On March 15-16, 2006 Bill Burger, Curt Gill, Natalie Robb, Cori Carveth and Craig Woods surveyed the upper section of Mineral Creek from the ASARCO Dam to the headwaters at Government Springs Ranch. This section of Mineral Creek was surveyed in 2000 and 2002. Gila chub, longfin dace and green sunfish were reported in 2000 however since then no fish have been observed in the upper section of Mineral Creek. Suitable physical habitat currently exists for native fish species however it is unclear whether high flows or some form of contamination caused the extirpation of fishes from this section of stream. Lowland leopard frogs, Sonoran mud turtles and a mixture of invertebrates were observed on this survey. We would recommend re-introducing longfin dace to the upper section of Mineral Creek to determine its suitability as habitat for native fish species.
