I got an email from Peter C. a few days ago (ok, over a week ago...) that I haven't gotten around to posting and sharing his photos and efforts. I have to say, this surprised me with how much he accomplished and how important it was.
There is, unfortunately, more in our drainages than just water. Typically we think of "drainages" as basins which have naturally formed to carry water down and away, eventually into either an ocean or the atmosphere. We have all seen that more "flows" through these basins than just water; I've seen countless tires, wheelbarrows, refrigerators, and other odd stuff.
To be fair, a lot of this is carried by flood waters (especially flash floods) as they tear through areas that aren't normally clear of debris; a lot of stuff is picked up and carried then. We can't always blame a "dumper," but this means we have to be even more diligent about cleanup efforts since floods can and do introduce some really awful stuff (and in large quantities) into the waterways. To That is almost certainly how this door came to be river-born.
A lot of paint is missing from that door, but look at how much is still there--Peter kept every bit of that paint from leaching into the water and tainting it with lead. Good work, Peter!!
