Subject: Princeton Dam Update


Following a recent pre-construction meeting, more details about the Princeton Dam project have been announced. I wanted to provide you all with a quick update.

  • The state contact of this project has an end date of November 29, 2020.
  • Following mobilization during the week of October 14, 2019 they intend to install a coffer dam on the north end of the dam.  This will allow them to install the new fish passage and phase one of the weir cap and downstream rip rap – This effort and how far they get is entirely dependent on the weather but they intend to work as long as conditions allow.  With the onset of winter conditions, they will secure the site, remove the coffer dam, any excess materials, and equipment and mobilize off-site.
  • Once river conditions allow, typically after May on the Fox River, they will return to complete the project including the remainder of the weir & rip rap installation, replacing the lock channel gates, and reinstalling the upstream cable restraint.
  • Construction activities require a significant portion of the site to be closed to the public.  Property staff will address this task through the Fisheries program. The public will not be able to utilize the majority of the North shore of the public fishing area or the upstream (west) boat landing.  They will continue to have access to the downstream boat landing (east), the entire south shore of the Fox River and a portion of the North shore.

I will continue to provide you with updates as I receive them. If you have any questions in the meantime, please feel free to reply to this email.
