Catalyze evolution from Stage 6 to Stage 8. Raise water stage and water table at base flow; increase riparian vegetation and woody shrub cover; expand aquatic habitat and wetland footprint; increase water and sediment retention. Maybe someday, probably decades from now, a beaver complex (like neighboring reference streams). We can hope.
Sod speedbumps (native riparian sod was stacked to create speedbump structures across inset channel, raising stage and inducing out-of-channel flow). Other important PBR treatments included livestock management and planting 2000 willow saplings.
