From The Montrose Daily Press (Andrew Kiser):
The Montrose City Council voted unanimously, during its Dec. 18 meeting, to award a contract change order to RJH Consultants for $72,100 in the redesign of Cerro Reservoir.
The original amount of $270K had to be increased as “surprises in the reservoir’s design showed a lot of unforeseen layers,” said City Engineer Scott Murphy to the councilors on Dec. 18.
The dam at Montrose Reservoir on Cerro Summit needed major repairs earlier this year, which required the lake to be drained over the summer, as previously reported…
The city has been trying to figure out dam conditions there for some time and was more recently able to send divers down a 15-foot opening in the dam works for inspection, Murphy said.
This inspection confirmed it was time to replace the outlet works for the 1912 dam.
The outlet works consist of an 8-inch pipeline that runs through the dam’s foundation and below the western embankment; the pipe is about 50 feet below the crest of the dam and dates back to the original dam construction…
He added the city is currently working on its contract bid with Colorado Division of Water Resources.
“Something with this class goes through a pretty thorough review process with the state,” Murphy said, estimating the city should be awarded the contract in the next two months.
Shortly afterward ground will be broken in early February, he said. The construction will then start later that month and finished end of 2019.
The reservoir is tentatively planned to be filled in the spring of 2020.
