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 darn; (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 identify the importance of water level changes on the resulting ice loads. Ice loads are much higher and more variable compared to purely thermal loads when significant, but not excessive, water level changes occur. The maximum measured line loads for these two cases are 85 kN/m and 374 kN/m, respectively. Preliminary analyses have shown that ice loads can be affected significantly by the reservoir shape when the reservoir sides are significantly softer than the dam.
