Santee Basin Diadromous Fish Plan

American Shad Blueback Herring Hickory Shad American Eel

South Carolina's Santee River system (aka – Santee Basin) currently supports some of the largest populations of diadromous, migratory fishes on the east coast including the American Shad. Keeping that fishery alive means keeping the Santee Basin healthy and restoring access to fish spawning areas.

Diadromous fishes, which must access both marine and freshwater habitats to complete their life cycles, are important for a number of economical, ecological, and recreational reasons. Some species, such as American Shad, Blueback Herring, Hickory Shad, and American Eel, are important commercial and recreational fisheries, while others, such as Atlantic Sturgeon and Shortnose Sturgeon, are endangered.

Populations of all diadromous fish species in the Santee Basin remain depleted compared to historical levels due to a combination of habitat loss and degradation and impediments to spawning migrations and spawning habitat. For this reason, the National Marine Fisheries Service, the North Carolina Wildlife Resources Commission, the South Carolina Department of Natural Resources, and the US Fish and Wildlife Service recently updated the Santee Basin Diadromous Fish Plan aimed at improving the habitat of diadromous species and restoring access to former spawning and maturation sites.

Plan Accomplishments

Since establishing the original Santee Diadromous Plan in 2001, a number of significant accomplishments have resulted to include:

2017 Plan Update

The Santee Diadromous Fish Plan was updated in 2017 with the goal of building on the prior accomplishments and continuing coordination of efforts to protect, enhance and restore diadromous fish populations in the Santee River Basin with Plan objectives to include:

Partnership and Contacts

The four named agencies, listed below, are working in partnership to accomplish objectives of the 2017 Plan. The partnership also includes the utilities operating hydroelectric facilities in the Santee Basin, such as Duke Energy, Lockhart Power, City of Columbia, Santee Cooper, and SCE&G, as well as other federal, state and local agencies with interests in the diadromous fishes of the Santee Basin.
