Denver Water juggling inflow, outflow

Flows in Blue River tributaries like Straight Creek are near their seasonal peak.
*Story corrected at 2 p.m. Dillon Reservoir outflow to the Blue River increased to 1,600 cfs Monday, July 15.
FRISCO — Dillon Reservoir should be full within a week, according to the latest update from Denver Water, which just bumped up the outflow to the Lower Blue to make room for more runoff the next few days.
As of June 15, Denver Water was releasing about 1.600 cubic feet per second from Dillon Reservoir, with about 2,200 cfs flowing in from the Blue River and its tributaries. And Denver Water is expecting more high inflows for the foreseeable future, according to a recent email update:
“A fresh look at the estimated level of snowpack above Dillon Reservoir … tells us there is still eight inches of snow in some places, meaning high flows can be expected for the foreseeable future. The good news is that inflows to Dillon Reservoir – which have ranged from 2,206 to 2,623 over the past several days – appear to be trending downward.” Continue reading

Right-wingers frame drought as battle between environment and people; Colorado could avoid similar showdown with good planning
By Bob Berwyn
FRISCO — Apparently, the lack of water in California has hindered the ability of some of the state’s elected officials to think straight.
Completely ignoring the facts that California’s precipitation has been well below average for four years in a row, and that the state’s temperatures have running at or near record highs, some Republican congressmen are calling the Golden State’s current dry spell a “man-made drought.” Continue reading

Australia’s blistering Millennium Drought spurred wholesale changes in water use.
Regional water czar directed coordinated drought response
By Bob Berwyn
FRISCO — Drought-prone cities and regions around the world can look to Melbourne, Australia to get an idea of what it takes to tackle water shortages during extended dry spells — and to prepare for future droughts, which are projected to become more frequent in some regions as global warming intensifies.
As the worst drought in Australia’s history took hold during the late 1990s, the city’s 4.3 million residents were able to cut their daily water use by half, to just 41 gallons per per person, according to a new study. Continue reading

Good news for boaters

Blue River snowpack still growing.
FRISCO — Late-season storms have helped boost snowpack in the Blue River to near last year’s level, promising healthy runoff and flows in Summit County, according to Denver Water.
The effects of the steady barrage of spring storms is already showing up the Lower Blue River, where flows are increasing due to increased releases from Dillon Reservoir, according to Denver Water, which won’t be diverting water through the Roberts Tunnel until mid-July at the earliest.

New waterway could take a huge environmental toll
Preparations have started for construction of a new canal connecting the Atlantic and Pacific Ocean across Nicaragua. Map courtesy Pedro Alvarez Grou.
FRISCO — Expediting construction of a planned transoceanic canal in Nicaragua raises a host of environmental and social issues, according to a panel of scientists who recently met at a conference to discuss the potential impacts of the project.
The scientists urged caution and international collaboration, saying that sediment discharges during construction will threaten aquatic species, Nicaragua’s lucrative ecotourism and the supply of fresh water for drinking, irrigation and power generation.
The Nicaragua Interoceanic Grand Canal will cut through Lake Cocibolca , Central America’s main freshwater reservoir and the largest tropical freshwater lake of the Americas. The plan will force the relocation of indigenous populations and impact a fragile ecosystem, including species at risk of extinction, according to Rice University environmental engineer Pedro Alvarez and other members of the consortium.
