Show III Colorado River Raver Runoff Seen been at 90 of Average The April through July runoff from the Colorado watershed above Lake Powell is expected to reach 75 million feet acre or 00 per cent of the longtime longtime long time average runoff the Bureau of announced last week Deficient March precipitation in the southern part of the Upper Colorado Hasin Basin has been balanced by in increased In In- creased snow accumulation in the northern northern north ern part of the basin THE PREDICTED forecast is based on 01 the seasonal accumulation of precipitation precipitation tation lation to April 1 at 58 stations and on April snow data darn at 48 snow courses within with in the watershed area It presumes normal nor mal mat precipitation during late spring and early summer Lake Powell behind Glen Canyon Dam Damis is expected to reach about elevation feet above mean sea level by midsummer 14 feet higher than last summer and 14 feet above its present level It will then contain million feet acre which is 55 per cent of its capacity The lake should remain near this level during the remainder of the recreation season and be lowered about eight feet during the winter ABOUT feet acre of runoff should originate above Flaming Gorge Dam This is 55 per cent above nor nor- mal Of or this amount feet acre will be stored in Fontenelle Reservoir With this expected normal above inflow for the current runoff season and increased in creased power generation at other hydro plants the bureau presently pre plans to continue a program that has been in effect the last two months of increasing Edith Gale returned from the Hospital Monday 1 after receiving major surgery the storage In Flaming Gorge Reservoir Reser voir this year The Th immediate effect of this program will be to Increase the reservoir level from feet at present to about abut feet above sea level by the end of th the summer thereby improving the use of existing boat ramps and considerably expanding the reservoir area In future years on an average inflow and power requirement year basis effort will be made mad to maintain the reservoir above elevation feet during each recreation recreation recreation tion season BLUE MESA Reservoir is expected to receive about feet acre of inflow inflow in in- flow which is only 71 per cent of the time long average If this amount of water is realized the lake should reach elevation 1 feet above with ausable a ausable usable content of acre Morrow 1 Point Reservoir immediately downstream from Its big brother Blue Mesa shall remain near full at feet acre throughout the year ON THE S n Juan River Navajo Lake should receive the smallest runoff only 36 per cent of normal The foot acre inflow it will receive should bring the lake level to elevation feet above A near constant discharge discharge discharge dis dis- charge cubic feet per second from Navajo Dam will keep the lanear la lae e near this elevation throughout the tourist tourist tour tour- 1st recreation season Lake Mead on April 1 was at elevation ele etc 1148 feet above or about three feet lower than a year ago The reservoir is now 73 feet below the top of the raised spillway gates at Hoover Dam The lake will be held near this level or will be allowed to rise slowly during the summer The lake at present present present pre pre- pre pre- sent contains million feet acre of av available storage or 60 per cent of its ts capacity |
