I believe that is called a chord. Yes, a chord is the straight line segment that crosses a circle, from one side of the circle to the other. The biggest possible chord is the diameter. The curved part of the circle, cut off by the chord [or chords], is the arc or the angle.

First off, what you appear to be asking for is the circumference, the length of area around a circle(or in this case, a body of water). To find the circumference, measure for the diameter, the diameter is the length of one side of a circle to another, this distance must go through the center of the circle. All you have to do is multyply the Diameter by pi.
