Cedar Lake erosion restoration Illinois : A 2004 study found extensive erosion along Cedar Lake, with about 200,000 feet of shoreline, roughly four, fifths of the lake's shore, classified as at least slightly eroded. Many areas had severe erosion.

Stabilization efforts followed through Clean Water Act (CWA) Section 319(h) projects aimed at reducing sediment and nutrient loading to Cedar Lake and lowering the pollutant load reaching Cedar Creek. Projects in 2009, 2015 and 2021 focused on eroding shorelines and gullies.
