Abstract/Description or Keywords Lakes offer opportunities for residential and recreational use. Shoreline developments, however,
can negatively affect fi sh and fi sh habitat, the foreshore, and the very setting that makes them so
attractive to people in the fi rst place. This is particularly true for lakes that have fl uctuating water
levels.
The vulnerability of the lakeshore to erosion is varied, but erosion protection measures tend to
be applied in a blanket approach—an approach that is neither cost effective, environmentally
friendly nor typically required. This report presents a method for determining and mapping the
shoreline erosion hazard around a lake and suggests appropriate protection measures. It is meant
to help lakeshore owners and planners choose where to place their protection efforts, and offers
alternatives that will help maintain the ecological integrity of the land-water interface, while
protecting property and property owners. The fi rst part of the report describes the methodology
for determining and mapping lakeshore erosion hazards; the second is a conceptual tool kit for
dealing with erosion where it occurs in a manner that retains some of the biological integrity of
the lakeshore. The report does not specifi cally address individual concerns, nor is it meant to
restrict the possibility of other innovative designs not considered in the tool kit.
