Rut head, I was down New Years weekend. I tried to see from the bank what they did above the dam and really couldn't tell much. I think all they did was dig out the holes that were normally there like was before the floods moved the gravel around.
It it looked like they were starting to build a pier out to the hole above the Holland dam. Some gravel built up about 12 ft out from the bank but that's it. The equipment was still there parked between the dam and the restrooms by the Holland dam on the field side. Long arm excavator, skid steer and tractor I think.
I thought I heard someone say they dug out from the dam back to the old wooden dam. Don't know.... I couldn't tell and I didn't fish there.
I fished from the spring down to the flats below the Holland dam to the bend. Fishing was pretty good for me. Others not so well. Midges and more midges. Plus a size 24 or 26 copper brassie thrown in the mix. Bounce em along the bottom.
