UPDATE: Never mind, DCR says.
Paul Levy considers a DCR proposal to try to stop people from swimming across the historic kettle hole:
Why now? [Open-water swimming] has existed at the lake for decades. What is prompting this proposed change that didn't exist years ago? (I guess there were some similar thoughts in 2010.) Those engaged in OWS are adults who understand the risks. If the issue is the budget impact of the very occasional rescues, simply put in place the kind of rule that exists in the mountains in some jurisdictions: If you need to be rescued, you pay for it.
