Enhancing Flood Control Reliability at Waterbury Dam
During routine maintenance at Waterbury Dam, the U.S. Army Corps of Engineers (USACE) identified operational behaviors suggesting potential excess resistance in the gates’ trunnion pins. that raised concerns about the performance of the dam’s spillway gates. Given the critical role these gates play in flood control, ensuring reliability of the dam’s spillway gates was essential.…

Read MoreBig Creek Dams 5 and 6 Concrete Material Testing
Big Creek Dams 5 and 6 impound water along Big Creek near Big Creek, California and were constructed in 1921 and 1923, respectively. New increases to minimum instream flows (MIF) require increasing the diameter of existing MIF conduits through the dams. The dam owner contracted a consultant to design the larger MIF conduits and associated…
