Channel Patrol


Channel patrol surveys are used to get a status of the probable river depths that could occur at low water over a large area. This type of survey consists of three lines of depth soundings parallel to the flow of the river. One line is down the center of the navigation channel and the other two lines are along the right and left sides of the navigation channel. If the surveys show areas that could be problematic for the navigation industry, more detailed pre-dredge surveys of the problematic areas will be completed.
