Flooding is expected in the Rideau River watershed today and through the weekend. Previous rain from the beginning of the week has increased water levels throughout the watershed. Parks Canada staff have been making adjustments at all dams to reduce the water levels with some success. However, there is still excess water in the Rideau Canal reservoir lakes. Christie Lake on the Tay River, is expected to have further flood issues as water is released from Bobs Lake to relieve ongoing high water there. Releases from Big Rideau Lake will have to be made today which will increase flows downstream.…
