If you have been near the Rideau and Ottawa rivers this spring, you may have noticed upright white meter sticks in the water. These simple water gauges are a new tool that have had a big impact on the City’s flood preparations this year.
Ryan Polkinghorne, a nine-year veteran with the City of Ottawa, is a program manager in the Stormwater Management Branch. This year, one of Ryan’s duties was to install water gauges in areas that are vulnerable to flooding and monitor and evaluate the readings.
One of the lessons learned from the 2017 floods was that the City could improve how it monitors water levels. Earlier this year, the City installed 19 water gauges: four on the Rideau River and 15 along the Ottawa River.
A challenge with the new water gauges is to determine the timing and locations of installation. The window of opportunity is small: the water gauges can’t be installed too early in the season, as melting ice flows could break them; they also need to be installed before the spring thaw. The City’s stormwater management team worked closely with parks and roads staff to find the best locations and assist with monitoring.
Water gauges enhance the flood forecasting work led by local conservation authorities. City staff work in partnership with the Ottawa River Regulation Planning Board and regional conservation authorities to share data and validate current flood-mapping models with the goal of improving future plans.
The result: an immediate and accurate way to measure water levels, which residents didn’t think were going to get as high as they did. The power of Mother Nature can be very humbling.
No single body is responsible for monitoring water levels along the Ottawa River. With two provinces and numerous organizations in charge of their own small part of the river, getting everyone together can be challenging. However, Ryan and the rest of the City’s stormwater management staff are trying to make sure the City has the right tools in place to prepare for the spring thaw and its potential impacts.
