This facility's 20 large, rectangular ponds have been phased out, but several of the ponds are seasonally full and a new observation deck has been built overlooking one of the ponds. It hosts a variety of waterbirds, including whistling-ducks, cormorants, Anhinga, and an occasional Ringed Kingfisher. During summer, watch for Least Tern and Least Bittern. Trees around the facility attract Great Kiskadee, Couch's Kingbird, and Altamira Oriole. During summer, listen for Groove-billed Ani and Northern Beardless-Tyrannulet. Summer visits have yielded 11 species of dragonflies and damselflies including the Caribbean Yellowface and the decidedly local Spot-tailed Dasher, both of which are limited to several counties in the U.S.
