maximum Strahler number
highest Strahler number of a stream, creek, or river

Description	Strahler number, reflecting the size of a river, according to the number and size of its tributaries. A level 1 stream has no tributaries, a level 2 stream has only level 1 tributaries, a level 3 stream has level 2 tributaries, and so on. But in the example of the level 3 stream, it is only a level 3 stream above the confluence of two level two streams, which in turn, only apply to streams downstream of their first tributary. Hence the multiple values in the example below. coordinate location (P625) could possibly be used as a qualifier to indicate what parts of the stream have what Strahler number (an item won't work because the first tributary of any given stream is not always notable).
