The released set contains 6 survey-backed reaches and 0 modeled reaches. Their published maximum depths run from 46 to 196 ft, with a median of 98 ft. Those numbers make scale differences visible, but they do not make sections interchangeable: contour provenance, access, species evidence and local structure remain specific to each child map.
Start with the section closest to the water you actually plan to fish. Then compare its depth-data label and species roster with an adjacent section before treating a pattern as system-wide. A survey-backed child is the stronger choice for precise breakline planning; a modeled child is broader reconnaissance and should be checked against sonar and conditions on the water. Return to this overview whenever you cross into another mapped reach, pool or coastal section.
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.
Planning questions
Frequently asked questions
Why is Hudson River divided into separate fishing maps?
Named lower-Hudson reaches keep local channel depth, tidal structure and access useful without forcing one enormous river page.
Are these depth maps survey-backed?
6 released maps use surveyed or official agency bathymetry. Each child keeps its own provider, product, datum and not-for-navigation disclosure.
Do fish and access records apply everywhere?
No. Species, forage, access and fishing spots remain scoped to each child map and retain their evidence labels.
