the adjudication of water 

 rights in the locality. 



South Dakota, Belle Fourche Project (89 per cent com- 

 pleted). Labor and weather conditions were favorable for 

 construction work during the month, but on account of the 

 extreme dryness the weather was unfavorable for crops. At 

 Belle Fourche dam 500 square yards of block paving were 

 placed -during the month, the entire paving being completed 

 on June 8. Three hundred and seventy-five linear feet of 

 parapet wall were built and 1,300 cubic yards of gravel placed 

 on the top of the dam. All of the main construction work 

 on the dam was completed on June 15, the balance of the 

 month being utilized in finishing ragged ends and cleaning 

 up. The construction of the North canal, schedules 1 to 8, by 

 contract was continued with good progress, and approximately 

 10,000 cubic yards of material were excavated by the con- 

 tractors for the townsite lateral. Excellent progress was 

 made by force account on North Canal structures and lateral 

 excavation. About 12,000 acre-feet of water were delivered 

 for irrigation, all of the available water in the reservoir being 

 utilized. 



Utah, Strawberry Valley Project (47 per cent completed). 

 With the exception of considerable rain in the vicinity of 

 Strawberry dam, weather conditions were favorable for con- 

 struction work. At Strawberry tunnel 273 linear feet were 

 excavated during the month, progress being impeded by the 

 water encountered in the heading. The average flow of water 

 from the tunnel continued during the month at between 6
