Preliminary Lake Use Evaluation for the Chain of Lakes (2014)

The purposes of this 2014 study are to identify which potential lake uses may be more suitable for individual former quarries – especially where conflicting proposed alternatives uses may exist – and provide a framework for evaluating proposed uses as lakes are transferred to Zone 7 ownership. The evaluation generally does not preclude any given lake from distinct uses, but instead provides a tool for examining the benefits or impacts associated with a proposed use.
