![]() If a pond is left undredged, the water becomes shallower and has a higher average temperature, McElhany said. Dredging increases the depth of the water body and helps reduce exposure of fish, wildlife and people to contaminants that enter waterways in cities and industrial areas. The dredging process removes sediment and debris from the bottom of lakes and rivers that have built up over time, according to the National Oceanic and Atmospheric Administration. The consultant will also develop a process to determine which water bodies should be prioritized and conduct surveys of park land to determine how much sediment needs to come out of the water, McElhany said.

Goose droppings in the pond add to sediment, and droppings on the side of the pond get washed in, he said. McGee placed some of the blame for the need for dredging on the sloping shoulders of Canada geese, once migratory birds that, for decades, have lived in the park year-round and feast on the vegetation. “It could range from $60,000 to $160,000, depending on all they hope to accomplish in addition to just dredging,” he said. ![]() How to shore up the banks and whether to plant natural grass or erect walls around the ponds are costly questions surrounding the dredging itself, McGee said later “We spent $50,000 to dredge that and I suspect it’s significantly more than that. The last time it was dredged was in the mid-’80s,” he said. “It’s to the point where we’re going to have to dredge Kohler Park again.
