"The river has been dried up for 150 years because it's been used for 150 years," he said.
Colorado is one of two states that has all its fresh water originate within its borders (the other is Hawaii). Like most Western states, it parcels out rights to water based on seniority of the claimant, not necessarily proximity to rivers or lakes.
Between the mouth of Cache la Poudre Canyon and its junction with the South Platte River, 60 miles east, lie 24 diversion structures, typically dam and canal combinations. This network sends the river water to its historical owners, mainly farmers on Colorado's eastern plains.
The new project would be supplying water to the river's other users -- a ring of fast-growing communities that hug the northern edge of Denver's sprawl. It would take about 40,000 acre-feet from the river annually. An acre-foot is the common measure of water, consisting of an acre of water a foot deep.
Gary Wockner, an environmental activist who is helping lead the fight against the project, peered last week into one of the diversion channels -- a ditch known as the New Cache Canal off a dirt road just west of Fort Collins. A steady, clear stream flowed down the channel, carrying a pair of ducks.
"There's more water in this canal than there is in the river," Wockner said.
A few minutes later, he pulled his van over at the edge of a chunk of open space the city had purchased along the willow-lined banks of the Poudre and strolled down a dirt trail to the riverbed.
He walked across three-quarters of the riverbed -- nothing more than smooth, dry stones -- to the thin line of water that made up the Poudre. It is here, he said, that he takes his two young daughters to go inner-tubing during the few months the river flows high enough to enjoy, May through July.
Wockner and other opponents of the project argue that there is plenty of water in reservoirs on the eastern plains to meet the region's growth needs. The water district's clients should buy that water rather than drain the Poudre more, they contend.
Warner, however, said that would be prohibitively expensive. He added that 60% of the water that would go into the new reservoir was already being taken from the river; the district will just divert it to its own storage area. And the water will only be pumped from the Poudre during the peak flow months.
He also noted that, even if the dam and reservoir were not built, the district still had the rights to the water, and fast-growing communities in northern Colorado needed it.
"Whether this project's built or not," Warner said, "that's not going to go away."
