ML, it is a beautiful little pond, first time going was when I saw it last month. I asked a park attendant who managed their pond; got a blank stare. it is really unfishaable. If you are ever near there, maybe you can identify the weed and offer them a solution. I sent Kelly a P mail because he was looking for a test pond, but didnt get a response; but looks like he has a good candidaate. The Challenger pond is crystal clear, you can see many small RES, but cant drop a hook, seriously. People I saw fishing were fishing in Clear Creek. Might catch a hard head.
