Abstract: An eight-year field program was undertaken from 1991-92 to 1998-99 to: (a) measure the loads in the ice sheet near the dam; (b) measure the load distribution between a gate and pier, and: (c) compare the loads on wooden and steel stoplogs. The most significant finding has been to show the importance of water level changes on ice loads. Ice loads are much higher and more variable (compared to purely thermal loads) when significant, but not excessive, water level changes occur. Ice load predictors have been developed, and they predict thermal loads well. They are less accurate for loads produced by a combination of water level and ice temperature changes.
