Environment Canada predicts that another moisture-laden system will track across southern Ontario Wednesday night through Thursday, bringing significant precipitation, including a thunderstorm risk, strong winds, and very mild temperatures. Between 20-30 mm of rain is forecast for the Kawartha Conservation watershed, with up to 50 mm farther to the north, an area that includes the Burnt River and Gull River watersheds.
Water levels in local rivers and streams are still elevated responding to this Monday’s rain event. The ground is saturated or partly frozen, with limited capacity to absorb additional precipitation or snow melt. While snow cover has melted within the Kawartha Conservation watershed, the Ministry of Natural Resources and Forestry reports that a significant amount of snow is still present within the upper reaches of the Burnt and Gull rivers’ drainage areas.
Under these watershed conditions, expected precipitation will generate a substantial amount of runoff that will further increase water levels and flows in local rivers and streams. While no major flooding is anticipated within the Kawartha Conservation watershed at this time, water accumulation will occur in low-lying areas, road ditches, and areas with poor drainage. Rivers and streams may exceed their banks in some locations and spill onto the floodplains.
In these circumstances, all local watercourses and waterbodies should be considered extremely dangerous. Kawartha Conservation is warning all residents to stay away from all water bodies, as well as water structures such as bridges, culverts, and dams. Children should be warned of dangerous conditions and caregivers should maintain a close watch on children who are outside.
The Ministry of Natural Resources and Forestry, Minden office, has issued a Flood Warning for the Burnt and Gull Rivers, advising that ”incoming rainfall will result in exacerbating the already high water conditions and is likely to lead to minor flooding in vulnerable areas”.
Municipalities are advised to monitor areas known for minor flooding and be prepared to respond to high water situations as they occur. Residents are advised to contact their municipalities should a flood threat develop. Local municipalities are first to respond to and assist with flood emergencies.
Trent-Severn Waterway officials are monitoring the current situation closely and are adjusting dam settings accordingly. While Balsam Lake and Cameron Lake have reached their full navigations levels, Sturgeon and Pigeon lakes are still below. Dams in Fenelon Falls and Rosedale are open to accommodate increased flows of Burnt and Gull rivers.
This Flood Watch will be in effect until Sunday, April 3rd 2016. Kawartha Conservation will continue monitoring local watercourses and watershed conditions and notify the public and municipalities within its watershed jurisdiction of any changes. If you are aware of or have concerns about flooding, please contact Kawartha Conservation at 705.328.2271 or 705.344.0155 after hours.

A Flood Watch is a notice that flooding is possible in specific watercourses or municipalities. Municipalities, emergency services, and individual landowners in flood-prone areas should prepare
