Pittsburgh Bureau of Fire responded to reports of a houseboat on fire on the Allegheny River near 100 Mazeroski Way around 5:50 a.m.
A River Rescue crew member reporting to work observed smoke coming from the docked boat.
River Rescue personnel initially utilized fire extinguishers to control the fire until firefighters responded with Engine 37, Truck 32, Battilion Chief 1, and Fire Boat 1. The fire was extinguished within 30 minutes. The boat was not occupied. No one was injured.
