How to Play

You're looking at a HUC-6 watershed basin, shown as just an outline. Can you name it?

Each wrong guess reveals a new data layer:

• 1 Boundary outline
• 2 Mainstem river
• 3 Tributaries
• 4 Land use (NLCD)
• 5 Satellite imagery
• 6 Surrounding watersheds & states

Fewer layers = higher score. Everyone gets the same watershed each day.

Scoring: 6 pts (layer 1) → 1 pt (layer 6) → 0 (fail)
