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

“How do I get my dataset or application featured in the Inland Water Channel?” Role of channel steward
still is developing• Absolute monarch (at least now)
Contact our fearless leader:• Ken Lanfear, Channel Steward• [email protected]
• Be nice to me! ☺• Need broader base…
In my castle in Scotland ☺
