Car Dyke, northern end | River Welland, east of Lincoln, UK | photo PHEW | circa 130 AD | Engineering Timelines | associated engineer
Originally thought to be a navigable waterway and now thought to be a Roman catchment drain, Car Dyke runs from Lincoln to Peterborough along the foot of the Lincolnshire Wolds.
If the suggestion of Roman construction is correct, then Car Dyke may be thought of as the first large scale effort to improve the Fenland. As the Fens are relatively flat, it was quite an achievement to keep a constant gradient for water flow and arrange continual fall from each upland catchment area as it passes by.
The dyke has silted up somewhat since Roman times and has been recut in various places. We do not know its original dimensions but near Lincoln it may of been some 45ft wide and 13ft deep. The picture was taken in 1978 at Potterhanworth Booths.
The southern end is at OS grid reference TL200980.

“WOW”
I’m with you. The ability of them to build aquaducts for hundreds of miles, or even this dyke for 70 miles is amazing, considering they have to get the slope just right (i.e., too little and the water pools or spills over, too much and they quickly run out of vertical drop to use. And then the weight and subsidence issues - WOW!. And this is based on my experience in trying to lay 100 feet of 4” PVC drain line...not as easy as it looks.

What perplexes me is that these earthen structures have not fallen into invisibility through erosion and become mere depressions that are hardly recognizable as man-made.
The other factor is being able to run a line of levels this far across terrain and get the right slope to encourage adequate flow without over flowing.

I'm reminded of the 176 mile long

Parts of the original canal silted up. About 300-350 years ago there was a need to build a canal system in England to drain off standing water and open up more land for agriculture, which also transitioned into the pre-rail heavy cargo transit.

It’s longer than Hadrian’s Wall, and wasn’t built by Offa. :^)

They had a lot of experience with water handling in the form of gravity-fed (rather than pressure-fed) aqueducts and inground sewer systems that didn’t clog.

Heh. Mercia built a wall to protect its border. ‘Merica should do likewise.
