There are three perennial streams within the park (Beaver, Highland, and Cold Brook Creeks) for approximately 3 miles of total stream length. There are 94 documented springs within the park. Due to drought conditions less than 1/3 of them are currently flowing. Average precipitation for Wind Cave National Park is 17.76 inches (using 56 year average).
An abundance of parameters are monitored at the Park's air quality monitoring station, including hydrogen, sulfate, nitrate, ammonium, chloride, base cations, ozone, sulfur dioxide, and meteorological data.
There are approximately 300 deer in the Park with about ¼ of them white-tailed deer and ¾ mule deer.
There are between 90-100 Pronghorn in the Park. These numbers may rise as fawns are born (first 2 weeks in June).
During the winter of 2007-8 there were approximately 650 elk in the Park with approximately 350-400 of them remaining in the Park now. There are 46 elk with gps collars on for migration and distribution studies.
There are 350-400 bison in the Park, except between calving season (April/May) and prior to roundup (October) when the numbers may increase to 450-500.
