SVCA issues a flood watch

The weather forecast for the next several days calls for temperatures well above freezing with some days above 10 degrees Celsius, and night-time temperatures generally above zero.
Scattered showers are also possible Thursday.
For these reasons, the Saugeen Valley Conservation (SVCA) has issued a flood watch throughout the watershed area, effective now through the weekend.
The high temperatures and rainfall will result in further melting of the snow pack and produce increased runoff into watercourses.
The snow pack has been steadily declining over the past two weeks, but in many areas such as forests, there still remains an above-average snow depth for this time of year.
Throughout the SVCA watershed, water levels in watercourses are expected to gradually rise through the rest of the week and into the weekend. Significant flooding is not expected at this time, but flooding in the traditional low-lying flood plain areas can be expected.
Most of the ice has already moved off the
watercourses and so large ice jamming is not anticipated at this time.
Nevertheless, there may be localized blockages at some watercourses and
snow or ice could still impede flow in ditches and drainagechannels.
As of the beginning of April, the average water content in the snow pack was in the range of 13 centimetres (five inches). This amount is well above the long-term average for the time of year.
As such, there is substantial meltwater that will be moving through the system over the next week or so.
Due to the elevated flows in the rivers and streams and unstable streambanks, the public is advised to stay away from area watercourses.
SVCA staff will be monitoring conditions as they evolve, and further statements will be issued as warranted.
This message is in effect until 11 a.m. Monday, April 14, unless a further statement is issued.
