High tides near Wolfville. File

By Wendy Elliott


High tides will double this week from the heights experienced last week in the Minas Basin.

Tim Webster of the Applied Geomatics Research Group at NSCC’s Centre of Geographic Sciences suggests, “at the time of high tide, we’re vulnerable.”

“The more awareness there is the better prepared people can be.”

Generally, higher tides are evident when the moon’s orbit takes it closer to the earth. A new or full moon also adds an impact. The new moon this month takes place Nov. 13.

Tomorrow, with the moon at perigee, the tide height in the Minas Basin is projected to reach 15.9 metres. On Nov. 15, it could be even higher at 16.2 metres.

Barring a storm surge at the same time, the dykes should be capable of withstanding such tides. However, there won’t be much room to spare, perhaps a foot or two. A storm surge coincident with the high tide could potentially overtop the dykes.  

Sherman Williams of the Blomidon Naturalists Society is expecting pretty healthy tides. The Avonport resident will watching to see where the wind is blowing from as well.

“South winds can elevate the tides significantly,” he said. Williams noted that the tides were high in October too.

According to Webster, a deep low pressure, combined with wind, could help push water over dykes, especially with waves. The storm surge in New York during hurricane Sandy was four metres. During the famed Saxby Gale of 1869, it was about two metres (6.5 feet) in the Bay of Fundy.

The dykes at Wolfville harbour were last topped in the 1970s, but in recent years, water has pushed to Main Street, near Willow Park.

Webster says what happens will depend on the wind direction. His team has recently prepared elevation data about dykes for municipalities like Lunenburg, Yarmouth, Windsor and Wolfville.

Hopefully, he said, we won't have a series of combined weather factors and it will simply be a sightseeing opportunity.

    I grew up less than 100 meters from Willow Park, or the "Duck Pond' as it was known prior to 1967. During my childhood the area was flooded with tidewater at least three times. The aboideau under the railway was unable to hold it all back and it physically flowed over the DAR tracks. I can recall at least one instance where the Wickwire Dykeland east of Dyke Lane was inundated since its completion in 1960. Minas Basin is predisposed to the effects of tidewater surge, and as the drowned forests around the basin attest, tidewater conditions and ranges have varied considerably in the past few thousand years. There is no reason to believe that this won't be normal in the future. Shoreline landfills also subside over time, making them prone to inundation on spring tides where the BOF 'windscape' favors water piling up into the head of the bay.
