This picture was taken from the spillway overlook on the north shore in the spring of 2009. The US Army Corp of Engineers was testing the newly completed gas abatement project more commonly called the flip lips, because they resemble a kids slide in the park. As the water hits the bottom of the spillway it enters the tailwater elevation pushing itself along the top surface keeping the nitrogen near the surface instead of at the bottom of the river. You notice the rooster tail it creates when it hits the flip lip at the bottom of the spillway.
