ft. Foot subtype not established; no unit conversion is offered.

Values from usace-cwms. No agency endorsement is implied. A changed datum or incompatible series is excluded from comparisons and breaks the chart line.

Captured history uses the reviewed datum interval. Forward refresh requires unchanged exact series, unit, parameter and explicit datum metadata; it cannot prove absence of undocumented historical changes.
