Colorado Flooding Roads

The news received a loud ovation at the Gold Hill Inn Sunday night, where a crowd was gathered for a benefit for a Boulder County hospice facility. The program featured songs by Neil Young and was performed by Boulder area musicians including Cort McCumber and Molly O’Brian.
The road through Gold Hill has, until Sunday afternoon, the only open road between the mountain communities west of town and the flatlands. Traffic has been ferocious in the town, both ways, all hours of the day and night. and lengthy.

A Flood Warning remains in effect until 8:30 pm MDT Thursday for Northwestern Arapahoe, Western Weld, northern Jefferson. Larimer, Western Adams, Broomfield, Denver and Boulder counties. Widespread flooding is occurring.

Heavy rain fell last night and this morning from the Wyoming border south through Fort Collins, Loveland, Longmont, Boulder, parts of the Denver area and in the foothills. Moderate to heavy rain will continue through the day today and into this evening. Rainfall amounts from last night and this morning range from 2 to 9 inches. Nearly all ditches, canals, streams, low Lyings areas are full of water and a good number of them are flooding.

Stay Home. Many roads are flooded or washed out. Avoid flooded areas and do not drive through flooded roads. If rising water threatens. Move to higher ground.

Significant flooding is occurring along the Big Thompson and Saint Vrain Rivers.

Some locations that will experience flooding include: Denver, Fort Collins, Western Greeley, Northwestern Aurora. Lakewood, Thornton, Arvada, Westminster, northern centennial. Boulder, Longmont, Loveland, Broomfield, Commerce City. Northeastern Littleton, Northglenn, Brighton, Englewood, Wheat Ridge, Lafayette, golden, Windsor, Louisville, Erie, Greenwood Village, Superior, Federal Heights, Firestone, Western Denver International Airport and Johnstown.

Recommended actions

Most flood deaths occur in automobiles. Never drive your vehicle into areas where the water covers the roadway. Flood waters are usually deeper than they appear. Just one foot of flowing water is powerful enough to sweep vehicles off the road. When encountering flooded roads make the smart choice, turn around, dont drown.

Do not drive your vehicle into areas where the water covers the roadway. The water depth may be too great to allow your car to cross safely. Move to higher ground.

Excerpted from


  • Build an emergency kit and make a family communications plan.
  • Elevate the furnace, water heater and electric panel in your home if you live in an area that has a high flood risk.
  • Consider installing “check valves” to prevent flood water from backing up into the drains of your home.
  • If feasible, construct barriers to stop floodwater from entering the building and seal walls in basements with waterproofing compounds.
  • More about:
  • What to do before a flood.


  • Be aware that flash flooding can occur. If there is any possibility of a flash flood, move immediately to higher ground. Do not wait for instructions to move.
  • If you must prepare to evacuate, you should do the following:
    • Turn off utilities at the main switches or valves if instructed to do so. Disconnect electrical appliances. Do not touch electrical equipment if you are wet or standing in water.
    • Secure your home. If you have time, bring in outdoor furniture. Move essential items to an upper floor.
  • Be aware of stream, drainage channels, canyons and other areas known to flood suddenly. Flash floods can occur in these areas with or without typical warnings such as rain clouds or heavy rain.
  • If you have to leave your home, remember these evacuation tips:
    • Do not walk through moving water. Six inches of moving water can make you fall. If you have to walk in water, walk where the water is not moving. Use a stick to check the firmness of the ground in front of you.
    • Do not drive into flooded areas. If floodwaters rise around your car, abandon the car and move to higher ground if you can do so safely. You and the vehicle can be swept away quickly.
    • Do not camp or park your vehicle along streams, rivers or creeks, particularly during threatening conditions.

Buff Classic “epic” bike ride aiming higher


Hundreds of benefactors to bicycle farther,
higher for CU-Boulder scholarships Sept. 8

If the distance and difficulty of Colorado’s many organized bicycling events is any indication, a flat, 100-mile bicycle ride is not, for many riders, quite tough enough.

That’s one reason the 11th annual Buffalo Bicycle Classic’s longest route will go farther and climb higher than any of the event’s courses so far. The “Buff Epic” will span 110 miles and ascend a total of 6,250 feet. It retraces much of the most mountainous section of Stage 6 of the 2012 USA Pro Cycling Challenge.

The Elevations Credit Union Buffalo Bicycle Classic is scheduled for Sept. 8 and is expected to draw more than 2,000 participants. The event raises scholarship funds for high-performing University of Colorado Boulder students who qualify for financial aid.


The epic century ride will start on campus, ascend Boulder Canyon to Nederland, follow the Peak to Peak Highway past Ward, descend St. Vrain Canyon to Lyons, head north to Carter Lake and turn south to return to Boulder.

During the Buff Epic, Boulder Canyon’s westbound lane will be closed to traffic from 7 a.m. to approximately 9:30 a.m. Male and female riders in five age groups will compete for polka-dotted jerseys, signifying their climbing prowess. They will be judged by their times on the ascent of a 13.5-mile section from the base of Boulder Canyon to Barker Reservoir.

Times will be measured by individual riders’ GPS devices and recorded on While there is the canyon competition, ride organizers emphasize that the Buffalo Bicycle Classic is not a race but a ride for those of all strength and ability levels.

The 2013 Buffalo Bicycle Classic includes its traditional courses that cater to all cycling abilities: These courses include the 70-mile, 50-mile, 35-mile and 14-mile Little Buff family-friendly community ride.

“The Buffalo Bicycle Classic accommodates riders of every ability,” said Todd Gleeson, former dean of the CU-Boulder College of Arts and Sciences and one of the ride’s founders. Gleeson, a professor of integrative physiology, directs CU-Boulder’s new Health Professions Residential Academic Program.

“The Buffalo Bicycle Classic combines two things close to our hearts: access to higher education and the love of bicycling,” Gleeson said. “An event that combines both improves town-gown relations, heightens riders’ physical fitness and, most importantly, lowers one barrier to higher education.”

Since 2003, the Buffalo Bicycle Classic has raised more than $1.8 million for scholarships and funded about 800 scholarships.

Chris Kerns, who graduated cum laude in anthropology from CU-Boulder in 2005, is one of those scholarship recipients. He is now finishing a Ph.D. in archaeology at the University of Southampton, England, and figures he’s one of a relative few scholarship recipients who have completed a Buff Bike Classic century ride.

“Any opportunity to support deserving students in their academic endeavors is absolutely worth it. Great young minds can achieve amazing things as long as they get the support necessary to further their goals,” Kerns said. “The scholarship from the Buffalo Bicycle Classic is one way in which to support and inspire students to succeed and accomplish amazing things.”

Scholarship recipients are selected based on grade-point average and financial need. They cannot apply for the scholarship and don’t know they are being considered until they learn they have won. All net proceeds go toward scholarships, and a portion of the registration fee is tax-deductible.

7/14 3 p.m. Gold Hill residents advised to use Sunshine Canyon Drive
Fourmile Canyon Drive and Gold Hill Run are closed from Poorman to Dixon in Fourmile Canyon. Residents of Gold Hill are advised to take alternate routes. Sunshine Canyon Drive is clear.

7/14 2:56 p.m. Impacts to Ann U. White Trail/Wagon Wheel Gap Road
Water is currently running down Ann U. White Trail and rising quickly. Wagon Wheel Gap Road (off Lee Hill Road) may be affected because of trail drainage.

7/14 2:21 Call center now open
A public information call center is now open. Call 303-413-7730 for updates on today/tonight’s weather event and related emergency information.

7/14 2:12 p.m. – Rock slide on Boulder Canyon Highway 119
A rock slide has occurred on Highway 119 at approximately mile marker 35. The westbound lane is completely closed. The Boulder County Sheriffs Office and the Colorado Department of Transportation are en route to respond. Motorists can expect delays; alternate routes are advised.

7/14 1:10 p.m. – FLASH FLOOD WARNING for Fourmile Fire burn area
The National Weather Service has issued a FLASH FLOOD WARNING for the Fourmile Fire burn area effect immediately.

Prepare for possible flooding and take appropriate actions in low lying and heavy drainage areas for Fourmile Creek and Fourmile Canyon Creek.

The Boulder Emergency Operations Center is activated and providing support to field emergency operations.

Further information will be provided as it becomes available.

7/14 10:30 a.m. – Anne U. White Trail in north Boulder area is closed due to flooding
The Anne U. White Trail (which follows follows the Four Mile Canyon Creek in an area near north Boulder) was closed last night by the Sheriff’s office due to flooding. The trailhead is located off Wagonwheel Gap Road and Lee Hill Road.

Continued flash flood warnings in the trailhead area are expected throughout the day today. Damage to the trail, including wash-outs and log jams may require the trail to remain closed for longer for repairs.

Updates will be made available as repair assessments and time frames can be estimated by the Boulder County open space trails staff.

7/14 9:10 a.m. – Current status of Fourmile Fire burn area after last night’s storm activity
Boulder County Road Maintenance crews are in the area clearing roads and culverts. All roads are open with the exception of Fourmile Canyon from Poorman Road to Gold Run Road and Gold Run Road to Dixon Road. Even though the other roads are passable, people are being asked to proceed with caution because of the debris remaining on the roads.

This morning, deputies and firefighters are in the Fourmile burn area assisting residents and assessing damages. There have been reports of a number of structures (both residences and outbuildings) and vehicles that were damaged by the rising water and debris flows. The reports indicate that these occurrences were throughout the burn area and not in any one isolated location. At this time, we do not have any estimates of the total cost of damages from these storms.

The weather forecast for today is predicted to be similar to the weather patterns we experienced yesterday (July 13, 2011). Residents living in the Fourmile burn area need to remain alert and cognizant of the potential for additional flooding.

7/14 9 a.m. – Notice about water quality after heavy rainfall
Heavy rainfall increases the flow of sediment into our local streams and creeks, increasing the cloudiness of water. As a result of recent heavy rainfall over the Four Mile burn area, this sediment has been significant, contributing to a temporary discoloration of Fourmile Creek and Boulder Creek.

The cloudiness and discoloration is an indicator of poor water quality and can mean an increased level of pathogens, such as E. coli and Giardia. People should always avoid drinking untreated and unfiltered water from streams, creeks, lakes, etc. Cloudy, fast-moving water may also have hidden debris that poses a safety risk, so people should avoid recreational activity in the creeks after heavy rainfalls or, at a minimum, exercise extreme caution.

Treatment plants for drinking water are designed to remove sediment and disinfect the water against pathogens, so the cloudy stream is not a concern for tap water. The City of Boulder does not draw any of its drinking water from these creeks.

7/14 1:10 a.m. – Secondary surge has occurred, no problems reported in city
The secondary surge on Boulder Creek has moved through the City of Boulder without causing any major impacts. While some emergency staff will remain at EOC throughout the night to monitor the possibility of more bad weather, no additional updates to this website are anticipated until after 8 a.m. unless there is a significant change in circumstances.

7/14 12:45 a.m. – Second surge possible in City of Boulder between 1:15 and 1:30 a.m. – no significant impacts anticipated
Emergency officials are expecting a possible second surge of water from the Fourmile Canyon burn area in approximately 30 to 45 minutes from now. This surge could affect Boulder Creek and move into a portion of the city east of Eben G. Fine Park, similar to what occurred several hours ago. The surge is expected to be no worse than the first one, when the excess water fanned out and dissipated without causing any major problems in the city. As a result, no alerts are being sent out and no sirens are being sounded. Police officers are, however, walking the creek paths and urging anyone who might be outdoors in these low-lying areas to move away from the water. Emergency crews continue to monitor the anticipated impacts in the city, and if notifications become necessary, will notify dispatch immediately.

Flash flood warning in Fourmile Canyon:#boulderflood VIDEO OEM Updates


We just returned from Four Mile Canyon where the mudslides occurred. There were four of them which began at mile marker 8 just past where you turn to go to Wall Street. Four Mile Creek is black with soot. (see video)

It was continuing to rain. The slides get larger as you continue past mile marker 8. Even in our 4 wheel drive TV production SUV we could only make it to the second slide. The command center gave us an escort from Four Mile Fire department. We had to have a radio person with us in case it slid again and we got caught up in a slide.
Initially, a Boulder County Sheriff deputy came up on the slides during the down pour at around 6:00pm. He told us it was all he could do to drive out in his Sheriffs big SUV Chevy.
Four Mile fire chief said that a large amount of the slide had hung up about 50 feet up the hill on a rock out cropping. There was some concern that it would slide again on into the night as the rains continued.
Four Mile Fire was on the scene and stationed through out the canyon to watch for more slides. A large road grader was pushing dirt and a front end loader and 10 Wheel dump truck were working the larger slides.
The hope is to get the road opened by morning. The concern is that it will keep raining and cause major slides.

Boulder Creek levels to rise in the next few days


During the next several days, water levels in Boulder Creek will begin rising noticeably, which could potentially impact underpasses near the creek and the safety of creek activities. With higher temperatures and increased snowpack runoff anticipated, Barker Reservoir is expected to fill and spill as early as Wednesday, June 8.

The current flow in Boulder Creek, at Broadway, is about 200 cubic feet per second (cfs). Following CDOT work to remove debris from Boulder Creek in Boulder Canyon, the city will begin to release water from Barker Reservoir this afternoon in anticipation of the spill. This gradual increase of the creek flows will help to prevent a sudden increase when the reservoir fills. By the end of the day on Tuesday, the flow in Boulder Creek, at Broadway, could reach 500 cfs. Following the reservoir spill, Boulder Creek could reach 600 to 800 cfs, at Broadway. Additional precipitation may further increase the flows.

Anyone recreating in or near Boulder Creek should use caution. City of Boulder and Boulder County safety officials are evaluating the situation to determine when a tubing ban might be warranted.
