both correct on bridge. RR bridge has had about 6-8 foot of clearance so far this year. I'm about 7 feet tall from waterline and have not needed to call for a raise yet this year. ( i can drop my top to sneak under also).

There is a Phone # on the sign at the bridge if you need it raised open. Call and tell them you need the 'Portage River Bridge raised Please" They control a few bridges in the area from a remote location. No need to re-call for them to lower , they will watch you clear from their cameras and lower when you all pass.. Just know you are at their mercy, that is a busy track system. calling over and over will piss them off, LOL..

Bridge in downtown normally has about a foot or more clearance than the RR bridge. It does raise at the top and bottom of every hour .

Not sure what type of boat you have , But if your a Lund ,Ranger,ect type boat you are clear sailing as far as bridges go.

My family and i has been in nugents for over 35 yrs and have seen it all as far as water level goes. Seen the canals almost dried up for a few years and have seen it over my dock by a few feet... Its has been pretty good the last few years due to getting some normal snowfall and rain here and the upper great lakes.

Enjoy your time here on our wonderful north shore!
