| Summary: | THE GARRISON DIVERSION UNIT AN INTEGRAL PART OF THE MISSOURI RIVER BASIN PROJECT AUTHORIZED BY CONGRESS IN THE FLOOD CONTROL ACT OF 1944 NORTH DAKOTA'S STAKE IN THE MISSOURI RIVER DESCRIPTION OF PROJECT PLAN 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 1 850 by pumping water from the main reservoir into the Snake Creek Reservoir. From this reservoir water will flow by gravity through the 73 mile MeClusky 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 Rockford Canal will head eastward utilizing the improved James 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 mile Oakes Canal, which will convey it to Taayer Reservoir for regulation and release to irrigable areas. The 6,51 5 acre Lincoln Valley area will be served directly from the MeClusky 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.
