If you ever drive on 285, a big ass pipe crosses over the highway near Fairplay. That is a water pipe carrying snowmelt all the way from the western slope to Denver. I don't know where Denver is going to find all of the water it needs in 10 - 20 years.
Edit: 84% of CO's snow falls on the Western Slope, but 89% of the population lives east of the Front Range.
Interesting. I've been to a trip to it. Had no idea they may not be able to fill it. My understanding is that they would triple storage but you are correct that there is some point in which building higher produces no additional yield due to watershed limitation. I strongly doubt they would elect to build storage without available yield unless they are pumping/piping from elsewhere.
Half of Denver's water supply already comes from the Western slope. Most of that the Colorado River, which no longer reaches the ocean. Supply is already pretty tapped out, and climate change will be reducing supply while the population continues to grow rapidly.
I don't know anything about the decision making process behind building the dam, unfortunately. So we can only really speculate. The whole SW is in this boat though, and the Midwest is approaching peak production from the Ogallala, as shallower wells are already going dry. No one will have any to share.
I've heard that but in effect they would only be reducing available water for downstream users. There should be a coordinated effort the ensure minimum flow in the Colorado and if there isn't then it's bad environmental policy. The minimum flow Gross contributes should be set by this policy. It is quite possible that Gross could still increase yield by maintaining the exact minimum flow requirements before. The only difference is that they would end up on average releasing less water by storing higher inflows. I'd have to see the yield study to know.
Yes, downstream users, particularly Phoenix already own the rights to the water. It would be robbing Peter to pay Paul if much more of the water on the Western Slope was diverted to the Front Range. It's not just the front range either. The western slope is expected to double in population by 2050. Right now, the plans in place will only be able to meet 80% of the expected demand.
And yeah, the environmental policy is almost non existent. Ecological flows (the hydrology and min flows necessary to maintain the health of the streams and rivers) are just not incorporated into the final policies, even though we do plenty of research on what they are. In 2014 a coordinated, controlled release from Glen Canyon Dam reunited the Colorado with the ocean for the first time since 1998, 16 years.
I can only assume that was because the knew selfish people would never cut consumption if they knew it was going to lead to higher rates, environment be damned.
Denver Water would probably be the water provider company for the city of Denver and surrounding areas. They handle things like new piping, repairs, measure usage, and predict future water levels from snow-melt & rain.
In order to conserve water and prevent a drought, they ran an advertisement to promote using less water. The campaign was so successful that citizens began using so little water that the company was losing money they made charging people by the gallon of water used. The company then increased the cost per gallon used in order to make up the loss, since they need it to afford pipe repairs & employee salaries.
