The Central Utah Water Conservancy District received a $72,007.30 surprise this month when the contractor for the Trial Lake Dam project left settled accounts with the district.

Sheldon Talbot, district engineer, said it was the first time in his experience with the district that a contractor did not take the full amount specified in a construction contract agreement.The dam was built by Gilbert-Western Inc. and adds 16,600 acre feet to the district's storage capacity. It cost the district about $1.7 million. The district is in the process of testing the new structure. It is presently half full and district employees are at the site conducting 24-hour watch during the initial filling. After the test fill is completed, the dam will be lowered to a specified level for the remainder of the winter.
