With a hole in the weather Wednesday and Thursday, everyone knows more rain is coming and there isn’t much anyone can do except wait for it to drain away, and maybe pile sandbags.
“With the ground already saturated, there may be potential for some local flooding,” Environment Canada warned Wednesday, to no one’s surprise.
Gatineau remains the hardest hit, especially in areas near Leamy Lake.
By Wednesday morning, as Gatineau faced flooding typically seen on average every 20 years, the city had closed more roads and evacuated 112 people from 48 homes. The evacuations remain voluntary, and the city says no one is in danger.
As well, gas service had been shut off as a precaution to 108 homes. There are now 31 sections of streets or walking paths closed and 16 more open only to local traffic.
With up to 50 millimetres of rain in the forecast for Friday and showers on the weekend, the city is still expecting water levels to rise in some areas by 13 to 15 centimetres.
One of many roads that are newly closed is Saint Louis at the des Draveurs Bridge. The street is closed from Moreau to the bridge, which carries Highway 50. The eastbound on-ramp is also closed. There are police on scene to direct people through detours.
By early morning the city had filled 33,760 sandbags and made them available at 11 distribution sites. More than 30,000 empty bags are available to be filled.
The Rideau River system had been dropping since its peak in early April but has risen with the rain early this week and is expected to rise more with further rain.
An issue is that many of the lakes upstream — the “reservoir” lakes — are full. Bobs Lake has remained high since the spring runoff. The other lakes, Wolfe, Upper Rideau and Big Rideau, are already above the level at which some damage may be expected.
With more rain coming, that leaves the Rideau Valley Conservation Authority with the task of adjusting the flow of water out of these lakes, which will affect levels in the section of the river from Kars to Kemptville.
The conservation authority says that “adjustments at the various dams on the system are being done to counter the rise. As the adjustments are made, residents can expect to see fluctuations in levels as the rain runoff passes through the watershed.”
Britannia Village area, a frequent trouble spot in many high-water years, remains largely dry thanks in part to a new berm built by Ottawa and the conservation authority.
High west winds were driving waves on Lac Deschênes against the Britannia shore, but the barriers were holding. At the Britannia Yacht Club the waves were washing up against a line of plastic sandbags along an outdoor patio, and the water was visibly higher than it had been on Tuesday.
The Mississippi Valley Conservation Authority had ended its flood watch days ago, but water levels have risen again. It notes: “Levels on the upper lakes will remain high for at least the next week and any significant rainfall during that period may aggravate current conditions. Water levels and flows along the lower Mississippi River will remain high as this water is passed through the system.”
The South Nation Conservation Authority says: “Severe flooding is not a concern at this time; however, nuisance flooding in low-lying areas may be observed. Furthermore, potential for blocked storm drains, catch basins and culverts are very high which may also cause localized flooding.”
More to come.
