    1 Cougar Dam is a barrier to coho salmon only. Chinook salmon are trapped and hauled above the dam.

    2 Big Cliff Dam is a barrier to coho salmon only. Chinook salmon are trapped and hauled above the dam.

    3 Capay Dam was selected as the upstream extent of EFH because it was identified as a complete barrier by NMFS biologists and is located in the vicinity of the historical upstream extent of Chinook salmon distribution.

    4 Natural “lower falls” are downstream of any artificial barriers that would meet the criteria for designating them as the upstream extent of EFH; therefore, the upstream extent of EFH within this HU is at the “lower falls”.

    5 EFH for Chinook salmon in the Middle San Joaquin-Lower Chowchilla HU (18040001) and Lower San Joaquin River HU (18040002) includes the San Joaquin River, its eastern tributaries, and the lower reaches of the western tributaries. Although there is no evidence of current or historical Chinook salmon distribution in the western tributaries (Yoshiyama et al. 2001), the lower reaches of these tributaries could provide juvenile rearing habitat or refugia from high flows during floods as salmon migrate along the mainstem in this area.

    6 EFH for coho salmon in the Monterey Bay HU does not include the sections south of the Pajaro HU (18060002).
