Garrison dam, the first dam built under the Pick-Sloan Plan.
(1888 - 1987)
Billings, Montana based Bureau of Reclamation engineer who was
working on a master plan to control flooding on the Missouri River
when the three spring floods inundated the mid-west in 1943.
Sloan's plan, called for controlling the Missouri River flooding by
building 100 smaller reservoirs on tributaries. This would
allow for greater flexibility than large impoundments on the
mainstem of the river, and provide wide-spread distribution of
irrigation water over the 1 million square mile basin.
Sloan's plan was championed by Secretary of the Interior Harold
Ickes. In the end, this scheme became the second (and
unbuilt) junior half of the Pick-Sloan Plan. Click here for a profile of Glenn Sloan
