We used six polymorphic microsatellite loci to investigate a potential metapopulation system in bull trout (Salvelinus confluentus) from five spawning localities in the Lightning Creek drainage, a tributary to Lake Pend Oreille, Idaho. The number of spawners as estimated by redd counts is low in all populations sampled. Analytic viability models indicate that local isolated populations of these sizes are unlikely to persist. We tested two hypotheses: (1) these are remnant populations that are vulnerable to local extinction, or (2) these populations are interconnected by migration and are being maintained at larger effective sizes than indicated by the redd counts (i.e. metapopulation dynamics). All populations within the Lightning Creek basin an significantly differentiated (P
