TAY RIVER WATERSHED, June 22, 2012 — The Rideau Valley Conservation Authority (RVCA) has started a floodplain mapping project of the
Using the latest hydrologic and topographic data and well-established practices in water resources engineering, the 1:100 year flood flow, regulatory flood levels and corresponding floodplain limits will be estimated throughout the study area during this project.
Floodplain limits are determined by estimating the flood flow at various points along the river, using any available historical streamflow and water level data collected over the years, along with state-of-the-art watershed modeling tools.
Historical records of past flood events, news clippings, photographs, and even anecdotal stories can be helpful in confirming the reasonableness of our calculations and resulting floodplain mapping. Local residents with this kind of information are encouraged to share their knowledge with RVCA’s
The last floodplain mapping in this area was completed in 1981and covered the river from
Once the technical work is completed and floodplain mapping has been prepared, a public information session will be held (Fall 2012) where feedback from the public will be invited. Any new information or comments received will then be taken into consideration in further refinement of the mapped flood plain limits. A Report will then be presented to the RVCA Board of Directors, recommending formal adoption of the flood plain limits and their use in RVCA’s land use planning and development review services.
