Out in Portland Oregon the drains are unusually hard to get into. Using some interesting old maps we have managed to find a very interesting looking one, but the only manhole to it is buried. This should be fun, the game is on.
Until more news on that here are a few pictures from one of portland's few easy to access drains: The Lower Macleay Park Inlet
This is leading up to the infall:
the stream is crossed by a number of rickety old wooden pathways. Suspended below them are wire screens stopping debris from entering the drain.
Next comes the actual inlet structure. This structure is so awesome, that I am going to leave it a secret for now. You will just have to check it out to see it for yourself. Once you get past the infall structure a pleasingly oval RCP greets you:
Just inside looking out:
Looking down:
The drain is full of amazing artwork, some of which is quite good. Some of which is very educational, like a timelined hall of great scientists. And some of which is quite silly like the famous (or infamous) hall of cocks.
The drain itself is rather long and boring until it almost reaches the river. At that point it is joined in a confluence with another large drain. Perhaps more pictures to come later.
Hope you enjoyed.
