Heavy snowpacks, warm spring forecast prompt warnings

A skier walks by huge pile of snow at Loveland Basin on Monday. Heavy snowpacks have state officials concerned about possible spring flooding.
Supersized snowpacks and forecasts for a warm spring have large parts of the state on flood watch.
State snowpacks, at 126 percent of average, are their highest in a decade, with regions such as the Arkansas River Basin seeing the deepest snows in more than 40 years, the Natural Resources Conservation Service said.
Last week, the Garfield County Sheriff's Office warned residents to prepare for a possible surge in stream runoff. Snowpack in the Colorado River Basin, home to Garfield County, is 127 percent of average.
The state also started asking residents to prepare for what could be an active flood season, advising homeowners to check flood insurance and to buy coverage if none was in place.
"It appears we have a very challenging year ahead of us," said Harris Sherman, executive director of the Colorado Department of Natural Resources. His comments came at a meeting of the state's flood task force Monday morning.
Statewide, snowpacks in all mountain watersheds are above average, a rarity in Colorado.
Though snowpacks along the northern Front Range are just slightly above average, the Arkansas River Basin, whose waters serve Pueblo and Colorado Springs, are at 156 percent of average.
Southwestern parts of the state also are seeing critically high snowpacks. In the Rio Grande Basin, for example, the snowpack is at 151 percent of average and emergency officials are monitoring stream flows and ordering sandbags.
"At 150 percent of average, as a general rule of thumb, that's where we begin to get concerned," said Mike Gillespie, snow survey supervisor for the Natural Resources Conservation Service.
Flood danger is likely to be highest beginning in late April and continuing through June as mountain snows melt, officials said.
"It's impossible to predict precisely, but I think we're about 45 to 75 days away from peak runoff," said Kevin Houck, an engineer for the Colorado Water Conservation Board's flood protection unit.
Colorado's mountain snows, even in deep years, often melt in an orderly fashion.
But if high runoffs combine with intense spring rainstorms, flooding is likely, officials said.
Rafters and kayakers should be particularly careful this spring, said Robert Jarrett, a hydrologist for the U.S. Geological Survey.
"We don't know how the runoff is going to come off," he said. "But what we do know is that there are going to be many months of high flow and the waters are going to be freezing cold. Anyone who gets in who can't get out quickly is going to be in trouble. That's what the public needs to know."

No - what they didn't say is that we are still (and will always be) in a drought, no matter what. So no campfires for us again!

Wait a minute, freethought might be on to something. Maybe we should change our state motto (again) to reflect this. How about:
Colorado - where Texans come to die.
or
Colorado - too tough for the rest of the country

Shaupeen, LMAO!!!! Sorry, no campfires ever again in the state of Colorado. Too many idiots that don't know what they are doing and too many beetle killed trees standing around. On second thought, a good coat of fire might make some of the forests look pretty good again and spark some new natural growth... But the forest service firefighters will likely take care of that.

"so goes those second mountain homes..." only for those idiots that do not listen to their fire department. That is, clear the trees and brush from around your house, don't stack firewood next to your house, etc..

Well forwhatitis/ForwardXX, it really no longer matters. For all intents and purposes, the trees that will be infected are pretty much done. The time to have worried about this was about 4-6 years ago, not now. The smart thing is to allow some controlled burns run through the snow this spring. It will keep it under control. Then once an area is clear, go ahead and re-seed, or just allow nature to take place. Of course, if we do it, we would be smart to diversify.

BTW, anyone willing to tell us where we can find the information about who lives in a flood-prone area? I'm sure they'd like it better if we all buy flood insurance, but some of us don't like to waste money on ominous speculations about the future. Then again, others of us really do.

I suppose if we're going to have a warm spring we'll have to hear about global warming ad nauseum all summer. That is, if the weather people are correct---they've been pretty wrong all winter.
Also, how much water do we need for CO not to be in a drought????

Re:Top Spring and early summer floods. Did Denver and the metro area and I-25 corridor experience a SMALL flooding in June 1965?? Floodplain. When did we in the front range begin using and recognizing that term? Why was Chatfield Dam constructed? Yes,editors thanks for your oversight.

Many Americans are still unaware that flood damage is not covered by their homeowners insurance policy. Others are in denial about the serious flood risks to which they are exposed. Though definitive figures on the potential market for flood insurance are difficult to obtain, consider the following statistics:
• Floods are the nation's #1 natural disaster.
• 20 to 25 percent of all paid claims are from low to moderate risk areas, yet a large percentage of residents in these areas do not have flood insurance.
• In high-risk areas, conservative estimates show that only one-third to one-half of residents have flood insurance.
For a number of flood disasters in the past few years, only 10 to 20 percent of the victims in high-risk areas had flood insurance coverage. The remaining 80 to 90 percent had to rely on taxpayer-funded Federal disaster assistance, low-interest loans, tax write-offs, or savings to help them recover.
