Recreation

The Nith River is flat water with a few riffles, but rain can significantly increase the flow rate. In the early spring the water level has risen to nearly 1000 cm2/s, this causes major flooding in the flat regions upstream such as in and around New Hamburg. The Nith offers excellent paddling conditions in April, including a set of level 3 whitewater rapids as the Nith enters Paris, yet by May, the flow rate drops below 5cm2/s and becomes unsuitable for paddling.

The secluded banks, mostly formed of farm fields, are a popular spot for summertime party goers.
