    While its hard for me to get the time to go out and fish due to new parent obligations , I found some spare time to fish. I decided to go to Evans pond, one of San Diego's local ponds. Sadly I came to a fish die off. Some theorizes that the pond is poison to keep the smell, and or population of anglers down. while others theorizes that due to increased temperatures and lack of water, the oxygen levels depleted. In past times, I see this pond have gone through multiple fish die offs :emoji_disappointed_relieved:

    While all my other videos are more upbeat and positive. I really wanted to share this with you guys and ask the question . What do you think killed the fish?

    I was there the day before and it seemed fine. Small bass swimming near the shoreline, koi, and turtles swimming about trying to bite my topwater frog lure. The next day I wanted to try out my new Shimano slx xt, and all I saw was death, a few other anglers were there questioning and speculating what had happened. Just like you, some said weather or lack of oxygen due to an algae bloom, but the aerators were all on. I don't think I'll be going there for a while.

    Is it possible that the aerators didn’t produce enough oxygen for the fish? There’s like 5 of them across the pond so is that enough aeration for fish to survive during an algal bloom? Or did somebody seriously poison the fish? I would really hope not but how else can the die off be explained if there was enough oxygen in the pond. What do you guys think??

    4-5 aerators in a pond that size is BEYOND sufficient. O2 has zero to do with the die off on my opinion. The guy that you got audio of nailed it. I think enough locals/residents/whatever complained and whoever the administration of that pond was tool drastic measures. The worst part is, you will most likely get no solid information as to exactly why or IF any chemicals were introduced to reduce the smell. There may be some potential algae/bacteria threat, but thats a stretch as to why a pond of that size would be treated "allegedly" with harsh enough chems to create a die off of that size.

    My hearts out to you Rodmaster858, I would be super bummed too. The look on your face kind of said it all at the end of the video.

    Yeah, I was there Thursday morning, and all was fine. Fri morning, mostly all dead/dying, except the orange koi. At least I got to say goodbye up close, if he didn't make it.

    I'm leaning towards O2 depletion. I've only seen 2 aerators running, and this pond has had die offs before. If it was poisoned, I would think you would need A LOT of poison, something that would have to be regulated. I doubt some rogue person would have the means to do it at that scale.

    This was brought up in another thread, and also on the news, and most others lean towards O2 depletion.

    Harmful algal bloom is not always mitigated by aeration..

    Thanks for the concern, yeah I was pretty bummed out. I took my daughter alana, here handful of times, to unwind and have her enjoy the outdoors. but now , it will have to be another place. im hopeful that this pond will recover. As I heard, in recent times, that this pond has gone through fish die offs before.

    tight lines!

    Sadly enough, a common thing for that pond, and a few reservoirs I fish in the IV too...

    I took my grandaughters there the other day for the first time and while it looked "fishy" it was a waste of time. What a shame as there are few places in SD where little kids can get started fishing like we all did with the basic worm/bobber rigs catching panfish.

    Smaller bodies of water are highly susceptible to temperature swings.

    Here’s an excerpt about a much larger body of water that experiences this same condition during the summer and Santa Ana months:

    “Biologists say that fish die-offs--which occur when rising water temperatures promote the growth of algae that rob fish of oxygen--are a natural phenomenon at many of Southern California’s inland lakes.”

    Try Libby Lake in Oceanside. I haven’t seen it recently but it was a lot like Evans pond. I fished Evans as a kid but two of my boys caught their first at Libby. It’s a drive but might be a bandaid until Evans recovers.....

    If anyone has any recent intel about Libby Lake it would be appreciated.

    Does anyone know what's the deal with Poway Pond off Pomerado? I see reviews online, suggesting it's public, but the road to it is private.

    Wow, it’s changed a bit. I wouldn’t go to many SD Lakes or Ponds at night either....

    Seems like some awesome fishermen, women and children can make it safe again!

    Just small bullheads and carp in Libby as far as I know.
    Are you talking about the ponds off old pomerado road? One of them is really small but public and the bigger one is called Taylor pond, it’s private though.

    Scripps Pond has been great for the kids. Our only other free option is Chollas, which has been pretty terrible in our experience. It certainly doesn't help that we almost always see adults fishing by themselves. I can't tell if the city actually cares about enforcing the kids-only fishing, or just unable to.
