Runyon Lake has reopened after a fuel spill in downtown Pueblo Monday shut the area down for three days.
Around 1:30 a.m. Monday a tanker truck from Alamosa-based Alta Trucking was filling an underground tank at 7th and Grand when the tank overflowed.
Officials estimate around 85 to 90 gallons of diesel fuel spilled and flowed into the storm sewer system. Crews worked to contain as much fuel as they could.
Later Monday morning, callers began reporting a gas odor near the Professional Bull Riders building. Crews determined that fuel had moved downstream through the storm sewage system underneath the Riverwalk, and are still working to absorb the fuel as it exits the storm water system near Grand and Santa Fe, into the Riverwalk.
The Riverwalk feeds into Runyon Lake, which then streams back into the Arkansas River.
Fire officials worked most of the day to contain the fuel spill at the Riverwalk near Grand and Santa Fe.
Crews set up four absorbent booms between there and the lake to try and collect as much of the fuel as they could before it seeped in to the Arkansas River.
The Colorado Division of Parks and Wildlife says that the fish in lake were unharmed in the spill thanks to the fuel floating to the top of the water.
Alta Trucking is expected to be billed by the city of Pueblo for the spill. The company says it will respond to the allegations Friday.
