Challenges

Agency support is highly variable

Delineation methods vary state to state

Addressing cooperators needs to preserve existing watershed boundaries

Inconsistent funding

Edge-matching

SSWD

Technical WBD Coordination - SSWD

Ensure communication between Federal, State, local

Assess progress in each state

Offer guidance on delineation method for states

Ensure compliance with the National Guidelines

Facilitate edge matching between states

Provide supplemental datasets that expedite delineations

Organize and attend workshops and training sessions
