A low pressure weather system is moving throughout southern Ontario, including the Kawartha Conservation watershed. Up to 25 mm of rain and double digits temperatures are predicted for the watershed by Environment Canada over the next two days.
At this time, local rivers and streams are flowing within their banks. With the ground surface throughout the watershed being either saturated or partly frozen, its ability to absorb additional runoff is limited. In these circumstances, the forecast rainfall, in combination with melting of remnants of snow, will produce additional runoff. As a result, water levels in watercourses within the Kawartha Conservation watershed are expected to increase moderately. Accumulation of water in low-lying areas, road ditches, and areas with poor drainage will likely occur.
While no flooding is anticipated at this time, local watercourses will flow at higher than usual water levels and velocities; riverbanks will be very slippery and unsafe. As a result, all local rivers, streams, and lakes should be considered extremely dangerous. Kawartha Conservation is warning all residents to stay away from water bodies, as well as water structures such as bridges, culverts, and dams.
Trent-Severn Waterway officials report that the water levels in the larger lakes across the Kawarthas are still lower than usual for this time of the year due to low inflows during the winter months combined with a slow spring freshet. The TSW monitors this situation closely and undertakes dam stop logging operations as required.
Ministry of Natural Resources and Forestry, Bancroft District, oversees the flood forecasting and warning operations for the Burnt and Gull River watersheds. A Watershed Conditions Statement – Flood Outlook is in effect for those areas.
This Watershed Conditions Statement - Water Safety will be in effect through Monday, April 13th, 2015 within the Kawartha Conservation watershed.
Kawartha Conservation will continue monitoring local watercourses 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.
Flows on all small creeks and streams across the watershed region are expected to increase over the Easter weekend, however temperatures well below freezing on Saturday and Sunday evenings should moderate this runoff. At this time, all water levels and stream flows are low for this time of year, and we anticipate an ongoing gradual spring runoff with few, if any, problems.
