Too much of a good thing — The Pueblo Chieftain #RioGrande

Rio Grande and Pecos River basins

From The Pueblo Chieftain (Matt Hildner):

Too much water has become a bad thing in the Rio Grande basin. That might seem like nonsense in a region that has seen below-average stream flows for most of the last 12 years, but inaccurate stream forecasts coupled with the demands of the Rio Grande Compact have put water managers and users in a pinch. The compact governs how much water Colorado must send downstream and includes separate delivery schedules for the Rio Grande and Conejos River.

Those deliveries run on a sliding scale with the highest demands in wet years and the lowest ones in dry times. Each spring, the state engineer’s office relies on stream forecasts from the Natural Resources Conservation Service to balance how much runoff can be diverted by irrigators with how much must go to New Mexico.

The service draws that forecast partly from the eight automated snow gauges and a string of manual snow survey sights in the basin. But this year’s projections were low by roughly 50,000 acre-feet on the Conejos and almost 150,000 acre-feet on the Rio Grande, Division Engineer Craig Cotten said. That has left Cotten and his staff in the position of curtailing or limiting the amount of water that irrigators would otherwise be entitled to according to their respective water rights.

“The most senior water rights on both rivers are being curtailed dramatically in order to meet the compact,” Steve Vandiver, director of the Rio Grande Water Conservancy District told the basin’s roundtable earlier this month.

Moreover, the service’s snow measurement and forecasting program may have an uncertain future. Last year, the service proposed eliminating 47 of the 110 manual snow survey sites in Colorado to meet agency budget cuts. While those sites were saved, the threat of future funding cuts along with the inaccuracies plaguing the forecast have led officials in the Rio Grande basin to look at other options.

The Conejos Water Conservancy District is in the middle of a $237,000 project that will install a temporary radar system, six weather stations and a string of new stream flow gauges. The aim is to get a more accurate forecast that will reduce curtailments for water users. In 2012, the Conejos district estimated that those curtailments cost water users in the basin up to $13,000 per day.

“We can’t realistically blame Craig because it’s the forecasting error,” said Nathan Coombs, the district’s manager. “We don’t have anything else that helps us.”

The Conejos basin is home to two of the automated snow gauges run by the service.

The radar, which will be located either at Antonito or Alamosa, will give officials a clearer picture of where storms are happening, while the six weather stations will allow them to determine how much the storms are depositing.

Moreover, the project will add flow gauges to key tributaries of the Conejos such as Elk Creek and the South Fork of the Conejos.

“If we can start measuring better what these tributaries are doing, that will give us an indication of what these sub-basins are looking at,” Coombs said.

The snowpack and stream flow data gathered by the district will be turned over to researchers at the National Center for Atmospheric Research and the National Severe Storms Laboratory. In turn, those researchers will try to use that data to create a forecasting model. Coombs said the district will stack up that end product with the service forecasts.

“If there’s enough discrepancy to pursue it, that’s how we’ll go,” he said.

The Colorado Water Conservation Board played a role in funding the Conejos project and also has pursued the use of satellite technology to help increase the accuracy of snowpack measurement.

“We’ve had this conversation a lot,” Travis Smith who represents the Rio Grande on the board, told The Chieftain. “Forecasting drives our compact decisions.” Smith, who has been heavily involved in fire recovery issues in the Rio Grande’s headwaters, said temporary radar near Wolf Creek Pass that’s been installed to warn of late summer and fall monsoon storms, may end up playing a role for winter snowstorms as well.

But moving state officials toward improved forecasting can be difficult given that two of the biggest water management organizations in the state — Denver Water and the Northern Colorado Water Conservancy District — do their own forecasting independent of the service.

Still, Smith sees a potential ally in the Arkansas River basin, where water managers are dependent on service forecasting for its voluntary flow management program and reservoir operations.

Mike Gibson is chair of the Rio Grande Basin Roundtable, which also divvies up state funds for water projects and funded a portion of the Conejos pilot project. He wants all options left on the table.

“I personally feel we need to pursue all avenues available until we come up with a better system than we have now,” he said.

Environment: Bulkhead a big step in Peru Creek cleanup

FRISCO — For decades, the abandoned Pennsylvania Mine high has been oozing heavy metals — zinc, manganese, cadmium, lead and and arsenic — into the waters of Peru Creek, a small tributary of the Snake River near Keystone, Colorado. The site has been the focus of intensive study during the past 15 years with the goal of improving water quality downstream.

Last week, engineers and environmental experts took a big step toward trying to staunch that flow by blocking one of the mine tunnels. If all goes well, the new bulkhead could reduce the direct discharge from the mine by about two-thirds, said Jeff Graves, a remediation expert with the Colorado Division of Reclamation Mining…

Summit County: The Pennsylvania Mine gets plugged

From the Summit Daily News (Ben Trollinger):

On Friday, Oct. 17, Stiegelmeier was one of several federal, state and local officials marking a milestone for the centerpiece of the county’s current mining cleanup efforts — plugging the Pennsylvania Mine.

About 8 miles east of Keystone, the abandoned mine is Summit County’s biggest mess. The mine, considered the worst in the state, spews toxic heavy metal concentrates and acidifies water flowing into the Peru Creek, a tributary of the Snake River, which feeds Dillon Reservoir. Peru Creek is without fish, insects or other aquatic life. The Snake River has life, but it’s sparse and found only in the lower reaches. In 2007, a burp of acidic water from the abandoned mine killed fish all the way to Keystone, county officials said.

This past week, the Colorado Division of Reclamation, Mining and Safety finished installing one of two bulkheads, massive plugs of concrete and steel built about 500 feet inside the mine.

According to project manager Jeff Graves, once both bulkheads are installed, toxic burps and blowouts will be a thing of the past.

“That won’t happen again — it can’t,” he said.

The bulkheads prevent water from flowing through the mine. Water will back up inside, reducing the amount of oxygen the metals and sulfides are exposed to, which should improve water quality.


Though the more than $3 million project still has far to go, reclamation efforts seem to have had positive impacts already. Last year, the Peru Creek turned reddish-orange seven or eight times. That hasn’t happened once this year.

In addition to the bulkheads, new drainage ditches channel water away from waste-rock piles. Those piles have been capped. Eventually, they’ll be revegetated. Limestone has also been strategically added to raise the pH of the water, which could help filter out metals into settlement ponds.

Organizations involved in the project include: the Colorado Division of Reclamation, Mining and Safety, the U.S. Environmental Protection Agency, the Colorado Department of Public Health and Safety, the U.S. Geological Survey, the U.S. Forest Service, Summit County Open Space and Trails, Northwest Council of Governments, the Snake River Watershed Task Force, the Blue River Watershed Group and the Keystone Center.

Clean water drives Colorado tourism and business — Taylor Edrington

From The Pueblo Chieftain (Taylor Edrington):

There truly is no better feeling than stepping into a beautiful, high-mountain stream or river in Colorado on a quest to fool one of its inhabiting trout. It’s a surreal surrounding — with the crisp, clean air, the clean, cool water and the rugged landscapes that make up our playground as an angler in Colorado. I have been exploring Colorado’s backcountry fly fishing opportunities my entire life, and have made it my mission to help other outdoor enthusiasts experience Colorado’s phenomenal trout streams.

As a Colorado business owner, and as a sportsman, exploring Colorado’s Gold Medal trout streams and all they offer is priceless. However, these bodies of water are at an increased risk because of confusing decisions from the Supreme Court about the jurisdiction of the Clean Water Act.

Fortunately, there is a rule being proposed by the Environmental Protection Agency and Army Corps of Engineers that clears the muddied waters and ensures we have rules in place to protect the waters that supply drinking water to nearly three out of four Coloradans. These agencies are in the process of taking input from the public right now on how to improve the Clean Water Act.

I support the efforts to clarify the Clean Water Act because I’ve seen firsthand that healthy headwaters and streams — and our outdoor way of life — depend on clean water. For sportsmen, this proposed rule is critical. In addition to reducing flooding, filtering pollution, and recharging underground aquifers, clean, productive wetlands and headwater streams here in Colorado provide essential habitat for fish and wildlife.

Beyond inspiring aesthetics, outdoor recreation is also big business, contributing over $686 billion to our national economy annually. Here in Colorado, hunting and fishing alone is a $1.5 billion industry, contributing $150 million in state and local taxes each year and employing nearly 19,000 Coloradans. That means this rule also matters to our economy.

Recently I was guiding a group from Williams Lake, British Columbia, Canada, on my home water —the Upper Arkansas River in Bighorn Sheep Canyon. We enjoyed a typical day on Colorado’s longest Gold Medal River — plenty of fish to the net, beautiful surroundings, the sounds, the smells, the essential Colorado fly fishing experience. During the day we discussed the recent Mount Polley disaster near their hometown.

The Mount Polley Mine tailings pond dam breached in that crisis, releasing 17 million cubic meters of slurry into the local watersheds. This disaster destroyed all watershed habitats in the nearby area, drinking water sources and much more.

While we were discussing the tragedy, I realized that all too often we take clean water for granted. Properly managing our watersheds requires vigilance, and it starts with a restored Clean Water Act.

Yet, instead of working for clean water, some members of Congress are actively trying to scuttle the EPA’s and Army Corps’deliberative process. I urge our U.S. senators to stand up for the 10,000 miles of streams and 2,000 lakes we have in Colorado that are at risk.

I personally spend countless hours fly fishing throughout Colorado. My business depends on the great resources this state has to offer. Restoring the Clean Water Act is the right thing to do, to protect what we have.
