Turtle Bayou is the northern most cut between Redfish Bay and Aransas Bay at the northern eastern end of Estes Cove. The pass itself has silted in and may not be passable for many boats, but fish still use it as a main thorough fare between the two bay systems. On the Aransas Bay side, there is a nice drop off with grassy areas sloping from Talley Island out to the deeper waters of Aransas Bay. On the Estes Cove side, the cut runs back and connects to the channel that leads out to the Intracoastal Waterway (ICW).
Depending on the season, the fish will be in the cut, along the grassy edges of the cut or moving up onto the grassy flats to ambush bait. This area holds good populations of speckled trout, redfish and flounder with spanish mackerel showing up in the summer on the Aransas Bay side.
