Why Potomac River is split up
The freshwater upper river and tidal lower river are different fishing systems and need separate depth context.

Same child-page contract
What every section keeps separate
- Depth provenance: each child discloses whether its contours are survey-backed or modeled; a family card never upgrades that label.
- Fishing spots: structure and seasonal recommendations are calculated inside the child boundary so distant reaches are not mixed together.
- Fish species: each page keeps its own supported roster rather than inheriting every species found anywhere in the parent system.
- Local context: hatch guidance, access, hazards, catches and nearby-water links continue to resolve for the individual child where data is available.
