Where the Tides have Returned

A new article highlighting the tidal restoration at Lookout Slough in Solano County from the Bay Nature Magazine features insights from Mason Rogers, a specialist at CWS and lead of the North Delta Arc of Native Fishes Project.

Rogers delivers insights into the fish community at the newly restored wetland. Sampling immediately post-restoration showed high catches of pelagic (open-water) fish species. Even after pelagic catches declined in subsequent months, the team still found native species, such as Sacramento Splittail (Pogonichthys macrolepidotus), using the restoration. Rogers and CWS Senior Researcher, John Durand, also discuss zooplankton, aquatic plants, and connectivity with surrounding waterways at Lookout Slough.

Sampling from the North Delta Arc of Native Fishes Project continues monthly and the fish community of Lookout Slough will be closely studied in the years to come.
