Abstract: This paper describes studies conducted by Alcoa Inc. (Alcoa) to evaluate the expected performance and support the design of a pier-type structure to control ice jams on the lower Grasse River located in Massena, New York. We build upon numerous studies and investigative work conducted following the 2003 ice jam event on the lower Grasse River. The information presented herein provides a basis for the evaluation and design of a pier-type ice control structure (ICS) at “T6.75” a site located 0.75 miles downstream of the Massena Rapids. Specifically, this paper: 1.) Identifies a range of options considered for controlling ice jams in the river, and 2.) Summarizes the results of the studies evaluating the technical feasibility and design development of a pier-type ICS to control ice jams and ice related sediment scour in the lower Grasse River. The findings presented in this paper represent work in progress only, as the final remedy at the Grasse River site has yet to be chosen.
