Milltown Reservoir Diversion

Milltown hero


Location: Milltown, MT

Applications: Erosion Control

Product Used: ARMORMAX


Over 100 years of deposited mine tailings prompted the Montana Department of Environmental Quality and the EPA to embark on a major initiative to breach the Milltown Reservoir Dam and clean up contaminated sediments. But maintaining the flow of the Blackfoot and Clark Fork Rivers called for a potentially expensive diversion channel.


Incorporating the ARMORMAX® 75 in the upper cross section to protect against the highest design flows minimized expensive gabion mattresses for use only in the low flow channel section.


The result was over $1.1 million in savings, and a significant time and labor reduction.
