| Summary: | THE GARRISON ■ IIVERSION UNIT AN INTEGRAL PART OF THE MISSOURI RIVER BASIN PROJ THORIZED BY CONGRESS IN THE FLOOD CONTROL ACT OF 1944 NORTH DAKOTA'S STAKE-IN THE MISSOURI RIVER EXPLANATION Irrigable Land -Initial 250,000 Acre Project Irrigable Land - 1,000,000 Acre-Project Land Under Investigation Garrison Diversion Conservancy District Boundary Canal Initial Phase Ultimate Project DESCRIPTION OF PROJECT PLAN Dam And Reservotr — Proposed Dam And Reservoir — Existing Pumping Plant -Initial Phase Pumping Plant - Ultimate Project Fish And Wildlife Areas Recreation Areas Municipal Water Supply Water will be supplied for the Garrison Diversion Unit from the Garrison Reservoir. The Snake Creek Arm of Garrison Reservoir, which is separated from the main reservoir by the Snake Creek Embankment, will be maintained at elevation I 850 by pumping water from the main reservoir into the Snake Creek Reservoir. From this reservoir water will flow by gravity through the 73 mile McCIuaky Canal to the Lonetree Reservoir located at the headwaters of the Sheyenne River and approximately at the divide between the Missouri River and Hudson Bay drainage basins. A system of canals and existing rivers radiate from the Lonetree Reservoir to convey water to the service areas. The 93 mile Velva Canal will convey water northward to serve the 103,800 acre Middle Souris Area; the 60 mile New Rock ford Canal will head eastward utilizing the improved lames River channel for the first 30 miles and then will be diverted at the Hamburg Diversion Dam to the man-made portion of the canal to serve the 20,935 acre New Rockford Area. Its extension, the 5 5 mile Warwick Canal, will continue easterly to serve the 47,220 acre Warwick-McVille Area. The 20 mile James River Feeder Canal will convey water from the Hamburg Diversion Dam southeasterly to the James River and then southerly to the Jamestown Reservoir where it will be regulated for release to the 13,350 acre LaMoure Area and the 45,980 acre Oakes Area. Scattered irrigable tracts in the LaMoure area will be served by 1 4 separate pumping plants. Water for the Oakes area will be pumped from the James River into the 1 I mile Oakes Canal, which will convey it to Taayer Reservoir for regulation and release to irrigable areas. The 6,515 acre Lincoln Valley area will be served directly from the McClusky Canal and the 12,200 acre Karlsruhe Area from the Velva Canal. Municipal water users will obtain their water supplies from project canals through works that they construct and maintain. Irrigation distribution systems will branch out from principal supply canals to irrigable lands. Drains to remove surplus water from irrigation will be installed as required.
