| Status | injured |
| Type of Debris | mono-filament fishing line |
| Comments | line gets wrapped around the claw somehow and they can't free themselves. many were already dead. I typically try to cut the line but some are hopeless, so it's easier to remove a claw. I try to leave at least one intact. |
Additional Information
blasting cap
fish entrails - diminished crayfish population insufficient to consume, and increased bacteria is altering the system
increased amount of mono-filament - it doesn't degrade
Comments and Feedback
This is was our 40th annual cleanup under this dam. We've seen the water clarity diminish over time (25ft to 10 feet), and the crayfish population crash. I wish we were taking actual counts over the years, since this is just a casual observation. Where we used to see 4 or five, we now see none to 1.
