Weston Mill Dam Removal

[@jricans9974]

As a river restoration contractor myself, I am impressed with what you guys accomplished without a thumb on that Cat. That takes more skill than what most appreciate. Love to see what the rest of the country is up to. Keep up the good work!

Why would he need a thumb? It was a simple demo and excavation.

[@jricans9974]

You're the guy I was talking about who doesn't appreciate it.

[@MassacrePoon]

I felt bad for the hammer though

[@NFSGamerful]

It's weird to me seeing thumbs being used on excavators. Over in western Europe we tend to use very different stuff. The hammers are actually a rarity to see, it's all hydrolic shears here which tend to just be a lot more flexible. If you're curious google Verachtert equipment and you could see some examples.

[@ThePixel1983]

Yeah, I guess it takes quite some training to "become one" with this equipment. That timer could have easily fallen off the shovel, for example.

March 13, 2019---Thanks for the video. It's strange (at least to me) that this was a technical marvel back in the 1800's and helped build America, but has now outlived its usefulness. With all these dams removed, wonder if the fishing quality improved.

[@JohnWJengo]

It had out-lived its usefulness, but you are absolutely correct. The history of this country would have been poorer if not for water-powered milling. And yes, the fishing has greatly improved and we are seeing migratory fish upstream of this former dam structure for the first time since the mid-1700's. Thank you for your comment.

[@nickbeam5432]

John , i have a question , is that a bridge i see behind the dam ? and if it is, was it built after or before the dam ? The only reason i ask is the difference of pressure pushing or holding against the earth when it comes to the ground shifting do to weight, i just wondered if removal would cause any unstable ground shifting around the bridge structure, and if so why they didn't concrete cut paths threw the weir for the fish.

[@JohnWJengo]

Nick, this is such an excellent question. By my reckoning, that bridge may be the 4th or 5th bridge at that location, and luckily when it was rebuilt in 1995, instead of having the bridge abutments/piers rest on the gravelly stream bed like the former bridges, they dug down and anchored the abutments/piers deep into bedrock. Our scour analyses (required by our Dam Safety removal permit) indicated that the removal would not affect those anchored piers (but it would have if those piers were resting on the stream bed). I hope this answers your superb and insightful question. Thanks.

[@ScottWiecenski]

I grew up a few blocks from this dam and have fished the Millstone my whole life. As a kid I was there fishing early in the morning right by that dam when I heard a creaking sound, then a snapping sound, then the whole mill collapsed and fell into the river. I watched it happen. This was back in the early 80s. I still fish there, and I hope the Northern pike come back. I've never caught one, and I'd love a good fight with one.

[@JohnWJengo]

Wow, that is amazing that you were there. I wish I could have prevented that catastrophe from happening. The more I learn about Weston Mill (which I'll be posting a video about fairly soon), the more I wish it was still here for us to appreciate. Thanks.

[@guyparris4871]

[@JohnWJengo]

I am so pleased to report that staff from the NJDEP’s Division of Fish and Wildlife and the U.S. Fish and Wildlife Service found evidence of successful American Shad spawning in the Millstone River following my August 2017 removal of the Weston Mill Dam. Five juvenile shad averaging 4.3 inches in length were found 4.5 miles upstream of the former dam. I am convinced that this is the highest upriver occurrence of shad since the original construction of the Weston Mill Dam in the late 1740's, and it's such wonderful news. For more information about the types of fish now re-populating the Millstone River, please see: www.njfishandwildlife.com/artmillstone.htm?

[@michaelbyrne8860]

Wow very cool! Loved to see those old wood cribbing timber of 1844 to use to make something? I bet that old growth wood grain would be impressive after a stain was applied?

[@MrAndrewFarrow]

If the fish had been prevented from swimming up river for 275 years did they then suddenly resume doing it?

[@JohnWJengo]

In a manner of speaking, yes. Unlike salmon, a certain percentage of our species of anadromous (migratory) fish (American shad, river herring) will choose a different river than their hatching river to return to in order to spawn. So, when an obstacle like Weston Mill Dam is removed, there are indeed fish that arrive the next spring to migrate upriver to spawn, which is exactly what happened the year after this dam was removed. This is a species-specific characteristic that has really helped shad and herring re-populate rivers that have long been blocked by dams and other obstructions. Thanks for your question.

[@lkmayhew9390]

Really nice job by the backhoe operator.👌

All praise to the men who removed the concrete and junk so that the river might run free again....

[@lurchie]

I bet that sediment is some fertile soil.

[@JohnWJengo]

Interesting that you would say that. The operators of the Island Farm Weir downstream occasionally dredge sediment to keep their intake pipes clear and they do send the material off to be bagged up and sold as top soil at a local garden center. Thanks for your comment.

Beautiful cleanup, that river will be quite a lot better off for it. I'm all in favor of hydropower dams and usage of natural resources like this for renewable energy, but when something has become outdated and disrepaired like this, it's time to remove it again and clear the river. Hoorah better fishing! I'm surprised there was no thumb fitted to the excavator used! That operator is darn good.

[@ankles632]

[@busslayer4790]

How long did this job actually take?

[@JohnWJengo]

The actual time in the field demolishing the dam, including several weather delays when the river flooded after a rain event, and mobilizing/demobilizing the equipment from the site, was two weeks. Actual time in the river, if I excluded these delays and other housekeeping that we needed to do, was about 5 days. Thanks for your question.

[@Rhynri]

The bit with the kayak running the gap is a crucially important part of the process and should not be overlooked. ;)

[@Kreedogger]

[@808hawelu]

I’m wondering why none of the equipment that’s inside the water had a spill prevention kits on them. And I don’t seem to see any sediment retention ponds or anyway to separate the concrete sediment into the following creek I thought the whole point of this project was to restore the natural habitat

[@fetsluck5620]

They may have had it father down. One bc of the articulation truck having to cross back over to the other side. I have been environmentally hazardous trained site worker. And I did see a couple things that were not noticed. But I would say that they did have the retention damn down stream just out of camara view. Or I'd hope they did anyway. I'm sure the EPA was there for the whole thing. If not then wow they justed posted a big fuck up. Bc theirs way more to this than just tearing a damn out for better fish population. Good eye though. Sounds like you too have some background on this kind of stuff. I had to take a 40 hr class in Indiana for my certification. It was definitely not a easy thing to get and it's been well worth it.

[@fetsluck5620]

Keoni hawelu idk how to get it to tag you in this so it gives you a notification so hopefully you will see this. If you know how I can get it to tag like turn your name blue. Let me know bc I've done it once or twice bit I dont remember how lol.

[@JohnWJengo]

I mentioned this under another comment that although not a requirement of our removal permit, we swapped out the usual hydraulic oils of the excavator with biodegradable, non-toxic oils in case we had a leak, which thankfully did not occur. The integrity of the hydraulics of the truck were checked before each foray into the river. Our engineering evaluation determined that there would be a de minimis release of concrete that would not affect the downstream environment (and the Bureau of Dam Safety that issued our removal permit agreed, as did the Division of Land Use) and the entrained material would be part of the approved sediment release that was needed to restore sediment-starved embankments just downstream. There are instances where sediment has to be captured (or removed ahead of time if it is contaminated) before a dam removal but those conditions did not apply to this removal. Thanks for your comment.

[@fetsluck5620]

@@JohnWJengo thanks for that info. I'm not a damn expert lol. But that makes sense. I didn't think about the embankment downstream. And I did forget about the environmental hydraulic oil. Haha I tell ya theirs alot in that book for hazardous materials handler class I took and it's hard to remember all of it. But like I said I'm no damn expert either lol. But I was surprised that their wasn't not floating oil pads or booms down a little ways just as a back up for the articulating truck. The way I understood it was that the trac hoe had the evo hydro in it but the truck didn't, it was just inspected every trip bf entering the water. Correct? And I'm glad yall didn't have any leaks at all either bc that could have been a hell of a costly job then. I've had to clean up diesel out of a creek before and man it wasn't fun even with the floating skimmer hooked up to my vac truck. You go pushing and pulling a 3 inch hose with that skimmer on it and you get tired really quick and with the epa breathing down your back it's no fun. All though not all the epa people are asses but most of them are. Yeah they are doing their job but man they can be some picky picky people. Did they make yall take water samples bf and middle and after? Just wondering bc I get into this kinda stuff. And the hole damn removal is something new to me. It's not like pulling the steal fuel tanks out of the ground and putting fiberglass ones back in or just filling the hole back up and then ever so often go and check the groundwater and make sure theirs no more fuel in the ground that may have seeped out even though dirt samples are taken bf. Can't wait to hear back from you. Thanks for all the info. O and one more thing I noticed you never said anything about the epa just the DLU and BDS. Was the epa even their or make a presence known? I kinda figured they would have showed up bc of the equipment in the water. Just wondering. Thanks

[@JohnWJengo]

@@fetsluck5620 Yes, that's right; the oil pan of the articulated truck was inspected prior to each trip in the water. It just wasn't feasible to boom off the river downstream, especially with the current restored once the dam was breached. And the USEPA had no involvement in this project; they are not involved in projects in New Jersey that are not in the Superfund investigative/remediation program or don't have PCB issues (those are the only areas where their jurisdiction overrides the New Jersey Dpt of Env. Protection [NJDEP]) - all the work was governed by the five different permits issued by the NJDEP and their ancillary agencies. I did have a kit to sample surface water if we had a leak, but as you noted, we had no problems so I didn't need to use it. Thanks for your comments.

Excellent question! The mounded sediment from behind the dam was used to fill in scour holes caused by the dam just downstream and re-build the shoreline back to the way it was originally. All of the concrete was taken to a concrete recycler (and I heard some of it was re-used as roadway foundation material), the few pieces of steel were recycled also at a local metal recycling facility, and lastly, some of the timber crib wood was given to historical organizations, some was re-purposed by wood turners into bowls (they liked the black color of the wood) and the rest was left by the mill ruins for historical context.

Very good question. Because this was a run-of-the-river dam, it had no flood storage capacity.

[@miketoothacker8124]

The dam was out of service. Why dam a river if u don’t need to?

[@eddjordan2399]

great job. nice to see humans being good to nature.

Should've got 617 squadron to do it.

[@MrAndrewFarrow]

Doesn’t it cause an initial flood downstream? Who’s responsible for any downstream flooding?

[@Harry_Gurvich]

the Raritan River is immediately downstream of this site. it is significantly larger than the Millstone River (capacity) and I would think easily capable of handling the temporary increased flow

[@JohnWJengo]

This is a really good question. I had to schedule the breaching of the dam on a particular day and at a certain river flow when the "excess water" would not cause flooding downstream; the minor rise in water level over a 24-hour period was acceptable because I picked a day when the normal stage of the river was lower than average. Thanks for your comment.

Loved it!!! Those guys worked their asses off!! Good job!

[@michaelbagley9116]

Industrialists are interested in building, using, and not removing their work. Unfortunately, it becomes the later generations that have to clean up their mess as it becomes a public hazard. We need to start making these industrialists of today pay into a fund to remove their messes as they start their projects. Figure it into the costs.

[@Golden-dog88]

so you wana force people to pay for something that everyone agreed upon just incase 1 day in 100+ years someone else might winge about something they build and want it removed????? YOU START THE FUND AND ADD THE FIRST 20,000,000

[@peanut1001x]

golden-dog yes that's exactly what we want & if no longer owned local council that benefitted from all the taxes can pay. noone supports your outdated obsolete views so go away.

Two Interesting facts about the Weston Mill Dam: 1. It was built in 1935 2. You didnt search for this video...

[@ScottWiecenski]

Yes, I did!! I grew up a couple blocks from this dam.

[@JohnWJengo]

Thanks for your comment. In my continued research on the dam itself, I am certain now that the concrete dam that was capping the older dam structures was built in circa 1948. It is true that a 1935 date is often quoted as the date the concrete dam was built based on two newspaper articles from that year [The Newark News (September 30, 1935) and The Sunday Times (October 6, 1935)] and indeed Wilbur Smith (who owned the property between 1925 and his passing in 1984) reinforced the timber crib dam that year with steel sheets purchased from junkyards, 16-inch beams, and galvanized bolts. But by cross-checking these 1935 articles with other newspaper accounts and interviews with Wilbur Smith in subsequent years, Wilbur stated that he rebuilt the dam using concrete some 13 years after trying to repair it with steel sheets, which would place the concrete dam construction date in circa 1948. Thanks for your interest in this project.

[@adambrown865]

Great work to all concerned.

[@takumi2023]

Not an engineer but can anyone tell me why they didn't just break the dam into two section and remove each section one at a time? It would prevented a lot of sedimentation from flooding down all at once. Ture those are the sediment that should have gone down stream but not all at once also because of the time of year the velocity of the river is different from when it normally erodes/carry sediment.

[@JohnWJengo]

That is a really good question. Our NJDEP Dam Safety permit required that the entire dam be removed at one time so as to not leave a potential flood hazard in place. In terms of the sediment, we were given a time period where that sediment could be released downstream without the risk of harming fish populations (i.e., after the spawning and migration season and before the young-of-the-year would be heading downstream). Thanks for your question and interest.

Just put a generator in it and it stil can provide some electricity better than those stupid solar panels or wind mills

[@karenburrows9184]

JIJzer: A generator. Really. There hasn't been a need to generate power on that river for some time now. BTW, what have you got against solar panels and windmills?? Lots of houses and properties running on those these days. Without damaging rivers and killing fish.

[@jijzer3284]

@@karenburrows9184 seriously you believe that solar and windmills are delivering power. Only 2% of the energy is coming from that and that is when they work 50% of the time they are doing nothing no wind no sun. Those windmills and solar panels are a big lie.

[@jijzer3284]

@@karenburrows9184 and windmills are killing more birds then dams kill fish

[@karenburrows9184]

@@jijzer3284 Your comment led me to check the recent data (I didn't have the exact figures) and I found: in 2017, the Smithsonian showed scientific studies proving that 328,000 birds per year killed by wind turbines, 100,000 birds killed by cats annually (bonus fact). Contrarily, 100,000 fish PER DAY were killed by dams; and in 2017, a Fisheries study showed 250,000 to 400,000 salmon (alone) were lost to dams. It was also proven that fossil fuels are more deadly to birds that wind turbines. I don't know if this is of use to you.

[@karenburrows9184]

@@jijzer3284 Man, you're making me work. Yes, they are delivering power. Overall power from renewable sources: China: 14%, India 11%, the U.S. 8%, and here in Canada, 17.3%. 3% of that is from solar; doesn't sound like much, but that's 2.5GW = 1 million homes. In a country with some serious daylight-in-winter issues. There must be something behind it, the market's growing. No, I personally do not have either.
