Side-Channel Spillway North Hartland Dam, Ottauquechee River, Vermont: Hydraulic Model Investigation
The hydraulic performance of the side-channel spillway for North Hartland Dam was studied by means of a 1:50-scale comprehensive model that reproduced protions of the forebay area and earth dam, spillway approach, uncontrolled spillway, and chute-type exit channel. An estimated peak discharge of 30 400 cfs occurred at the project site in 1927 and is the maximum historical flood. The project design flood has a peak outflow cischarge of 171 000 cfs. The outlet works will be capable of passing 10 100 cfs at maximum pool with one gate inoperative, thereby reducing the required instantaneous spillway discharge to 160 900 cfs.
