- Significant increase in riparian vegetation; riperian vegetation. Big floods in 1983, and has increased since then.
- 1980 infrared photos show that riparian vegetatin had taken up much of the flood plain down to power plant capacity flow levels.
- 2013 USGS Report to AMWG--
- More riparian vegetation exists than in previous 5 decades at the lowest elevation zones (<45k ft3/s)
- Riperian woody vegetation expanded shoreward
- HFEs of present magnitude/ duration do not appear to affect the longer term trend of expansion
- Vegetation change is significantly related to river hydrology at lower elevation zones (<45k ft3/s)and regional climate at higher elevations (>97k ft3/s)
- Remote sensing datasets allow both large-scale change detection and local-scale analysis to quantify
