Water/Sediment Control Basins to detain runoff/sediment
Runoff Risk Assessment:Fields where runoff
control is most needed
Riparian Assessment:Match buffer designs and
landscape settings
IN FIELDS:Place water control /
filter practices
BELOW FIELDS Place water
detention / nutrient removal practices

ecosystem function and nutrient removal

Agricultural Conservation Planning FrameworkOUTLINE OF INITIAL PRACTICE PLACEMENT ASSESSMENTS FOR BEARGRASS WATERSHED
Denitrifying Bioreactors above field-tile outlets where
ditches are deep
Shallow wetlands in near-stream depressionsNovel, site-specific designs
Two-Stage DitchesShallow ditches easily widened
APPLICATION: Scenario development and assessment guided by landowner participants implement/ monitor/ adapt
Surface Intake Filters (e.g., Blind inlets) in depressions
Grassed Waterways to slow concentrated flows
