    The listing for sediment in Napa River originated from fine sediment impacts to spawning and rearing habitat as noted in the TMDL. The TMDL provides actions to reduce fine sediment input to the non-tidal portions of the main stems and all freshwater tributaries. When the Napa River was a single water body segment, the impairment and TMDL applied to entire main stem segment. Now that we have separated Napa River into tidal and non-tidal segments for the Integrated Repot purposes, we apply the listing for sediment to the non-tidal segments to be consistent with the impairment analyses and implementation actions required in the TMDLs.
