Elevation reference

Elevation reference describes how a published height is expressed—such as MSL phrasing on summaries, or pool-relative wording—alongside the vertical datum. Lake Insights shows it separately from NGVD 29 or NAVD 88 where catalog metadata provides it.

Why it matters

Two lakes can both list NAVD 88 but describe elevations differently in prose. Reading only “datum” misses how the operator phrases the number on public tables—important when merging sources.
