Blue Earth County Comprehensive Water Management Plan March 4, 2016 Priority Concerns Scoping Document Blue Earth County Water Management Plan 2017-2027 Priority Concerns Scoping Document Submitted to the Minnesota Board of Water and Soil Resources – March 4, 2016 Introduction Purpose of the Priority Concerns Scoping Document Blue Earth County is coordinating the preparation of a Comprehensive Water Management Plan in accordance with the “Comprehensive Local Water Management Act,” Minnesota Statute 103B.301 to 103B.315. Before writing the water management plan, the county must identify priority local water management concerns and prepare a Priority Concerns Scoping Document. As defined by Minnesota Statute 103B.305, ““Priority concerns” means issues, resources, subwatersheds, or demographic areas that are identified as a priority by the plan authority.” The process for identifying the county’s priority water management concerns involved 1) notifying local units of government in the county and region and state review agencies that the county is updating the water management plan and inviting those interested to submit lists of priority concerns to the county, 2) a public survey and meeting, 3) meetings with local stakeholders, and the 4) water plan task force. In accordance with Minnesota Statute 103B.312, the Priority Concerns Scoping Document must contain (1) a list of proposed priority concerns the plan will address, and 2) a description of how the priority concerns were chosen. Priority Concerns Scoping Document Review and Approval The Priority Concerns Scoping Document is submitted to the Minnesota Board of Water and Soil Resources (BWSR) for review and approval. The BWSR requests all counties’ Priority Concerns Scoping Documents use the same format and outline. Page 1 General Description Blue Earth County is located in south-central Minnesota approximately 75 miles southwest of the Twin Cities. The County is 765 square miles in area and had a population of 64,013 in 2010 according to the U.S. Census. The Minnesota River forms most of the northern border of the county. Located on the Minnesota River, the City of Mankato is the county seat and largest city in the county and the region with a population 41,198 in 2010. The County contains the confluence of three major rivers: the Le Sueur River, the Watonwan River, and the Blue Earth River. The Blue Earth River joins the Minnesota River at the “bend” in the Minnesota River in Mankato. Agriculture dominates the County’s landscape as over 70- percent of the land in the County was used for cultivated cropland according to the 2012 United States Department of Agriculture’s Census of Agriculture. Page 2 County Population According to the Minnesota Demographic Data Center, the county population is 65,620; with 79 percent (52,237) living in municipalities. The rate of population growth in the County since the year 2000 has increased at a faster rate compared to previous decades. Much of the growth has occurred in the cities of Mankato, Eagle Lake and Madison Lake. Mankato had the greatest population increase, while the percent of population increase in Eagle Lake was higher. Mankato’s population grew from 34,427 in 2000 to an estimated 41,128 in 2014 according to the State Demographic Data Center. Eagle Lake population grew from 1,787 in 2000 to an estimated 2,779 in 2014. Madison Lake grew from a population of 837 in 2000 to an estimated 1,137 in 2014. Population changes in the past fifty years show a clear shift in population from unincorporated areas in townships to municipalities. Figure 1 shows population changes between 1960 and 2010. This trend is common throughout agricultural regions of Minnesota as farms increased in size providing direct farm income to fewer people. In 1960, 33 percent of the total population was in townships. By 2010, townships represented 22 percent of the county population. While the total population of cities grew, the total population of the townships remained somewhat consistent. In 1960 the total township population was 14,512 and in 2010 the township population was 14,107. Population growth in the townships has been in the townships closer to Mankato. More recently, Lime Township’s total population was reduced by an estimated 365 from 2010 to 2014 as subdivisions adjacent to the City of Mankato were annexed to the city. Jamestown Township also lost population from 2010 to 2014 as subdivisions around Duck Lake and Ballantyne Lake were annexed to the City of Madison Lake. Maps 2 and 3 and Table 1 show these population changes in each city and township. Figure 1.

Their projections completed in 2014 projected that the county population would be 64,445 by the year 2020. A year later in 2015, the Demographic Data Center released their population estimates which showed the 2014 county population was estimated to have already exceeded the 2020 projected population. The 2014 estimate for the county population was 65,620. Figure 2.

Natural features, such as lakes and rivers, play a significant role in the county’s development patterns, land management and conservation.
