Soil Erosion Affects Our Lakes and Streams!
Why Should I Be
• Otsego County is comprised of mostly sandy soils. In addition to being highly
permeable, which poses a risk for groundwater contamination, sandy soil is
also highly erodible.
• Construction is one of the top causes of soil erosion in Michigan. By using the
appropriate erosion control practices the amount of sediment entering lakes
and streams can be greatly minimized.
• When sediment does enter a lake or stream it can be harmful in 2 ways:
•) Suspended sediment makes water turbid and can cause abrasion of
gill membranes of aquatic organisms and impair feeding.
•) Deposited sediment can destroy habitat for bottom-dwelling
organisms. It fills in gravel on the bottom that is important for species
like trout when spawning. Sediment stops the flow of oxygenated water
through the gravel which suffocates eggs and prevents the removal of
