Contractors to survey local ponds to help keep Lethbridge waterways healthy
Officials with the City of Lethbridge say you might notice some activity around stormwater ponds over the coming days.
They say it’s all part of keeping Lethbridge’s waterways clean and healthy.
Starting July 15, the city says contractors are surveying 22 ponds throughout the community. The work involves a small boat cruising across pond surfaces to collect sediment samples, snap photos and map out the shape of the pond bottoms.
The city says ponds play a big role in managing stormwater runoff. Officials note they collect materials like dirt, gravel, oils and nutrients from streets and sidewalks. But over time, the city says all that buildup can reduce how much water the ponds can hold and affect the quality of water that flows into the Oldman River.
