Otonabee Conservation has issued a flood warning for local waterways as rain and snow continue to fall over Peterborough and area.

The conservation authority issued a flood watch earlier this week.

With as much as 35 millimetres of precipitation since Friday, water levels and flows in local rivers and creeks has increased, the conservation authority reports.

The warning, which is issued when flooding is imminent or occurring, affects Peterborough city and county, Cavan Monaghan, Asphodel-Norwood, Otonabee-South Monaghan, Trent Hills and the City of Kawartha Lakes.

The forecast calls for freezing rain, ice pellets and snow Saturday afternoon and evening, turning to rain Sunday as temperatures rise.

Precipitation levels could reach 50 millimetres Sunday, with another 10 to 20 millimetres Monday.

Inflows to the Kawartha Lakes have increased, as have outflows, which have risen from 180 cubic metres per second to 250 cubic metres per second in days.

In areas near the Otonabee River, the Indian River, the Ouse River and tributaries of the Kawartha Lakes, Otonabee Conservation reports that the ground is saturated and can't absorb additional rainfall. This could lead to pooling and ponding near waterways and in low-lying areas with poor drainage. Area creeks - Squirrel, Baxter, Cavan, Jackson, Rays, Meade and others - could see water levels overflow their banks.

South of Peterborough, the Otonabee and Trent rivers and Rice Lake have seen increase flows as water comes out of the Kawartha Lakes, which could lead to flooding in traditionally flood-prone areas.

Otonabee Conservation is monitoring the situation and will issue updates as warranted.
