Sand Creek, a 36.6-mile-long tributary of the Minnesota River, winds its way through Le Sueur and Scott counties before meeting the river about a quarter mile downstream from this bridge and just north of Jordan. The creek earned its name from the prominent white sandstone rock formations nearby.
Before merging with the Minnesota River, Sand Creek passes through the Louisville Swamp Unit, playing a crucial role in the area's hydrology by influencing how water moves through the swamp. The surrounding landscape is a classic floodplain that floods approximately three out of every five years, which is vital to maintaining the region's unique ecological balance.
To help manage this, a water control structure was built to regulate the outflow of water into Sand Creek, but it was washed away by flooding sometime between 2011 and 2014.
