When I was a kid, I screamed if I saw a snake in water, as I was taught all water snakes were water moccasins or copperheads or cottonmouths. But, I have learned that MOST water snakes in IL are not poisonous, and although this snake, both the first time I saw it and this last time, sure did give me the impression it was poisonous because of the triangular head, I was thankful I got really good close up pics the first time of it's eyes, and learned it was not. Snakes have lots of ways to make themselves seem deadly to other predators, and making their head go into a triangular shape must be one for them to use on us humans. LOL
I know this is gross, and I should have buried it, but instead I dropped it into my trash container that is for my month worth of trash, so it's about 4' deep, and wider than that. Anyhow, it stunk terrible for a week, and finally I peered in there and saw maggots covering one area, so I knew they would do their thing. About a week later I got the guts to look again, and there was a shadow of maggots where the snake HAD been! It was totally gone, bones and all, poof, GONE! Maybe there are not bones, come to think of it, but anyhow, it was totally gone, no smell anymore either.
The first time I tackled this snake, I was petrified of the whole situation, but HAD to get it out of my pond, or I would have been scared to death to go in there to groom my lilies! I was on a mission, and I was not going to miss my opportunity. If it had gotten out of the skimmer, no way would I have been able to capture it with any ease, so I knew I had one chance, and got lucky. But, when I opened the top of the skimmer and was going to poke at him/her to get it to go into the net I had covering the opening, I had no idea the skimmer box would be FILLED with snake! That sucker didn't look nearly as large by seeing the head as it was by seeing the body. It was heavy to carry in my net, too. This time around, it was larger, but I still believe it was the same snake, coming back for more easy meals.
