Fish Springs National Wildlife Refuge is located at the southern end of the Great Salt Lake Desert, part of the Great Basin in Juab County, Utah. The Refuge is managed by the United States Fish and Wildlife Service. As an oasis in the Great Basin Desert in western Utah, Fish Springs serves a variety of species including fish, migratory birds, deer, coyotes, pronghorn, cougars and other native species. The reserve can be reached by paved road from Lynndyl, Utah to Topaz Mountain and then by improved dirt road to the Pony Express Road/Lincoln Highway improved dirt road which runs through the Refuge. The Refuge also serves as a recreational area for permitted outdoor activities. The Fish Springs Range runs north to south and is immediately west of the Wildlife Refuge.
Fish Springs started as a Pony Express and Overland Stage station, and got its name from the fish that populated the springs, which were reported to be over 6 inches (15 cm) in length.
The fish are left over from ancient Lake Bonneville which receded about 14,000 years ago. Several natural springs feed the wetlands. These are along a linear path at the range front (i.e. fault controlled), and include North Springs, Deadman Springs, House Springs, Middle Springs, Thomas Springs, South Springs, and Percy Springs. Fish Springs is thought to be the end of a long flowpath of groundwater, starting in the Schell Creek Range and Snake Range area and flowing along permeable bedrock (e.g. limestones) or faults toward Fish Springs. This comes from the fact that the annual discharge of the springs is 27,500 acre feet (33,900,000 m3)/year, and the annual recharge for the drainage area (the range front and Fish Springs Flat) is about 4,000 acre feet (4,900,000 m3)/year, meaning over 6 times more water flows out of the springs than falls in the valley annually by precipitation. The springs and several wells in the area are monitored by Fish and Wildlife personnel and/or the Utah Geological Survey. The water of Fish Springs is not suited for human consumption, being warm (~80 °F (27 °C)) and highly saline.
