Colorado Flood Evacuations: Town of Crook ordered out overnight, Sterling evacuations extended

DENVER - Keep checking this page for the latest evacuation or pre-evacuation information. The latest changes will be brought to the top of this page and organized by the reporting agency.

-- Town of Crook (as of 2:30 a.m. Tuesday) --

The Town of Crook was ordered to evacuate early Tuesday morning because of the possibility of flooding.

Crook is about halfway between Sterling and Julesburg, just north of Interstate 76.

"The Town of Crook and residents along the north side of CO138 along the area river basin are being evacuated due to historic high levels of water in the Harmony Ditch close to Crook," the Logan County Office of Emergency Management wrote in a post on Facebook

"If the ditch breeches its banks it will substantially flood the town," officials warn.

Crook Fire Department personnel went door to door with the evacuation message and a reverse target notification was also sent, according to officials.

The previous evacuation along the river basin south of CO 138 remains in effect.

Logan County officials said evacuation routes are still being determined. Due to road closures on CO 138 evacuees will have to use county roads north of CO 138.

"It appears the river is rising in the Crook area. River levels are being monitored by Crook Fire," officials said Tuesday morning.

The Town of Crook posted on Facebook, "Crook Firemen and local farmers are continuing to work through the night to try to keep Harmony Ditch from breaching north of the town of Crook. We all appreciate their hard work. Stay safe neighbors."

A shelter will be in place at Caliche School if necessary. If you have further questions, contact 970-886-2100.

City officials have issued re-evacuation orders to the Greens (Twin Peaks Cir and Columbia Dr) Champion Greens (Doral Dr and Champion Cir) and the Valley neighborhood (Hayden Ct, Wade Rd. and Troxell Ave).  The Royal Street Mobile Home Park evacuation is still in effect.  These re-evacuations are due to rain west of Lyons and in Longmont.   The city is closely monitoring rain gauge levels at five stations along the South St. Vrain and North St. Vrain rivers.     

We are seeing the St. Vrain river levels on the rise. 

There are several neighborhoods evacuated in Longmont. They include: The Longmont Estate Greens and Champion Greens neighborhood, near 9th Ave and Airport Road.

-- Sterling (as of 4:30 a.m. Monday) --

City officials believe the river has crested in Sterling and is continuing its movement through the river valley north. Although some water has surfaced along Highway 6 inside city limits, there is still some room under the girders of the river bridges on the highway.

Evacuation orders have been extended to include residents living along the Platte River Basin up to the Logan/Sedgwick County line at Logan County Road 97. This does not include the towns of Iliff, Proctor and Crook. This evacuation boundaries remain Highway 138 on the northwest and I-76 on the southeast side of the river.

Road closures at this time include Hwy. 6 from the Chestnut Overpass to I-76 and Logan County Road 55 from Iliff to I-76 and.

We're unsure what to expect as the water continues through Sterling and north through the river valley, but suggest that people living along the river bottom:

-- Move your important belongings off of the floor and onto shelves or counters, 
-- Consider putting important document in water-proof containers
-- Be prepared to evacuate without delay if a notice is given in your area
