Why Lough Foyle is split up
Trip-scale operational children keep channels, banks, island passages and access context readable while retaining only official source cells that pass the fixed release gates.

The released set contains 3 survey-backed sections and 0 modeled sections. Their published maximum depths run from 48 to 77 ft, with a median of 67 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.
Why is Lough Foyle divided into separate fishing maps?
Trip-scale operational children keep channels, banks, island passages and access context readable while retaining only official source cells that pass the fixed release gates.
Are these depth maps survey-backed?
3 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.
