Around 8:30 PM, the culvert gave way, releasing the pent up floodwaters into downtown Erie. The flood traveled through the city at 25 miles per hour (11.2 m/s), leaving a path of destruction 3 miles (4.8 km) long and 6 blocks wide. In all, 225 houses were damaged or destroyed, along with over 300 other buildings and 36 fatalities. To prevent another flood, the city enclosed the Mill Creek in a concrete tube running underneath the city.
