Far in the northern forest of Minnesota, about a hundred and ninety miles north-northwest from Minneapolis and St. Paul, there lies a little lake which probably has become known, at least by name, to as many people throughout all civilized lands, as any lake of the whole world. Its pre-eminence comes from its being the bead of the great river Mississippi, which first flows out from it fourteen miles north ward, more nearly thirty miles by the meander­ ing course of the river, and thence fiows to the east through a succession of small and large lakes, and afterward to the south through the central part of this state and along ib southeast boundary and on ward thousands of miles to the Gulf.

  • Minnesota History: Controversy at the Mississippi's Headwaters
    Minnesota History: Controversy at the Mississippi's headwaters By CURT BROWN April 2, 2015 BRIAN PETERSON • [email protected] in modern times: Dawn breaks in Itasca State Park. The park was created in 1888 by the Legislature, a measure that passed by only one vote. Never mind the 8,000-year-old flint-tipped spears that archaeologists link to nomadic tribes that hunted bison and moose near the headwaters of the Mississippi River. And forget about the 800-year-old burial mounds of the Woodland people who predated the Dakota, Ojibwe and the French fur traders — all of whom knew the ins and outs of the swampy, mosquito-infested, creeks and lakes southwest of Bemidji. When it comes to the so-called discovery of the Mississippi’s source, Henry Rowe Schoolcraft not only gets the credit. He landed naming rights in 1832. He combined the Latin words for “true” and “head” — veritas and caput — and dropped a few letters from each end to come up with a new lake name. Lake Itasca is now commonly considered the true head of the mighty river, attracting a half- million stone-stepping visitors annually. But before everyone agreed, the headwaters’ back story was punctuated with controversy, fraud and a young female park director who didn’t back off from gun-totting loggers. Finding the great river’s source wasn’t easy because the Mississippi actually starts off winding north and east before coursing south to the Gulf of Mexico. Cases were made that nearby Turtle River or Elk Lake deserved the source designation.

The river has its source at Lake Itasca, Minnesota, and empes south of New Orleans into the Gulf of Mexico. The Mississippi and its tributaries drain a river basin covering 3,220,000 square kilometres; one third of the USA and the fourth largest river basin on the planet. The famous Mississippi steamboats first traded on the river in the 1820s. Timber, food and coon were carried down the Mississippi.

It is the largest of Minnesota’s 10 major river basins, and is the only major drainage basin with all of its watersheds contained entirely within Minnesota’s borders.

Population growth trends show increasing pressure on the upper part of the basin. • The 4-digit hydrologic unit code or HUC for the Upper Mississippi Basin is 0701. There are dramatic changes in the river as it flows downstream from the headwaters to the metro area. • The Northern part of the River and Basin is dominated by lakes and forests (above the red line). • The Southern part of the River and Basin is dominated by Upper Mississippi River Basin (HUC 4) more agricultural and urban areas (below the red line). These differences in land use dictate the type of water quality issues found across the basin, as well as the specific strategies that are needed to protect or restore the river. 1 Assessments: Is the river meeting standards and providing beneficial uses?

  • Annual Stream Runoff and Climate in Minnesota's River Basins
    ST. ANTHONY FALLS LABORATORY Engineering, Environmental and Geophysical Fluid Dynamics Project Report No. 543 Annual Stream Runoff and Climate in Minnesota’s River Basins by Todd R. Vandegrift and Heinz G. Stefan September 2010 Minneapolis, Minnesota ABSTRACT Stream flows recorded by the USGS from 1946 to 2005 at 42 gauging stations in the five major river basins of Minnesota and tributaries from neighboring states were analyzed and related to associated climate data. Goals of the study were (1) to determine the strength of the relationships between annual and seasonal runoff and climatic variables in these river basins, (2) to make comparisons between the river basins of Minnesota, and (3) to determine trends in stream flows over time. Climatic variables were air temperature, precipitation, the Palmer Drought Severity Index (PDSI), and the Palmer Hydrological Drought Index (PHDI); the latter are common indices of soil moisture. Water year averages showed stronger correlations than calendar year averages. Precipitation was a good predictor of stream flow, but the PDSI was the best predictor and slightly better than PHDI when linear regressions at the annual timescale were used. With an exponential regression PDSI gave a significantly better fit to runoff data than PHDI. Five-year running averages made precipitation almost as good a predictor of stream flow (runoff) as PDSI. A seasonal time scale analysis revealed a logical stronger dependence of stream flow on precipitation during summer and fall than during the winter and spring, but all relationships for seasonal averages were weaker than for annual (water year) averages. Dependence of stream runoff on PDSI did not vary significantly by season.
