An investigation was conducted to analyze the tainter-gate, sluice-gate, ice-chute, and head-gate monoliths of Brandon Road Dam to determine if they meet present-day stability requirements. In general, the stability analyses for these monoliths were performed for the following case loadings a normal operation, b normal operation plus ice, c normal operation plus earthquake, and d flood condition. In the analyses of the tainter-gate, sluice-gate, and ice-chute monoliths, the total monolith for each was analyzed and determined to be adequate in stability. However, due to overstress between the main body and the downstream apron of the structures, the aprons of each were considered ineffective and therefore, were eliminated from the analyses. In the stability analyses of the tainter-gate, sluice-gate, ice-chute, and head-gate monoliths, the results showed the monoliths to be inadequate against overturning stability for all case loadings. The head-gate monoliths were also inadequate for resistance against sliding. To correct these deficiencies, prestressing was recommended and the details are presented for each of the monoliths. The monoliths were reanalyzed to include the recommended prestressing and were determined to be adequate in stability for all case loadings.
