Root River

About

Lanesboro Dam — Oldest Surviving Historic Dam in Minnesota. The Root River begins at roughly 43°48′24″N 92°10′14″W in the rugged Driftless landscape of southeastern Minnesota, a region left unglaciated and defined by dramatic limestone bluffs and spring-fed streams. From that headwater it runs 80 miles east and south through Fillmore and Houston counties before reaching the Mississippi River near 43°45′43″N 91°15′06″W. The Driftless terrain gives the river its distinctive geological story: countless small tributaries gather across the bluff country before the long run to the Mississippi.

Long before milling and railroads, the Root River valley was Dakota (Sioux) territory. The limestone bluffs and spring-fed streams of the Driftless Area sustained communities here for thousands of years. Accounts of the river's name diverge — one traces it to the Dakota word for the tangle of tree roots along its banks, another to the reddish clay that lines its bottom — but both root the name firmly in the land itself.

The river's defining moment came in 1868, when the Lanesboro Townsite Company built a stone dam across the Root at Lanesboro, in Fillmore County. The dam powered the town's flour mills and supported the Southern Minnesota Railroad as it pushed into the region. The structure proved remarkably durable: the Lanesboro Dam still stands today as the oldest surviving historic dam in Minnesota. Around the same era, the watershed fed a broader forest economy. From the 1830s through the 1920s, the Root River watershed was logged to supply the regional timber industry and the railroad expansion of the 1860s through 1910s, worked by local sawmills, logging drives, and downstream lumber operations. The exhaustion of old-growth stands around 1910, the start of state forestry conservation in 1915, and the establishment of state forests in the 1930s brought large-scale logging to a close.

The river also drew some of the earliest hydrological study in the region. USGS surveys from the 1870s through the 1890s, gauging-station work from the 1880s through the 1910s, and state geological streamflow assessments from the 1910s through the 1930s made up the first comprehensive picture of the Root River's flows. Later state water-pollution studies from the 1950s through the 1970s, and Clean Water Act assessments from 1972 onward, addressed more than a century of logging, agricultural, and industrial impacts, with restoration and TMDL programs the major present-day outcome.

The river's modern identity took shape in 1984, when Minnesota converted the abandoned Chicago Great Western Railway corridor along the Root into the Root River State Trail, a paved rail-trail connecting Fountain, Lanesboro, Whalan, and Houston. The trail transformed Lanesboro from a declining farm town into a thriving arts and outdoor-recreation destination. Today paddlers commonly run the river in three stretches: Chatfield to Lanesboro, 25 miles through the finest blufflands scenery; Lanesboro to Whalan, a 10-mile trail-corridor run past the artsy town; and Whalan to Houston, 30 miles through a wider valley of bluff country. Root River Outfitters in Lanesboro rents canoes, kayaks, and tubes for those looking to get on the water. What began as an engine for grist and commerce now anchors one of the state's most cherished bluff-country corridors.
