Regarding historical fish populations, the Arroyo Seco is the only major Salinas River tributary which has remained un-dammed and as of 2015, still supported a small remnant population of the threatened Central Coast Steelhead trout (Oncorhynchus mykiss) that once spawned throughout in the Salinas River watershed. At one time it was also an important middle link for salmon migrating from the Salinas River to Tassajara Creek and other tributaries. Estrella River also remains un-dammed. A 2015 assessment of the survivability of the river's steelhead trout indicated that such a survival may be unlikely, due to the river's recent tendency to run dry for most of the year. Other tributaries of the Salinas River that supported steelhead trout once included Paso Robles Creek, Jack Creek, Atascadero Creek, Santa Margarita Creek and Trout Creek in the upper reaches of the River. It once took over ten days for the steelhead from the upper part of the watershed to migrate to the Pacific Ocean near the City of Marina on Monterey Bay. From there, the steelhead would migrate to the area west of the Aleutian Islands before returning to the spawning grounds in the tributaries of the Salinas River. As noted, the trout life-cycle which requires an annual migration to the sea and then back, was broken during the dry-river conditions of the years 2013–2016, and the current fate of the river's steelhead trout remains uncertain at best. Father Pedro Font described salmon in the Salinas River (Rio de Monterey) on the de Anza Expedition in March 1776: ... there are obtained also many good salmon which enter the river to spawn. Since they are fond of fresh water they ascend the streams so far that I am assured that even at the mission of San Antonio some of the fish which ascend the Rio de Monterey have been caught. Of this fish we ate almost every day while we were here. If Father Font was describing salmon (and not steelhead), then his records suggest that salmon once traversed the Salinas River main stem and up its San Antonio River tributary to Mission San Antonio near what is now Jolon. This may support other historical observer records primarily in the form of oral histories
