Huge walls of super sandbags in Brandon are striking fear in residents about the severity of expected spring flooding this year.
Thousands of the so-called super sandbags, 100 times larger than a regular sandbag, line the 18th Street Bridge to protect low-lying areas from being washed out.
Provincial crews are stacking them two layers high for a two-meter tall wall.
That has caused some people to worry about just how high the floodwaters are expected to be, said city spokesman Bryce Wilson.
The city has received several calls from residents this week.
"You kinda drive by the Corral Centre (shopping mall) there and you look at them and you wonder, 'holy smokes that's high. I hope the water doesn't get that high,'" he said.
But Wilson said the first layer is designed to take the potential worst case river level. The second layer is to allow for 'freeboard' wave action.
The wind can churn up waves a metre high without fears of the floodwaters breaching the dike, Wilson said.
A notice has been posted on the City of Brandon website to explain the rationale behind the construction and allay fears.
"This was the most efficient way to add a generous level of freeboard and does not indicate an increase in the outlook levels for the river in this area," states the notice.
