Colorado finalizes climate plan

Colorado recorded the greatest increase in average maximum temperatures — between .7 and .9 degrees — from the old normals, compiled between 1971 and 2000, and the new normals, which are based on temperature readings between 1981 and 2010. On average across the U.S., the new average temperatures are about .5 degrees warmer.

Multiple state agencies will eye adaptation, mitigation strategies

Staff Report

Colorado’s new climate plan calls for an all-hands-on-deck approach, with various state agencies working together, and with the public, to address the potential impacts of rising temperatures.

Acknowledging that average temperatures in the state could rise by as much as 2.5 to 5 degrees Celsius in the next few decades, Gov. John Hickenlooper called on Colorado make preparations now.

“Colorado is facing a potential increase in both the number and severity of extreme weather events,” Hickenlooper said in a prepared statement. “We’ve seen what Mother Nature can do, and additional risks present a considerable set of challenges for the state, our residents, and our way of life. This comprehensive plan puts forth our commitment from the state and sets the groundwork for the collaboration needed to make sure Colorado is prepared.”

Scientists tracking Chesapeake Bay algae blooms


Recent algae blooms in Chesapeake Bay are some of the most intense on record.

Studies eye potential human health risks

Staff Report

FRISCO — The West Coast isn’t the only place seeing unprecedented algae blooms this summer. Recent water sampling by researchers at William & Mary’s Virginia Institute of Marine Science show some of the densest concentrations of algae recorded in Chesapeake Bay in recent years.

According to the scientists, the current blooms are dominated by an algal species known to release toxins harmful to other marine life, particularly larval shellfish and finfish. Although the recent algae blooms haven’t been directly implicated, there have been some reports of small small numbers of dead fish, oysters, and crabs from the lower York River and adjacent Bay waters associated with nearby blooms.

Upcoming seminar spotlights regional water issues

CRWCD’s annual water seminar features leading national and regional water and climate experts

Several weekend stories addressed water quailty issues.

Got water?

Staff Report

FRISCO — Colorado this summer may have escaped the severe drought plaguing much of the West — at least for now — but that doesn’t mean the state is immune from regional water woes.

Planners and water users know very well that huge long-term challenges remain for all the states in the Colorado River Basin, and some of those issues will be highlighted during the Colorado River Water Conservation District’s Sept. 10 water seminar in Grand Junction.

Two of the most important women in Western water leadership will be addressing the Colorado River District’s popular Annual Water Seminar in Grand Junction, Colo., that takes place Thursday, Sept. 10, 2015, from 9 a.m. to 3:30 p.m. at the Two Rivers Convention Center. Continue reading

Wet spring and summer help avert worst of water shortages for now

Staff Report

FRISCO — Water storage in Lake Powell peaked on July 14 this year and has started its annual seasonal decline that will continue until spring runoff starts early in 2016, according to an Aug. 18 update from the U.S. Bureau of Reclamation.

Study quantifies environmental footprint of food waste

Cutting food waste would save huge amounts of water


Food waste has a huge environmental footprint.

Staff Report

FRISCO — Food waste doesn’t just mean that a few scraps end up being tossed in the garbage bin. There’s a huge environmental footprint, including the waste of water associated with the production of the food.

In the EU, according to a new study, the surface and groundwater footprint from avoidable food waste has reached an average of 27 liters per person, per day, which is slightly higher than the average amount per capita municipal water use. The rainwater footprint is even higher, at 294 litres per capita per day, equivalent to the amount used for crop production in Spain.

And the amount of nitrogen contained in avoidable food waste averaged 0.68 kg per capita per year. The food production nitrogen footprint was 2.74 kg per capita per year, the same amount used in mineral fertilizer in both the UK and Germany put together. Continue reading

Study warns of unsustainable global groundwater use

New research ranks world’s most threatened aquifers

Staff Report

FRISCO — Scientists this week said that many parts of the world are using groundwater at an unsustainable rate, without any clear idea about when the water might run out. The most overburdened aquifers are in the world’s driest areas, which draw heavily on underground water. Climate change and population growth are expected to intensify the problem.

After studying the world’s 37 largest aquifers, the research team said the Arabian Aquifer System, an important water source for more than 60 million people, is the most overstressed in the world. The Indus Basin aquifer of northwestern India and Pakistan is the second-most overstressed, and the Murzuk-Djado Basin in northern Africa is third. Continue reading

Summit County: Dillon Reservoir expected to fill within a week

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.

Staff Report

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
