Forest Service wants to reconnect an aquatic ecosystem that was sliced apart by dredges in the mining era
Restoration plans are afoot for a degraded section of the Swan River, in Summit County, Colorado.
By Bob Berwyn
FRISCO — For all the gold Summit County’s old-timers managed to pull from local mountains and rivers, they left behind quite a mess. Along with toxic pollution oozing into rivers from some abandoned mines, other streams were turned completely inside-out, buried under tons of gravel.
That includes the Swan River, near Breckenridge, where the U.S. Forest Service now hopes to reverse some of the damage with an ambitious five- to 10-year restoration project.
The Forest Service aims to recreate of two miles of stream, riparian, and restore uplands that were all destroyed by the dredge boats. The agency also wants to decommission some roads in the area, build a new road and trail, all within a mix ownership of private, county, town, and national forest lands. Another element of the project would create fish barriers to protect populations of cutthroat trout. Continue reading

Environment: Probe of Arctic scientist ends inconclusively
SUMMIT COUNTY —A Kafka-esque federal probe of a polar biologist ended inconclusively this week, as biologist Charles Monnett got a mild slap on the wrist for an alleged breach of policy that was unrelated to the focus of the 2.5-year investigation.

What next for Colorado’s state fish?

SUMMIT COUNTY — After some genetic sleuthing and intensive scrutiny of historic fish-stocking records, a team of federal, state and university biologists said they’ve pinned down Colorado’s greenback cutthroat trout to just a single population — about 750 fish, all living in a four-mile reach of Bear Creek, a small Arkansas River tributary in the mountains west of Colorado Springs.
Greenback cutthroats — the Colorado state fish — were originally native to the South Platte drainage, but now appear to survive only in that single population outside of the species’ native range.
Biologists say native cutthroats in Colorado declined because of pollution, overfishing and stocking of native and non-native species of trout. Continue reading

By Summit Voice
SUMMIT COUNTY — Early spring weather might not be the best thing for skiers looking to extend the season, but it could be good news for Colorado anglers looking to get early access to high country lakes and streams.
And with the 2o12-2012 license year just a few weeks away, it could be a good time to make sure you’re ready by buying or renewing your license. The latest fishing brochure, with regulations and other info, is also available where licenses are sold and online at http://www.flipseekpubs.com/publication/?i=99616.

Habitat expected to shrink by 50 percent in coming decades
Anglers may have to climb high to find fish as global warming takes a toll on trout.
By Bob Berwyn
SUMMIT COUNTY — A combination of rising temperatures and changes in the timing of runoff and streamflows could reduce trout habitat in the western U.S. by about 50 percent during the next 70 years, with some populations disappearing completely within just a few decades.
The mechanisms for temperature-driven extirpations are complex, but the bottom line is that an ever-warming world isn’t going to leave much room for cold-blooded fish.
“They operate within a very narrow temperature range,” said U.S. Geological Survey biologist Andrew Todd. Variations in temperature can affect spawning, even if the temperatures don’t reach levels that are directly lethal to the fish, Todd said.
And the hydrology is also important, he explained. Even small changes in the amount and timing of precipitation can have a big impact on smaller headwaters streams. And unlike birds or mammals, trout don’t have the ability to move freely if conditions become unsuitable.
“They can’t just go to Montana,” Todd said. Continue reading

It’s not always about what you catch …
Boy and dog, keeping cool on a summer day at Trent Park, one of several stocked ponds at neighborhood parks in Summit County, Colorado.
SUMMIT COUNTY — Wow! The many fishing pics in the archives made me realize how much quality time I spent with my son last summer alongside local ponds, reservoirs and streams. Often, Kellen came along, which worked out really well, giving me a chance to work wirelessly, as in the photo above, while the boys caught supper — or not. Enjoy the photoblog from some of our favorite Colorado fishing holes and take your kids outside and fishing this summer. It’s one of the few things I’ve found that can compete with the attractive nuisance of video games. Continue reading
