Seven beaches across Niagara have been posted as 'unsafe to swim.'
Three of those beaches, including Lakeside Beach in St.Catharines, Charles Daly East in Lincoln and Nelles in Grimsby, are on the list because of high water levels.
The region says those areas are unsafe for swimming due to water levels, and the water will not be tested until water levels drop.
Beaches which have been tested and posted due to high bacteria levels include Waverly Beach in Fort Erie, Queen's Royal in Niagara-on-the-Lake, Humberstone Centennial Park and Sherkston Wyldewood Beaches in Port Colborne.
Meantime, Lakeside Beach reopens today after severe flooding this year.
