The US Army Corps of Engineers Pittsburgh District is working with the Pennsylvania Fish & Boat Commission to investigate cause of a recent fish kill at Youghiogheny Lake.

It is estimated that approximately 200 fish, mostly non-game (white suckers) died along with a few walleye and one pike. They were found between Big Bend Boat Club and Mays Point. Additional fresh fish were discovered Monday and samples are being taken for further investigation.

Similar fish kills in September 1991 and 2005 were the result of low water levels, sustained high air temperature and warmer water temperatures.

District Biologist conducted a water survey Sept. 5 and found higher than normal pH and dissolved oxygen levels during the day and lower than normal levels at night. Anoxia, the absence of oxygen, was also discovered at 35 feet which is the shallowest depth on record.
