...slightly off-topic but what the heck....
...not having anything better to do, I googled the defunct Laconia waste water treatment plant and came up w/ a 11/14/07 Laconia Citizen article about Wolfeboro and Tuftonboro having a discussion about Wolfeboro discharging treated waste water into a Tuftonboro creek that flows into Lake Winnipesaukee.
Anyway, it mentions that the Laconia treatment plant (now) next to the Winnisquam boat launch ramp had been the source of large algea blooms in Lake Winnisquam in the 1970's and 1980's because the treated water, discharged into the Winnipesaukee River close to Lake Winnisquam, had been treated but still contained nitrogen and phosphorus.
...so, how about that...?
I suggest that a slots casino hotel be built on that Laconia waterfront peninsular spot and it can advertise "come to the wastewater treatment plant and win big
