Sometime in the middle of next year, if Northern Water gets its way, the bulldozers will start piling earth and rock 25 stories high to plug this dry basin southwest of Loveland forever. Four miles to the south, they’ll build another dam to keep their newly-made bathtub from leaking out the back toward Lyons. Drill crews will bore a massive pipeline through the hogback making up the east edge of the bathtub, in order to feed Carter Lake a few hundred yards to the east. They’ll move a power line. Help build a surrounding open space park. Upgrade a sewage plant in Fraser. Four years later, they’ll close dam gates reinforced to hold back 29 billion gallons of life-giving water.
