Lake Ontario Park

May 20, 2017 — The Cataraqui Region Conservation Authority (CRCA) has updated its Flood Statements today for Inland Lakes, Lake Ontario and the St. Lawrence River.

Inland Lakes, Gananoque River Watershed – Flood Watch Downgraded to Normal Status

By this upcoming weekend the water levels in these lakes will have fallen to or below high spring levels.

Removed from Watch – at high spring levels by this weekend: Charleston Lake

Inland Lakes, Cataraqui River Watershed – Flood Warning Update

The Flood Warning continues for several lakes in the Cataraqui River Watershed. Although many lake levels remain very high, conditions continue to improve gradually as levels slowly drop. Some lakes have been removed from our flood messaging because they have dropped to high spring levels.

Locations still in Flood Warning status:

Colonel By Lake, Cranberry Lake, Devil Lake, Dog Lake, Kingsford Lake, Newboro Lake, Opinicon Lake, Sand Lake.

Removed from Warning – at high spring levels: Buck Lake

Water managers continue to conduct operations to minimize the effects of the high-water levels and pass flows down through the system.

Lake Ontario and St. Lawrence River – Flood Warning Continues

Lake Ontario and the St. Lawrence River remain under a Flood Warning.

The International Lake Ontario – St. Lawrence River Board is continuing operations and increasing outflow to minimize flooding and erosion impacts when possible.

The Board reports that the current water level for Lake Ontario is 75.86 m as of May 17, 2017.

Water levels will remain high for some time and increases are possible, particularly during periods of heavy rain. Level increases are expected to be much less than seen since the start of April and The Board predicts that water levels will start to gradually decline at some point over the next several weeks.

The water level measured today at Kingston is currently 75.8 metres which is just 0.2 metres below the Lake Ontario 100-year flood elevation of 76.0 metres.

The current level of the St. Lawrence River measured at Brockville is 75.5 metres. This is just 0.3 metres below the 100-year level of 75.8 metres in that area along the River.

Kingston – 613-544-9264 for real time water levels

Brockville – 613-345-0095 for real time water levels

Residents in flood prone and low lying areas may experience further water level increases through May, and possibly into June if wet weather continues.

Flooding and erosion damage from high waves is possible during periods of strong winds.

The CRCA is urging residents to pay close attention to forecasts for approaching storms with high winds from the southeast, south or southwest, and note that the above mentioned 100-year flood elevations do not include wave uprush (increased water levels resulting from high waves).

For up-to-date wind and wave forecasts visit the following links to marine forecasts:

Property owners are also reminded to turn off electricity to buildings or structures in flood prone or low lying areas and to move gasoline and other chemicals to higher ground. Any work along shorelines (e.g. placement of fill, armour stone, etc.) will require a permit from the CRCA. Call our office or visit our website for further information.

Municipalities have been advised and are assessing the situation to determine appropriate response. They can be contacted to inquire about physical/material assistance (e.g. sand and sand bags).
