Brandywine River

Rivers are larger than mid-sized streams and typically have wide, deep, and gently sloping channels.

Their width allows sunlight to reach the channel, but the water is often muddy and prevents light from penetrating to the bottom.

The blue line depicts the 5th and 6th order river segments in the Brandywine River watershed.

Stream Order	Length (mi)	Count of Segments	% Length
1	148	182	60
2	44	67	18
3	25	42	10
4	15	39	6
5	12	23	5
6	1	1	<1

How many river miles are there? What percent of total stream miles in the watershed does the river segment account for?
