U.S. ARMY CORPS OF ENGINEERS MISSOURI RIVER DIVISION AUGUST 1977 ...... --.---.---.-----~--.. Syllabus This atudy investigated a wide range of water resource probl... and opportunities related to the Missouri River and the six main stem d.... along an area extending over 1.500 miles from Sioux City. Iowa to Three lorks. Montana. Subjects of the study were: the feasibility of installing additional hydro-power generating units both at the main stem dams and adjacent to the river; resolution of bank erosion. waterlogging. and residual flood problema; opportunities for recre­ ation. fish and wildlife enhancement; operating plans of the main stem system considering future water use; and potential for extend­ ing naVigation upstream from Sioux City. Iowa. Several elements were dropped during the course of the study. Water sllocation and marketing was an initial objective; however. b.,in states indicated such studies to be untimely. This report. therefore. does not make any recommendations dealing with priorities of water use. Surface inundation and waterlogging along a 10-.11e reach upatream from the mouth of the Niobrara River during periods of high release from lort Randall have been judicially determined to require lederal compensation of the landowners. A separate re­ port will deal with thia problem. In response to the waterlogging problem at Buford-Trenton. North Dakota. the Corps has developed a drainage plan to be accomplished under existing authority. Ex­ tension of navigation past the main stem dams or only aa far as Yankton. South Dakota. i8 clearly infeasible even under the moat favorable aasumptions. Potential hydro-power addition. at the Oabe and lort Randall damait •• and a pumped-storage facility at Garrison have been deferred for future evaluation. The .elected plan includes elements for bank stabilization and recreation accsss. additional hydro-power capacity. restoration of trophy fishing at Lakes Oahe and Francis C""e, and National Wild and Scenic Rive~ designation of the GAvins Point-Ponca State Psrk reach. Plan cnwponents were nelectrrl fr::l'1l a.n array of alternat1."veft as.essed in terms of national ~conomic development, environmental qualley, and Racial and reF-ionRt effects. ~qnk atabilization con­ sists of desi~n and con~t~u~eion of soft nr~tect1on works emplo,ing river management techniques designed to preserve the existing environ­ .... nt while at tbe s ..... ti_ preserving high bank lands.

For the three hydro-power additions, annual benefits total 568,893,000 and annual coats equal $45,622,000 resulting in a 1.5 benefit-coat ratio. The plan selected for restoration of a northern pike fishery at Lak~s O~he and Francis Case consists of construction of reArin~ pandA and an enhanced lakeshore forage baAe at 12 sites at a coat of $4,270,000. IID~rov~ments in fishing oppor­ tunity will yield $1,080,000 in snnual ben~fits; and with annual costa totaling $363,000, the ratio of benefits to costa i~ 3.0.
