9/21/2023 0 Comments Dredging a pondAverage annual ground-water recharge in the study area is about 13 inches. Ground water from glacial deposits is the source of most of the water flowing in spring ponds and streams in the study area. Maxwell Pond, which was not dredged, was a hydrologic control to aid in distinguishing changes produced by dredging from those that were natural. Sediments were dredged from Sunshine and Krause Ponds. Three ponds, Maxwell, Sunshine, and Krause Ponds, in northeastern Wisconsin were studied. The purpose of the study was to determine the hydrology of selected spring ponds and the effect that dredging has had on the ponds. Spring ponds (small spring-fed bodies of water) are natural features of some glaciated areas and have a continuous flow of ground water entering through their bottoms and exiting through surface outlets.ĭredging has been used to restore ponds that have been filled in part or totally by sediment.
