An algae bloom appears to be the culprit behind dead fish found floating in the Inner Harbor yesterday morning, according to state environmental investigators.

The fish kill – the second in the harbor in two months attributed to an algae bloom – was first reported by residents who complained about a stench Monday night. Most of the fish appeared to be scattered on the south side of the harbor near the marina and Rash Field.

There were other fish closer to the Constellation, including some that washed up onto the concrete barrier. Investigators also found dead fish at Rock Creek, a tributary of the Patapsco River in Anne Arundel County, where officials said the water was colored red and brown, an indication of a high concentration of a certain type of algae. Water samples taken from the creek are being tested.
