Wet, cool spring brings relief to Midwest

The most severe areas of drought encompass parts of the central-southern plains, spreading southwest into parts of Colorado and New Mexico.

FRISCO — Drought woes have eased in the Midwest after a wet spring, but the far West,  California in particular, are facing continued dry conditions. California has reported its driest year to-date on record, with only 27 percent of normal precipitation for January through April. That doesn’t bode well for the state’s water supplies, although at least reservoir storage is close to normal in California.

New Mexico and Nevada are in bad shape when it comes to reservoir storage and there’s little relief in sight at the end of the snow season. Forecasters with the National Oceanic and Atmospheric Administration said dry soil conditions in the southwest could contribute to higher than average temperatures this summer. Read more »

FRISCO — With the Roberts Tunnel turned off and Summit County’s streams starting to surge with runoff, the water level in Dillon Reservoir has already come up about two feet since May 1, according to Denver Water’s Bob Peters, who recently issued the latest update for Denver Water’s storage and diversion system.

The Roberts Tunnel is used to shunt water from the Upper Blue Basin beneath the Continental Divide and into the South Platte Basin, where it can be stored in other reservoirs until its needed for municipal use in Denver Water’s service area.

With average precipitation the next few weeks, Denver Water anticipates that Dillon Reservoir will peak at an elevation of about 9,010 feet sometime in July. That’s about seven feet below a complete fill, equal to about 235,000 acre feet. If wet weather continues through May, the reservoir could fill completely in July, rising to 9,017 feet, equal to about 257,000 acre feet. Read more »

Colorado: River otters, bald eagles move into Summit County

Rare species find a home in the heart of a mountain resort community

By Bob Berwyn

FRISCO — Along with the well-documented saga of threatened Canada lynx making a comeback in Summit County, the local mountains are also home to several other rare species that are making comebacks.

It’s a sure sign that Summit County is a key biodiversity crossroads— something worth remembering on Endangered Species Day.

Just a couple of weeks ago, Colorado Parks and Wildlife district manager Sean Shepherd confirmed the first sighting of river otters in the Upper Blue Basin. Unfortunately, the pair of otters was found dead along Dillon Dam Road, most likely hit by cars.

But the fact that they are showing up in new places is nonetheless an encouraging sign, Shepherd said, adding that another otter was also killed recently along Highway 9 north of Silverthorne, near the Blue River campground.

Bald eagles, which can be spotted frequently along the Lower Blue River, have recently been reported around Dillon Reservoir, where a pair is setting up a nest on a platform built for ospreys. A pair of nesting ospreys, meanwhile, has built a nest atop a dead lodgepole pine in the vicinity of Heaton Bay campground. Wildlife biologists say bald eagles will sometimes kick osprey out their nest and take it over. Read more »

Morning Photo: Celebrating Dillon Reservoir

Water level to rise quickly the next few weeks

Monsoon lightning over a dwindling Dillon Reservoir in July 2012.

FRISCO — After months of so-so snowfall, Mother Nature opened the taps in April and early May, delivering well above-average precipitation. Denver Water’s latest projections suggest that Dillon Reservoir may come close to filling this summer, a huge turnaround from earlier predictions. This body of water in the heart of Summit County is gorgeous even when levels are low. In fact, I enjoyed cruising around the shoreline last summer and fall and finding new spots that aren’t accessible when the reservoir is at an average level, but it’s still nice to know that boaters will be able to enjoy nearly the full expanse of Dillon Reservoir this summer.

This November 2012 moonrise scene was photographed from a spot that would normally be under a few feet of water.

Energy: BLM eyes new rules for fracking on public lands

Posted on May 16, 2013 by Bob Berwyn

BLM wants to update 30-year-old fracking regs.

Common sense steps address some environmental and health concerns

By Summit Voice

FRISCO — An updated set of draft rules for fracking on public and Indian lands includes several common-sense safeguards that will help protect the human health and safety, as well as the environment. For starters, the rule requires disclosure of the chemicals used for fracking, a key measure that ensures transparency and gives the public some assurance.

The proposed rule beefs up standards meant to insure well bore-integrity, which will help verify that fluids used during fracturing operations are not contaminating groundwater. Operators must also have a plan in place for handling fluids that flow back to the surface.

About 90 percent of wells drilled on Federal and Indian lands use hydraulic fracturing, but the Bureau of Land Management’s current regulations governing hydraulic fracturing operations on public lands are more than 30 years old and were not written to address modern hydraulic fracturing activities.

Grand Canyon uranium mining ban withstands another test

Federal judge once again rejects mining industry challenge to withdrawal

SUMMIT COUNTY — A moratorium on uranium mining in the greater Grand Canyon region withstood another test this week, as U.S. District Judge David Campbell denied a uranium industry motion to reconsider his previous ruling to let the temporary ban stand.

Mining interests could still go to a federal appeals court, but for now, the withdrawal enacted last year by Interior Secretary Ken Salazar will stand.

“It’s another good day for the Grand Canyon, and for rivers, wildlife, and communities across the West,” said Ted Zukoski of Earthjustice, one the attorneys representing conservation groups and the Havasupai Tribe in the case.  “The court has now twice rejected the uranium industry’s attempt to cripple the Interior Department’s ability to temporarily protect lands from destructive mining.” Read more »

EU ice2sea report offers new estimates of sea level rise

Posted on May 16, 2013 by Bob Berwyn

The EU’s ice2sea program helps to determine potential future impacts of rising sea levels.

Research focuses on contribution of melting glaciers, ice caps and ice shelves

By Summit Voice

FRISCO — After four years of studies and more than 150 peer-reviewed papers, The EU-funded ice2sea program has concluded that melting ice may not contribute as much to sea level rise as some other studies have suggested.

Under a moderate greenhouse gas emissions scenario, the contribution from continental ice will likely amount to between 3.5 and 36.8 centimeters (1.4 to 14.5 inches) by 2100, the program’s leaders said this week, unveiling a new report that summarizes their research. The report is online at the ice2sea home page.

Some of the ice2sea studies have:

The new report includes several case studies outlining the impacts of sea level rise to specific areas, including economically valuable developed areas like the port of Rotterdam and the Thames Estuary, as well as natural areas with unique natural values, like the Machair ecosystems in Ireland and Scotland that thrive in a delicate balance of land and sea.
