Greg Hobbs at the 2015 Martz Summer Conference (of course there is a projected image of a map — this one was the division of Colorado into water divisions heeding the advice of John Wesley Powell to organize by watershed)

In Colorado we have prior appropriation, the anti-speculation doctrine, and a long-lived and active water market, that have managed to keep the wolf at bay. Maximizing shareholder value is the wrong goal for the public’s water. Most water in Colorado is provided by local government entities.
Municipal use is a small part of the overall pie but large amounts of water are necessary for agriculture and the environment. You don’t want to squeeze either one too much. We’re not that good at forecasting the consequences of our engineering.
I asked Brad Udall if he thought the Colorado River Basin was in collapse. He said no, even in the worst case we should have 80% yield from the system. He said we have to use the water more wisely.
That is the definition of collapse: There is not enough water to stay status quo in the basin. This is at the same time that the environment requires that we undo some of our damage and share some water.

From the Sky-Hi Daily News (Lance Maggart):
The PHS has reduced the optimum recommended amount of fluoride in municipal water systems to a maximum of 0.7 milligrams per liter. The previous recommended range, from 0.7 to 1.2 milligrams, was changed this year for the first time since 1962.
Fluoride levels in Granby’s water supply vary depending on whether the water comes from the North Service Area or the South Service Area, two separate water systems providing public water service to community residents. Historically the fluoride levels in the two different service areas have been 1.1 milligrams per liter.
Following the new recommendations the North Service Area began reducing the amount of fluoride added to the water system. Granby Town Manager Wally Baird explained the levels in the North Service Area are already down to 0.9 milligrams per liter, and the Town plans to continue to reduce North Service Area down to the recommended level of 0.7 milligrams.
The South Service Area’s fluoride levels will remain at 1.1 milligrams per liter. No fluoride is added to the water in the South Service Area, explained Superintendent of the South Service Area Doug Bellatty. Instead the water levels in the South Service Area are naturally occurring.
Bellatty explained why the fluoride levels in the South Service Area will remain the same.
“The only process available to communities to lower the naturally occurring levels is through reverse osmosis,” he said, “which is extremely expensive and energy consuming.”
Bellatty pointed out that while the recommendation levels have been dropped, the Maximum Contaminant Level (MCL) — the highest level of a contaminant allowed in drinking water — for fluoride is 4 milligrams per liter.
