PROBLEMS OF.IMPERIAL VALLEY AND VICINITY. 115 Nothing is known of the comparative difficulties of these projects because there are few data on trie two Carey Act projects, but it is presumed the- two latter are the easier, since they were surveyed in 1900 and 1910, respectively, while the Churchs Butte project was not outlined until 1915. CHURCHS BUTTE PROJECT. Acreage, 22,000 net,1 70,000 gross. Precipitation, 65 inches. Annual temperature, 42°. Between frosts (summer), 85 days, average. Transportation, Union Pacific Railroad. Irrigation plan.-Diversion from Blacks Fork section 28, township 17 north, range 16 east; thence along left side of river to irrigable lands lying on both sides of Blacks Fork. HENRYS FORK. Nothing is known of possible extension of irrigation. The discharge of the river based on the record for 1916, which is the only year measured, will average as follows: Acre-feet September-April (inclusive)................................................ 9, 000 May...................................................................... 6, 500 June.................................................................... 6, 500 July..................................................................... 1, 200 A ugust................................................................... 1, 800 Total.............................................................. 25,000 This shows that present rights above the station exhaust the flow after June. One off-stream reservoir, basin site, has been surveyed, but indications are that it will not hold water. Possible extension of irrigation is limited and is placed in the grand total in the summary of irrigated acreage for entire Green River in Wyoming. HAMS FORK, OPAL PROJECT. Acreage: Gross, 70,000; net, 50,000. Other statistics same as for Churchs Butte project. Irrigation plan.-Diversion from Hams Fork in section 31, township 21 north, range 114 west; thence along right bank of river 10 miles to siphon crossing the river where it reaches the project. Reservoir.-On the river above Kemmerer. Capacity, 100,000 acre-feet. The site is occupied now by a branch railroad. Construction of this reservoir may interfere with coal mining in the vicinity. Average estimated water supply.-Measured just below reservoir: Acre-feet. September-April (inclusive).............................................. 35, 00tf May..................................................................... 65,000 June................................................................... 33, 000 July.................................................................... 6, 000 August..............................................................___ 1, 000 Total............................................................. 140,000 * 22,000 acres used because of lack of water supply.
