Fish Camera

Welcome to the 2025 Town Brook River Herring Migration!

The live feed this year has been very poor due to wifi connection issues, so we've been losing about 95% of our frames. Please check www.plymouthriverherring.org for video clips.

This feed shows the annual herring migration up Town Brook in downtown Plymouth in real time! Thanks to a multiagency collaboration with NOAA, Massachusetts DMF, Plimoth Patuxet, and the Mystic River Watershed Association we're excited to have installed this system to assist with data collection and provide this unique view of the run. Every fish that migrates up Town Brook has to swim by this camera, so we're hopeful we'll see a good number of fish come by this year! 

We crowd source our herring counts across the globe to help us collect data. To help us count river herring visit our website plymouthriverherring.org!

Fish will be swimming upstream (from left to right), against the current. You may notice debris, leaves, vegetation and other objects washing downstream (from right to left) on occasion, or circulating through the system. But when you see a fish, you'll know it! Individual fish are different, so some might zoom through quickly, others might linger a little in front of the camera, and some might even drop back downstream, but it's all normal. You might even be lucky enough to see a bass come in from the right and try to nab itself some lunch!

Natural Resources personnel visit the camera daily to clean it; this may include cleaning the counting boards, removing debris, adjusting and cleaning the camera, etc. You'll notice the water clarity increases and decreases based on weather and light availability. Poor visibility due to recent rains typically clears up in a couple hours, and maintenance may similarly cause poor conditions for a few minutes. If the feed freezes, try refreshing the webpage.

We're extremely excited to have it up and running, and hope you enjoy watching the migration!
