Discussion as of 09/17/2021:
Toronto elevation is expected to fall steadily to about 1212 on October 1 and 1204 on November 1. Swinging Bridge elevation is expected to fall steadily to about 1063 on October 1 and then level off or increase in November. Mongaup Falls elevation will likely remain between 929 and 934 through November. The elevation at Rio will be held between 808 and 810 into October until the flashboards, which were damaged in the flows from Ida, can be repaired.
