Kemptville Creek Flood Risk Mapping - Floodplain Delineation Revision 1 (June 3, 2011)
With relatively minor rain forecast for the coming week and the flood waters in decline, the RVCA is withdrawing the Flood Watch that has been in effect for the last week.
Water levels are still above normal but continuing to decline. The 3-day rainfall of 35 millimetres presently forecast for Wednesday through Friday in eastern Ontario is expected to cause a pause in the decline. Periods of heavier, localized rain may fall in thunderstorms but no significant impact is expected at this time.
Waters have receded from the North Gower area where serious flooding along Stevens Creek occurred last week. Residents continue to be faced with the cleanup.
It will continue to be risky to be around dams in the Rideau system due to the higher than normal water. Boat wakes need to be controlled with slower speeds. Caution around the water for everyone is advised.
For water level and flow information in the Rideau system as well as the Ottawa River, visit the RVCA Streamflows and Water Levels webpage at: https://www.rvca.ca/watershed-programs/reporting/streamflow-water-levels.

Floodwaters Receding Slowly
As Stevens Creek levels slowly decline, residents of North Gower continue to deal with water in basements and on streets as a result of record setting rainfall.
On the Rideau, minor flooding of low-lying areas on the Long Reach have access issues similar to what often occurs in the spring. Parks Canada staff are doing strategic dam operations to get water levels down throughout the Canal system with as little impact as possible.
With high flows passing through the dams, boaters are advised to stay well away. Also with high waters, boat wake becomes a problem causing damage to shorelines. The best choice is to leave the boat tied up or out of the water until normal navigation levels are reached. Also, boats and docks need to be well secured to avoid floating away.
No significant rain is presently in the forecast and, therefore, the decline in levels can be expected to continue over the next week. However, with the ground saturated and little capacity for infiltration, residents need to be aware that another bout of rain could cause runoff to go directly to the streams and flows to rapidly rise again.
All residents need to be aware of the dangers around all waterbodies especially close to the dams and locks in the Canal system.

City of Ottawa Hazard Mapping Project
The Rideau Valley Conservation Authority (RVCA) is conducting several hazard mapping studies on watercourses within the City of Ottawa and the RVCA area of jurisdiction. For some watercourses, old mapping will be updated; and for others, hazards maps will be created for the first time.
