Gate accessing WWTP

Directions: To reach the WWTP, continue on the Kamehameha Hwy from Fumi’s parking lot for 1.7 miles before taking a left onto the access road. This turn is almost directly across the street from the enterance to Turtle Bay resort. The short access road leads to a fenced in area comprised of four ponds. The gates are almost always unlocked (I’ve never encountered them locked, any day of the week) and birders are welcomed to drive in and view the ponds.

Birds: The southwestern most pond usually holds the majority of the ducks. The typical species present usually include Mallards (resident hybrids), Northern Shovelers, Northern Pintail, Lesser Scaup, Hawaiian Coot, Black-necked Stilt, Ruddy Turnstones, Sanderlings, and Pacific Golden Plovers. Along with the typical fare, it is not unusual for a few other species to be present including American Wigeon, Eurasian Wigeon, Greater Scaup, Tufted Duck, Bufflehead, or Canvasvack.
