Army Corps keeps river traffic moving despite frigid temps, icy conditions
Whether it鈥檚 100 degrees outside in summertime or 11 below zero like it was last weekend, the U.S. Army Corps of Engineers鈥� crews are out manning the nearly two dozen locks and dam facilities in its Pittsburgh district keeping waterway traffic moving along the three rivers.
Even as the Monongahela, Allegheny and Ohio rivers freeze during this prolonged cold snap, the Army Corps workers are out 鈥渆xercising鈥� the locks and moving ice through the chambers to maintain a navigable channel.
鈥淎ll of our facilities 鈥� not only on the Mon, but the Allegheny and Ohio 鈥� are fully operational, and that鈥檚 a testament to our crews keeping things running in these cold conditions,鈥� said Alan Nogy, who is chief of locks and dams for the Army Corps鈥� Pittsburgh District. 鈥淥bviously, the first challenge for my guys is the temperature. 鈥� Whether it鈥檚 80 or 18 below, my guys are out there.鈥�
The Army Corps in the Pittsburgh region maintains 22 locks and dam facilities leading to and from The Point. Eight are on the Monongahela extending from Pittsburgh to near Fairmont, W.Va.; eight are on the Allegheny from Brady鈥檚 Bend in Armstrong County; and six are on the Ohio River that extend to Hannibal, Ohio. While the extreme cold over the past two weeks has frozen portions of the Allegheny near The Point, there still remains a navigable channel for the more heavily traveled Monongahela and Ohio rivers.
But even if they鈥檙e not totally frozen over, ice gathering on top of the rivers can cause a blockage, so the crews have to continue operating the locks and move the ice through, otherwise the boats might not fit coming through the chambers.
鈥淛ust like we would lock a boat, we lock the ice and flush that ice through,鈥� Nogy said. 鈥淪ometimes we do it even when the boats aren鈥檛 coming through.鈥�
Their standard wintertime procedures involve 鈥渆xercising the gates鈥� just like a person would exercise a muscle to keep it in shape, Nogy said. He added that there are also 鈥渁ir bubblers鈥� near the facilities to keep ice from building up and so it 鈥渄oesn鈥檛 choke us out.鈥�
鈥淥ur mission is to be open and available 24 hours a day, seven days a week, 365 days a year. We don鈥檛 have anything holding us back for anything coming through our facilities,鈥� Nogy said. 鈥淚ce lockage is just one of the things we鈥檙e doing. Multiple times a day our team is opening locks and gates, draining, doing anything to make sure we don鈥檛 slow down.鈥�
While the Army Corps operates the locks and dam network, the rivers themselves are under the purview of the U.S. Coast Guard. Nogy said the locks and dams system is meant to keep the river navigable and not necessarily for flood control. The locks and dams help elevate or lower boats coming through the rivers as the elevation changes, ensuring the rivers are navigable year-round as water levels change.
鈥淲e are flow control, not flood control on our projects,鈥� he said.
And now with Punxsutawney Phil predicting another six weeks of winter, the Army Corps crews will continue to be out braving the elements ensuring the locks and dam system is operating normally to help keep traffic moving on the three rivers. Nogy said that is a 鈥渢estament鈥� to the workers who man the 22 facilities, no matter the season.
鈥淭here鈥檚 probably a lot of people who live in this region who don鈥檛 realize the importance of river transportation as it relates to moving (commerce) on the rivers and the benefits to our region and nation,鈥� Nogy said. 鈥淚t鈥檚 our responsibility to keep it going. That鈥檚 what we鈥檙e doing day in and day out 鈥� no matter the conditions.鈥�
