Six hundred and forty‐four trout from 46 streams in the White Mountains of east central Arizona were examined meristically and morphometrically to determine the presence of the native Apache trout (Salmo apache). Evidence for a wider range of morphometric characters than given in the type description of the species was substantiated. Patterns of variation were corroborated by stocking histories and probable behavior of stocked, catchable hatchery rainbow trout (Salmo gairdneri). Based on combinations of three meristic characters, classifications are given for stream populations of trout in the White Mountains for use in the management of this threatened species of fish.
