Lower Trent Conservation advises local municipalities and the public that a Flood Warning is now issued for Rice Lake and the Trent River from Hastings to Trenton.
LTC officials say during this time, high water levels, unsafe banks or other factors could be dangerous for recreational users and waterfront landowners. This Flood Warning Statement is intended as an update to the Flood Watch issued on March 31.
The Trent River system is in full spring freshet with the warming temperatures melting the snowpack in the larger Trent River watershed, which includes the Haliburton tributaries, reservoir lakes, the Kawartha Lakes and the Otonabee River.
There is still significant snowpack remaining in these northern areas and forecasted rainfall of 25-30mm is expected Sunday, with an additional 5-day period of sustained rainfall accumulation of up to 60mm, with the potential for thunderstorms to increase the intensity on a localized scale.
This will lead to significant melting of the remaining snowpack, which in turn will increase flows and levels in the Trent River. Temperatures will also continue to increase above freezing, potentially melting the remaining snowpack found in the larger Trent River watershed along with the forecasted rain.
Outflows from the Kawartha Lakes, through the Otonabee River, into Rice Lake and down the Trent River are expected to increase over the next week as the melted snow and rain flows through the Trent River system.
As well, flows into the Trent River from the Crowe River are currently elevated and trending upwards.
Because of these increasing flows and water levels continuing to rise, this Flood Warning for Rice Lake and the Trent River is now being issued.
High water levels could cause flooding of driveways, access roads or buildings located in low-lying areas. Residents should ensure their sump pumps are working and secure personal property (boats, docks, etc.) along riverbanks.
While the potential dangers presented by rivers, small streams and open ditches never cease to exist, they are of particular concern during these conditions. As a result of the high flows, there is
also potential for ice damage where accumulation is still present along the banks of the river.
Water currents could be strong and temperatures are cold. Parents and caregivers are advised to keep children and pets away from all waterways. Additionally, areas around dams, culverts and bridges should be avoided at all times.
