At the moment there is a move to either repair, or remove the head of the tide dam in Durham. A friend of mine is trying to steer the decision towards removal.Does anyone have any interest in helping out, or any experience with successful removals? If so send me a PM, or reply on here. Monetarily it makes sense to remove, but for anyone who knows Durham there is going to be push back from residents about the potential change. Environmentally it would be a big win, and as luck would have it removal will be far less expensive then repair.
didn't they do something similar in Exeter..it would be nice for the environmental point of view..
It comes down to money. Newmarket ponied up $2M to repair the Macallen Dam. Focal point for business. Winnicut river dam came down 13 years ago. No studies to prove if it helped environmentally.
Huh? The dam is a focal point for business? The Newmarket dam was a joke, it costed way more to repair then remove, there was even an existing ledge under the dam and it would not have reduced the levels as much as people think. Some old lady came down to one of the meetings and said “this isn’t the Newmarket I want to know” (without the dam), and everyone’s brains melted. My friend who lives in town and pays taxes still boils over it because the repair had something like a 6-60 year warranty on the work done, lol. And it was like 600k to remove I think?If it came down to money none of these foolish dams, which provide zero economic value, would be repaired because it’s cheaper to remove in most scenarios locally. These are old defunct dams that now serve no functional purpose other then to continue to hurt the Great Bay ecosystem.And the winnicut dam “removal” was a joke. It’s a ALS dam, which only shad and ALS can pass (you see these in some of the remaining ALS waters up north). It’s useless for the salter trout, alewives, smelt, etc except in the most ideal conditions.
I think I have had a bit too much too drink to respond tonight,
Or maybe take some of the money saved from removal vs repair and out it towards nutrient mitigation or improvement of waste treatemrny facilities?
I don't know how Mill Pond is fed, but it doesn't seem to have headwaters to support restoration of anadromous species (same situation as previously mentioned in an earlier post with the Winnicut dam). I may be wrong.
It's the Oyster River and you are very wrong. When I was at UNH back in the 80s, there were so many alewives in the upper river you would walk across on their backs. Not saying the run is as strong now but removing the dam would certainly help.
Actually the runs are at historic lows. I may have them confused but the blueback herring run on The oyster was the biggest historically, and the last few surveyed have showed drastically decreasing numbers.
I don't understand what you mean by upper river. The Oyster River, above the dam, is nothing but a tricking brook like the Winnicut that was mentioned in an earlier post. Dam aside, have you tried to take a boat up the Oyster river at low tide up to the dam? Good luck. Dinged props in the channel while the motor was trimmed - no water. Appreciate the dialogue.....
