Karst Features

Caves – there are numerous caves in Boone County.  The most notable is the Devil’s Ice Box (above, right) in Rock Bridge Memorial State Park.  Other caves include Connor’s cave, Hunter’s cave, Tumblin cave, and Rocheport cave. 

Sinkholes – There are 418 documented sinkholes in Boone County.  The majority of these are located south of I-70, in two distinct areas, one is south of Rocheport, and the other is around Pierpont.  The sinkholes are relatively stable, but do discharge to the cave system and groundwater, therefore extreme care should be taken when developing in these areas.    

 

Water Resources 

Bonne Femme Creek Boone County, MissouriHinkson Creek Boone County, Missouri

Missouri River - At 2,300 miles the Missouri River is the longest river in the United States. The river's catchment area consists of over 529,000 square miles - one-sixth of the country's land area. With an average depth of 35' the river has a median discharge rate of just under 59k cubic feet of water per second at its confluence with the Mississippi River at St. Louis, Missouri. The river forms the southwest border of Boone County.

Perche Creek - running through Boone County from the extreme northwest corner to its confluence with the Missouri River in the southwest Perche Creek is a haven for recreational uses in the county.

Bonne Femme (above left) - French for "good woman" the Bonne Femme plays a critical role in the creation of the county's Karst features. Beginning in the east central portion of the county the Bonne Femme runs through the heart of Rock Bridge Memorial State Park. The Bonne Femme, a historically vital stream, is the site of early rural industries such as grain mills, tanneries and breweries.

Hinkson Creek - Hinkson Creek (above right) is a dynamic stream system, with a drainage area of 90 sq. miles or 57,445 acres. The Hinkson Creek watershed runs from the city of Hallsville in north central Boone County to the town of McBaine in west central part of the county. This creek runs southwest through agriculture and pasture land, previous mining land, and urban land. At 32 miles in length the Hinkson runs through the heart of Columbia. Ongoing efforts are being made to remove 11 miles of the Hinkson from the Evironmental Protection Agency's list of imparied streams (303).
