Highlight 8-7 Determining Target Distance Limit

For a river, the TDL is 15 miles downstream from the PPE.

For a lake, ocean, or coastal tidal water, direction of flow is not considered. The TDL is drawn as an arc with radius of 15 miles.

If the TDL for a water body includes both a river/stream and an open water body, the sum of the downstream distance and radius of the arc equals 15 miles.
