Lake Saroma is an inland sea-lake on the Sea of Okhotsk. As the lake's environment is suitable for aquiculture, it is widely used for natural sea farming.Ice floes usually reach Okhotsk Sea coast of Hokkaido from late January through early February. When ice floes arrived before Lake Saroma had sufficiently frozen up, the inflow of ice into the lake damaged aquiculture facilities. As a countermeasure for this, construction of ice booms to control ice floes began in 1994 and 10 spans out of 13 planned have since been completed.In this study, the effectiveness of ice booms in controlling ice floes in an actual sea area is confirmed, factoes concerning the tension of the main wire, an important point in design, are analyzed using research results, and the design and actual values are compared.
