Summary of shoreline type (natural or hardened) along the Canadian Great Lakes; data is part of the Overall Assessment of the State of Nearshore Waters.
<DIV STYLE="text-align:Left;font-size:12pt"><DIV><DIV><P><SPAN>This data was derived as part of the Overall Assessment of the State of Nearshore Waters. Across the Great Lakes, much of the nearshore, waters edge or back of beach has been altered with engineered structures or artificial material. Hardened shorelines reduce coastal resiliency by altering sediment dynamics, accelerating erosion, increasing water turbidity & destroying local vegetation. Shoreline hardening is assessed by determining the percent of the total length of shoreline in a Regional Unit that is hardened.</SPAN></P><P><SPAN>The shoreline of </SPAN><SPAN>the Canadian Great Lakes </SPAN><SPAN>has been delineated as either "natural" or "hardened" based on the following definitions:</SPAN><SPAN /></P><UL><LI><P><SPAN STYLE="font-weight:bold;">Natural Shoreline</SPAN><SPAN>: no engineered or artificial structures in the nearshore, at the waters edge, toe of bluff, backshore or back of the beach; rising and falling water levels result in natural changes in the shoreline position; wildlife usage and vegetation migration upslope and downslope can occur unimpeded; natural vegetation communities, consistent with local conditions, are generally present along the shore.</SPAN><SPAN /></P></LI><LI><P><SPAN STYLE="font-weight:bold;">Hardened Shoreline: </SPAN><SPAN>the nearshore, waters edge, toe of bluff, backshore or back of beach has been altered with engineered structures or artificial material (e.g. offshore breakwaters, lakefill, groynes, seawalls, revetments, dumped concrete rubble, artificial channels, dikes, etc.); natural shoreline processes are altered, and native vegetation communities are generally absent.</SPAN></P></LI></UL><P><SPAN>Best available, most recent aerial imagery was used for the delineation, at a scale of approximately 1:2,000. </SPAN></P><P><SPAN>Low Stress: <25% shoreline hardening</SPAN><SPAN>; </SPAN><SPAN>Moderate Stress: 25-50% shoreline hardening</SPAN><SPAN>; </SPAN><SPAN>High Stress: >50% shoreline hardening</SPAN></P></DIV></DIV></DIV>
