Last time I used the pool there, the water temp must have been about 70-degrees which definitely feels cold what with it being indoors without any sunshine to help warm you up. It ain't like no lake with the outdoor natural sun, it's totally indoors ....ain't no way around that....so what it needs is some good warm water, and warm room .... push up the heat!
Believe the NH-DES has an employee who goes all around the state, shows up unannounced, to do water testing on public swimming at lakes, pools, and hot tubs.

"The state currently monitors conditions at more than 1200 bathing facilities."
In New Hampshire, believe that public pools have a maximum temperature of 85-degrees, and public hot tubs have 104-degrees, plus they get tested for water quality cleanliness.
And, slightly off topic here ........ but, what the heck! ......... foam noodles come in about five different sizes.... from skinny to huge .....
