U.S. Army Corps of Engineers Pittsburgh District: Mark Novak hey Mark!
Here's a story we wrote recently about the hydropower plants at our various dams on the river and at reservoirs:
Todd Rygelski: When is this scheduled for demolition?
Michel Sauret: Todd Rygelski the schedule hasn't been set yet, but it's planned for sometime in 2024.
[The Braddock (#2) Dam is being made bigger so this one will no longer be needed.]

Joe McNeil: Let’s not forget totally decimating the fish population that lives there 🤦🏻♂️
U.S. Army Corps of Engineers Pittsburgh District: Joe McNeil I think you've missed the fact we just constructed 73 stone fish reefs in the Monongahela River.
Joe McNeil: U.S. Army Corps of Engineers Pittsburgh District I’ve read everything you guys have planned. But I think you’re missing the fact that the dam created the necessary levels of dissolved oxygen required during the summer for the insane amount of thriving fish there. That is their home and it’s about to be blown into oblivion. That river temp hits 85 degrees in the summer & feels like bath water. Those reefs will attract some fish of course, but it will never be even close to the same. Now people are just going to have to watch out for their lower units/props. Lol

| Mark Dodd commented on the above post I was the last of 5 generations of our family to live in the village of Lock Three, named after the original wooden locks. This is a picture of the original wooden lock and dam. |

| Jacob H. Ford Photography posted Here's another shot I took late morning from the Elizabeth Bridge, standing closer to the West Elizabeth side of the river from the bridge. Since my last shot with a towboat and barge was in black and white, I decided to keep this shot here in color. In this shot I captured a towboat and barges along Riverlift Industries in West Elizabeth, and another one farther up the river on the other side of Lock #3. What I love about this shot in addition to the fog on the river is the placement of the towboats and barges, while I intentionally included some of the cranes and other equipment for a more industrial look to this composition. The lowly fog in the valley also gives this shot an interesting look as well, with the thin layer of fog right over the water's surface giving the water an almost "silky" look. I may post a black and white version of this specific shot later this week, but for now, here's the color version. Enjoy! Photo taken: March 2, 2024 Jeff Warner: it's going to be wild to not have that lock and dam after July [2024]. [It looks like at least some coal is still being mined.] |

🚤 Hey everyone! Big changes are coming to the Monongahela River with the upcoming removal of the Elizabeth Locks and Dam.📅 Mark your calendars for the week of July 8, 2024, when the first demolition is scheduled to begin based on river conditions and weather.Expect some navigation delays as we work to improve our river!What to expect:- Lock closures for up to 12 days- Weekly navigation pauses- Safe passage through lock chambers for safe transitWe appreciate your patience with any navigation delays during this project. Please be extra cautious when navigating the river, and always follow posted safety markers and signs. Your safety is our top priority.Please help us spread the word to friends, family, and fellow boaters. Thanks!

| USACE, Pittsburgh District posted 🕰️ Historical Highlight: The Elizabeth Locks and Dam 🕰️ Built in 1907, the Elizabeth Locks and Dam has been a crucial part of the Monongahela River, supporting navigation and the community for over a century. It played a vital role in Pittsburgh's steel industry and served as a beloved community landmark. This historic structure not only facilitated commerce but also provided recreational opportunities for local residents, becoming a cherished part of the area’s social fabric. Families would gather along the riverbanks for fishing, boating, and picnicking, making memories that spanned generations. As we prepare for its removal starting the week of July 10, we reflect on its historical significance and look forward to a revitalized river ecosystem. Removing the dam will provide 30 miles of unobstructed river, benefiting aquatic life, commercial traffic, and recreational boaters. This project, part of the Lower Monongahela River Project, is expected to save $200 million annually in transportation and maintenance costs. Stay tuned for more updates!

| Facebook reel of blowing up the dam, Jul 13, 2024. 🚧💥 A Historic Goodbye 💥🚧 The lockmaster and three local residents marked a monumental moment at Monongahela River Locks and Dam 3 near Elizabeth, PA. Together, they plunged the handle of a blasting machine, signaling the end of an era! Since 1907, this dam has been a steadfast presence. However, the U.S. Army Corps of Engineers Pittsburgh District used explosives to breach the fixed-crest dam, kicking off its demolition and the eventual removal of the lock walls. 🌊 What’s Next? 🌊 The removal will create a seamless 30-mile stretch of riverway from Charleroi to Braddock, PA, dramatically improving navigation on the Lower Monongahela River. 💸 Big Benefits 💸 This is part of the Lower Monongahela River Project, expected to bring a whopping $200 million in economic benefits annually! That includes huge cost-time savings for transporting goods through the region and slashing maintenance costs. Watch this historic moment! [What are the white "tubes" in the screenshot?] |

Well, it finally happened!Strong winds and choppy waters caused long delays, but we successfully breached the fixed-crest dam last night at Monongahela River Locks and Dam 3 near Elizabeth, Pennsylvania.Notice: The lock will be closed to navigation for at least three days while the two pool levels equalize.Removing the dam will create a continuous pool of riverway stretching 30 miles from Charleroi to Braddock, Pennsylvania, improving navigation on the Lower Monongahela River.The dam’s removal work will continue through December. Until the Corps removes the entire dam and verifies the navigation channel is safe, all traffic must pass through the landside lock. After the initial demolition, contractors will perform additional demolitions once per week, requiring the locks to close for three hours or less.The demolition will require 13 more controlled explosions, taking down the rest of the dam in 50-foot sections. The contractor will use excavators on barges to remove the rubble from the river.After the dam is removed and the riverway is cleared, waterway users can navigate through the area without using the lock chambers. The river is anticipated to reopen by the end of 2024.The Pittsburgh District will then move onto the next phase of removing the lock walls in 2025, with work expected to last until 2027.The demolition is part of the Lower Monongahela River Project. Once complete, the project is expected to bring an economic benefit of $200 million annually, including cost-time savings in transporting commodities through the region using inland navigation and reduced maintenance costs.The Monongahela River Locks and Dam 3 has been operating since 1907, but the facility is prone to flooding and shuts down operations during high-water events, resulting in navigation delays.The U.S. Coast Guard supported by establishing a restriction zone 1,500 feet up and downstream of the dam.📷 by Michel Sauret & Stacey Wyzykowski

| USACE, Pittsburgh District posted We're accelerating progress on the Monongahela River! The Pittsburgh District is on track to open a 100-foot-wide navigation channel through the dam at Monongahela River Locks and Dam 3 near Elizabeth, PA by August 28 —months ahead of the original December 2024 timeline! After breaching the dam with controlled explosives on July 10, our team is working closely with contractors to restore a 9-foot draft, allowing commercial navigation without the need for the lock. This milestone is crucial for enhancing river transit and supporting our local economy. “We are committed to opening the 100-foot-wide channel through the dam for commercial navigations as safely and expeditiously as possible.” said Col. Nicholas Melin, commander of the Pittsburgh District. Following the channel opening, we'll begin demolishing the lock walls next year as part of the larger Lower Monongahela River Project—a $1.1 billion federal investment revitalizing one of the nation’s oldest inland navigation systems. These improvements will save commercial tows at least one hour of transit time, with expected annual benefits of $200 million to our economy. |

The U.S. Army Corps of Engineers Pittsburgh District is actively working to ensure safe navigation within the authorized federal channel on the Monongahela River following the removal of the Elizabeth Dam.Our contractors are conducting dredging operations from 6 a.m. to midnight each day to ensure the river remains navigable. This effort is focused on maintaining the crucial 9 ft. navigation depth to support commercial traffic.We are closely monitoring conditions and will continue to take necessary actions to restore full navigation capabilities for all river users.Learn more about our ongoing efforts here: https://www.lrd.usace.army.mil/.../lower-monongahela.../

You misworded
We made a massive mistake and rendered the river unusable now we are wasting millions of taxpayer dollars to have emergency contractors blindly dredging to try and cover up our mistake.
Ronald Towers: My question is are you also dredging the shore where the marinas are so their docs are not sitting on land anymore.
Chad Kalkowski: I wonder how many endangered fresh water mussels are now being impacted because of mistakes made.
