UINR wishes to inform the public to exercise caution
when using the Middle River for recreational boating purposes between April 16 and June 30, 2012.
UINR will be installing a Rotary Screw Trap (smolt wheel) on Middle River at approximately 46° 05’ 49.8N, 60° 55’ 18.8W to catch Atlantic salmon smolts to estimate their abundance and monitor fish populations.
This wheel is noticeable by warning signs and safety markers. Boaters are advised to watch for this device when setting out on the river, especially at night or during conditions that reduce visibility.
