There was concern that sediment produced during the first postfire wet season would degrade pool habitat, thereby adversely affecting the population of steelhead Oncorhynchus mykiss confined to the 4.8-km reach between Rindge Dam and the Pacific Ocean. We tested the null hypothesis that first-year postfire sediment deposition had no effect on pool channel characteristics (depth, area, shape, and surficial sediment particle types) by monitoring pools after the fire but before and after the first postfire wet season. We added field observations of channel morphology to extend the results of the pool measurements. Our findings did not support a suggestion that pool habitat would degrade following the first-year wet season because pool-channel characteristics were generally unaffected by postfire sediment deposition. Consequently, no management action was needed to mitigate the effect of sediment deposition on pool habitat. The amount of soil erosion and sediment deposition that could have been produced during the first postfire wet season may have been reduced by various factors including the burn characteristics, below-average precipitation, and earthquake-induced recruitment of cobble and gravel.
