1915 NYC Ashokan Reservoir & Arch Bridge on Esopus Creek and 92-mile (148km) Catskill Aqueduct

Reservoir: (Satellite)
Bridge: (Satellite)
Browns Station Fountain: (Satellite)

This reservoir was built by flooding a bowl in the mountains rather than building a big dam. This is the levee that has the spillway.

This contour map shows the two basins that were filled with water.
I'm glad I found this map because, even though construction didn't start until 1907 [TripAdvisor], some 1901 and 1903 topo maps already show the reservoir.
DEC_map

I did find this topo map that correctly shows the land before it was flooded. Note that the Ulster & Delaware Railroad used to go through the valley.

"Ashokan Reservoir, located 14 miles west of the City of Kingston in Ulster County, was created in 1915 by the construction of 5 ½ miles of dams and dikes within the Esopus Creek drainage. This 8,315 acre reservoir is a major component of the Catskill System of the New York City Water supply. The reservoir is broken into two basins by a dividing weir near its center. The Dividing Weir, pinches and separates the upper west basin from the lower east basin." [DEC_reservoir]

"The Ashokan Reservoir was built between 1907 and 1915 to supply water to New York City. The flooding of twelve communities and thousands of acres of farmland sparked long-lasting controversy. The last of the land claims were settled in 1940. Two thousand residents were moved, some of the communities were relocated, others were flooded."

Arch Bridge


I was confused by phrase "a dividing weir near its center" in the above quote because I found a bridge instead of a weir. I guess there are concrete barriers under each arch.

Yep, this view better shows those concrete barriers.

And this view shows another levee to form the reservoir.

"The Esopus Creek enters the Ashokan’s West Basin and after a period of settling flows over a weir or is released into the East Basin. From the East Basin, water is released into the Catskill Aqueduct for drinking water use, or discharged via a release channel into the lower Esopus Creek." [AshokanStreams]

Sometimes, the eastern basin is significantly lower than the western basin. And we can clearly see that the bridge is over a dam.

The current fountain replaced the original fountain that was built to aerate the water to remove odors caused by the plant life and soils in the flooded basins. The fountain replacement happened when hydropower was added to the project, and the fountain runs only when the turbines are turning.

This is what the original aeration fountain looked like.

Catskill Aqueduct


This reservoir is part of the Catskill Water Supply System.
This system supplies 40% of New York City's daily drinking water needs in non-drought periods. [NYC_reservoir]

The remnants of the wooden dam is in the foreground.
Rusty Heyn, Jul 2021
"The Redridge Steel Dam, located near the far, northern tip of Michigan, is the largest, surviving representative of this exclusive engineering."

Above is the upstream face of the steel dam. The reservoir has been drained. That is why we see the wood-crib dam. Below is the downstream face of the steel dam.

The water is maybe 6 feet below the bridge currently. 
Crazy amounts of much needed water coming down today 🙏🏽
All praise to the most high!
Robin MacDonald: Where exactly is this on the Salt River?
Rico Loroña: Above Roosevelt lake
Dennis DeBruler: It appears to be this bridge: https://maps.app.goo.gl/v8239ceZBTfPuYT58

This is a Salt River take-out ramp. One would not want to be parked there on Nov 1, 2026.

Diversion Dam


The water is diverted into a tunnel. I wonder where that tunnel delivers the water.

Sally Rector commented on the above Facebook Reel
I was right there about 6 weeks ago…Here is the spillway just downstream…

I assume there is just one diversion dam on the Salt River.

🌊 The Salt River at Diversion Dam is an incredible sight right now!
Currently flowing at a reported 95,000 cubic feet per second (CFS), the Salt River is moving an unbelievable amount of water. That’s over 665,000 gallons rushing downstream every second!
Large debris can be seen floating downriver, showing just how powerful the current really is. The familiar steps at Diversion Dam are nearly unrecognizable, with only a small tide-like ripple visible where rushing rapids now cover them.
I’ve seen the Salt River flow plenty of times, but this is by far the highest I’ve ever witnessed it.
It’s an amazing display of Mother Nature’s power, but also a reminder of just how dangerous these waters can be. Respect the river and keep your distance! 🌊

1921-2019 Dicks Road (CR 500 East) Bridge over Clear Creek uses bolts

(Archived Bridge Hunter; Bridge Hunter; Historic Bridges; B&T; Satellite)

"This bridge is an extremely early example of a truss bridge with bolted connections. Bolted connections only became popular in the second half of the 20th Century, as riveting lost favor as the preferred bridge fastener type. This bridge retains good historic integrity. It has been supplemented with post-tensioning cables, but these do not diminish the original material or design." [HistoricBridges]

Bridges & Tunnels by Sherman Cahal posted four photos with the comment:
The Dicks Road Bridge has spanned Clear Creek in Putnam County, Indiana, since 1915 [Both BirdgeHunter and HistoricBridges specify 1921.]. What makes it unusual is how it was put together: bolted connections were uncommon in Indiana trusses this early, and the floor beams are bolted to gussets below the lower chord rather than riveted in place.
The bridge was closed in 2019 after it failed an inspection.
🧭 More photographs and the full history are available through the link. A visit helps support Bridges & Tunnels's ongoing work documenting these places through research, photography, and preservation-focused storytelling.

Grays Ferry Bridges over Schuylkill River in Philadelphia, PA

2027 Trail Swing Bridge


HiddenCityPhila
In 2017, ownership of the bridge was transferred from the railroad to the city so that an operating swing bridge with more clearance could be built for trail use. The railroad bridge was torn down in 2018, with completion of the $13m project projected for 2019.

The actual completion was in 2027, and it cost $15m.
Facebook Reel
Philadelphia is about to open a brand-new $15 million pedestrian bridge — and it actually rotates to let boats pass.
It's called the Schuylkill Crossing, connecting Grays Ferry Crescent to Bartram's Garden using restored piers from a 1902 railroad bridge. It officially opens Friday, November 13th.
So how does it actually rotate?
When a boat approaches, safety gates close and an operator pivots the 226-foot span horizontally. The process takes about 3 minutes, and during construction, engineers said the 60,000 pounds of steel at the pivot was so balanced you could push it by hand.
Here's why this matters locally.
Before this, trail users had to ride alongside 4 lanes of traffic on the Grays Ferry Avenue Bridge. Now, it creates a direct, car-free route connecting 4.7 miles of continuous trail into Center City.
There's an opening ceremony Friday, November 13th, and a community celebration Saturday, November 14th.

Demolition started in 2018 as planned.

Construction did not start until after Apr 2024. I have not been able to determine why it was delayed so much. Covid-19 should not impact it that much.
Street View, Aug 2025

Before Nov 13, 2026, trail users had to share the road bridge. At least they added a barrier between the traffic and the sidewalk.

FishPasses on Boardman River in Traverse City, MI

Boardman Weir: (Satellite)
FishPass/Union Street Dam: (Satellite)

When you search Google Maps for "fishpass," you get Boardman Weir. But the following dam is upstream of Union Street and is the FishPass.
FishPass posted six photos with the comment:
Breaking News: Logs are off the arc labyrinth weir!
During April’s big flood, large debris was carried downstream and snagged on FishPass. -Special thanks to Team Elmers for finding a safe, effective strategy to clear it.
(A heavy duty floating debris boom will be placed upstream to catch future floating hazards before they reach FishPass.)

The keyword in the official title is "harvest." Most of the salmon is sold. [michigan]
The City of Traverse City posted four photos with the comment:
It's that time of year! [Oct 4] The Fish Weir on the Boardman/Ottaway River in Downtown Traverse City plays a crucial role during the salmon run, particularly in the fall when Chinook and Coho salmon return from Lake Michigan to spawn. The weir, which operates generally from mid-September through October, is set up to capture these fish, preventing them from traveling further upstream. This allows the Michigan Department of Natural Resources (DNR) to better manage the fish population.
Check it out! It's a sight to see!
Kyle Becker: Better management would be letting them pass thru the new Fish Pass when it's done. Eliminate the meat take, to only spawners that may die during egg and fluid harvest.

2025 FishPass (labyrinth weir and sorting channel) and 1987 Union Street Dam Fish Ladder


"FishPass is the capstone of a ~20y restoration project on the Boardman (Ottaway) River, Traverse City, Michigan re-connecting the river with Lake Michigan. FishPass will replace the deteriorating Union Street Dam with a new, complete barrier to all fish that will have the ability to sort and selectively pass desirable fishes while blocking harmful invaders like sea lamprey. While fully automated selective passage is the long-term goal of the project, passage of any fish during the initial 10-yrs will be coordinated with fishery management agencies, limited in number, and restricted to fishes native to the upper Great Lakes." [glfc_fishpass]

FishPass has a long sorting channel.
