LECLAIRE, Iowa — The National Transportation Safety Board says human error is to blame for a sunken towboat in the Mississippi River.
It happened near LeClaire on November 25th, 2013.
The NTSB says the pilot of the Stephen L. Colby navigated into water that was too shallow and hit an underwater rock. The boat began taking on water but the nine crew members aboard were not injured and were able to get off of the boat safely.
The boat was carrying 100,000 gallons of petroleum products, which began to leak into the river. Cleanup crews worked to contain the spill.
The boat had nearly $4 million worth of damage.
