Comments
General Comments: 
Impacts: 3 headcuts, encroachment, channel incision in last 3/4 of meadow -3 headcuts all with low movement potential draining small portion of meadow and entering main channel. -heavily encroached in West side of meadow. Historic photos show less encroachment in 1988 and 1949; Lower 1947, 1990 -main channel becomes more incised 3/4 down meadow (2-4 ft). Not sure if incision is human caused or because of topographic constraints. -banks some slumping in main channel and erosion
