I talked to a couple of people at Centennial Park yesterday and they both talked about a fish kill about 3 weeks ago. Anyone have any knowledge of what happened? I did see some carp moving around so there is still some fish left.
About 1.5 weeks ago I was there and there were signs up that fishing is closed. Talked to some dude that talked to a ranger, told him they messed up the fertilizer for the grass(too much) and then it rained. Bunch of dead trout, bass, walleye. I caught nothing in normally good areas.... Not sure who is to blame here but it sounds like some company should be paying to restock the lake....

Yea, the money from our fishing license will, they dont care that they ruined the lake. Sad and it's true. Never fished it so I'm not too sad, but it sucks to hear when a fishery gets ruined by something you could have prevented.

Many, however not all, fish kills within the summer result from low concentrations of dissolved oxygen within the water. Fish, like all alternative complicated life forms, need oxygen to survive. They get theirs within the sort of oxygen gas dissolved within the water.

No one seems to know for sure what happened other than there was a fish kill of some kind and the number of dead fish is unknown. This lake is an old gravel pit which is up to 40 to 50 foot deep and some bottom moss but not very many weed beds or other vegetation so it changes temperature very slowly. The ice stays only for a short time during the winter and the lake is usually ice free by early February, so I don't think the lake would have a sudden turn over to cause that kind of damage. I'm still working to find the truth and I have a couple of calls to make this week that may shed some light on this mystery.

I finally talked to someone from the city that knew about the incident. The lake did a sudden turnover due to the extreme change in temperature we had in late September. There were more bottom weeds than I believed there was in the lake and that helped account for the low oxygen level when the lake did it's turnover. The weeds had been accumulating on the bottom for years and the sudden turnover stirred up all that waste and low oxygen level in the water down there then killed up to 90% of the fish as it moved thru the water toward the surface. The lake will be restocked sometime in the future.
