Flood warning for the Village of Grand Valley and the St. Jacob Low Level Bridge in Woolwich Township; Flood watch for the remainder of the Grand River watershed
Warm temperatures moved into the Grand River watershed yesterday and overnight temperatures remained well above freezing. This combined with very mild temperatures today has triggered much of the remaining snow pack to melt. Rivers and streams across the watershed have responded. In the northern portion of the watershed, levels started to rise overnight and are continuing to rise today.
Grand River Grand Valley
Based on current flow conditions, the GRCA is issuing a flood warning to the Village of Grand Valley to close Hwy 25 through Grand Valley. Levels are expected to flood the low lying portion of Hwy 25 through Grand Valley later this afternoon and the highway will likely remain closed well into the evening.
Conestogo River – St. Jacob Low Level Bridge (1505 Three Bridges Road, Woolwich Township)
Access to the St. Jacob Low Level Bridge is currently blocked due to flooding, and it will remain closed upstream of St. Jacob at 1505 Three Bridge Road through the weekend until flows in the Conestogo River recede.
Flood Watch - Grand River Watershed
A flood watch is issued for the Grand River watershed. River flows will remain high through the weekend and into next week. No major flooding is anticipated at this time; however, flooding of low lying areas adjacent to the river that normally flood can be expected.
The major reservoirs at Belwood, Conestogo, Guelph, Luther, Woolwich, Laurel, and Shades are being used to manage runoff and reduce downstream flooding.
Rain is in the forecast for Friday as a new weather system moves into the watershed. Runoff from rainfall will further increase water levels. While major flooding is not anticipated, conditions will be monitored closely and additional messages issued as needed.
This message will remain in effect until noon on Monday, February 27, 2017.
