Impacts of Shoreline Modification
Shoreline modification has many negative effects on the Great Lakes. The structures have blocked the lake's ability to rinse its shoreline, and reduced the transport of sand along the waterfront has been limited. In building these structures and modifying the natural lakefront valuable aquatic habitat has been destroyed. Traditional sources of sediment have been eliminated through shoreline armoring, while in other places the erosion rates have accelerated.
- Silt and clay have increased inputs due to the clearing of lands and shoreline construction
- Sand and gravel have decreased inputs due to flood control
- Shore erosion has remained rather constant, although certain locations have changed dramatically
We now decide where the beaches are, where the erosion is from, and to, albeit not always anticipated, and we must be willing to suffer the consequences when nature doesn't work the way we want it to. We have to be worried, that the increased shoreline roughness doesn't create cesspools that capture sediment. Overall projects have too many overseeing authorities/people to pass by, yet none are really focused on the overall Lake health.
