Note from the Program The Minnesota Department of Natural Resources (DNR) is pleased to submit the 2019 Invasive Species Annual Report to the governor, legislature and people of Minnesota. This report summarizes our efforts to prevent the introduction and spread of invasive species of aquatic plants and animals in Minnesota. The report provides an overview of program activities, finances, prevention and management efforts, goals, highlights, partnerships, and future needs and plans for individual program areas.

The report highlights the accomplishments of the Invasive Species Program and keeps you up to date with new issues facing the program as we work to reduce impacts of invasive species on Minnesota’s outdoor traditions. Great work was accomplished in 2019, with the help of our partners. Some highlights include: • An increase to the Aquatic Invasive Species (AIS) surcharge on watercraft licenses from $5.00 to $10.60 was passed during the 2019 legislative session. This increase addresses the fund deficit and will allow the Invasive Species Program to reinstate at least $400,000 in invasive aquatic plant management grants, increase support of watercraft inspectors around the state, and respond to newly discovered zebra mussel and starry stonewort populations. • Invasive Species Program staff issued 341 permits to control invasive aquatic plants, completed 71,019 watercraft inspections and trained 922 local government watercraft inspectors who accomplished an additional 439,981 watercraft inspections. Invasive Species Prevention Planners provided technical support to counties who received AIS prevention aid, while building a community of practice to enable county partners to work together and leverage funds. Staff worked with the public at lake association meetings, the Minnesota State Fair, conferences, and outdoors shows and financially supported the inventory and management of terrestrial invasive species on 6,186 acres of state and adjacent land. Conservation officers completed 11,253 hours of invasive species education and enforcement. • In June 2019, the DNR, with funding from the Great Lakes Restoration Initiative administered by the U.S. Fish and Wildlife Service, worked with partners at the University of Minnesota, the U.S. Fish and Wildlife Service, and the U.S. Geological Survey to organize a meeting about the scientific, legal, and public participation aspects of genetic biocontrol technologies for invasive species. The Invasive Species Program will continue to look for ways to continue to engage partners in further discussions. • The DNR Invasive Species Program, with funding from the Great Lakes Restoration Initiative administered by the U.S. Fish and Wildlife Service, worked with a contractor on a project to better understand motivations and barriers associated with AIS. The outcomes of this project will include recommendations and strategies to promote the adoption of desirable AIS prevention behaviors and create positive social norms around AIS prevention in Minnesota, including pathways such as bait and water gardens. • To gain deeper understanding of natural resource issues important to Minnesotans, the DNR and the AIS Advisory Committee hosted three public events around the theme: What can we do to more effectively address the issues of promoting access to Minnesota’s Lakes and Rivers, providing excellent recreational fishing, and stopping the spread of aquatic invasive species? Thank you for partnering with the Invasive Species Program this year. We look forward to working with you in 2020 as we search for new technologies, create new partnerships, and strengthen current partnerships to protect Minnesota from invasive species. Heidi Wolf, Invasive Species Program Supervisor Minnesota Department of Natural Resources 4 Program Overview Invasive species have serious economic, environmental and recreational impacts in Minnesota. In 1991, the Minnesota Legislature directed the DNR to establish an Invasive Species Program. The program is tasked with preventing the spread of invasive species and managing invasive aquatic plants and wild animals (Minnesota Statutes 84D). In 2019, the Invasive Species Program included 23 full-time positions, plus affiliated staff in DNR offices across Minnesota whose work is primarily or partly focused on invasive species. In the summer, the DNR hired 86 watercraft inspection staff. GOALS Program staff work with many partners, including: • Prevent the introduction of new invasive species into Minnesota. • Local government units. • Prevent the spread of invasive • Tribes, states, provinces, multi-jurisdictional and species within Minnesota. national groups. • Reduce the impacts caused by • Researchers, including the Minnesota Aquatic Invasive invasive species to Minnesota’s Species Research Center (MAISRC) and the Minnesota ecology, society, and economy.

Norvitch ABSTRACT The alluvial channel deposits described in this report are in Nobles County, Minn., about 150 miles southwest of Minneapolis and St. Paul. Although four municipalities and many farms obtain part or all of their water needs from the alluvium, it has not yet been fully developed for ground water. The extent of the alluvial channel deposits was mapped on high-altitude aerial photographs, and a power auger was used to bore 43 test holes to determine the thickness of alluvium and the water level at each of the test sites.

    USDA-NRCS IOWA STATE TECHNICAL COMMITTEE MEETING Neal Smith Federal Building 210 Walnut Street, Room 693 Virtual Meeting - Teleconference Des Moines, Iowa 50309 September 17, 2020 at 1:00 P.M. DRAFT MINUTES Welcome/Opening Comments – Kristy Oates, Acting State Conservationist Kristy opened the meeting, expressed her appreciation for everyone attending virtually, and roll call was accomplished (Attachment A). Kristy stated that she is on detail from Texas and it was announced today that Jon Hubbert has been selected as the new State Conservationist. Jon will begin his duties in that position on October 11, 2020. Kristy reported that there are several postings currently on the federal register: • USDA is seeking nominations for the Task Force on Agricultural Air Quality Research; • USDA is seeking input for Ready to Go Technologies and Practices for Agriculture Innovation Agenda, and; • The rule was posted for determining whether land is considered highly erodible or a wetland which followed the interim final rule published December 7, 2018. • Of note, additional information on the Air Quality Task Force and Ready to Go Technologies and Practices will be posted on the State Technical Committee page of the Iowa NRCS website. Kristy also reported that in response to the derecho storm event, NRCS developed a special EQIP signup for seeding cover crops on impacted fields, replacing roofs, covers, or roof run off structures previously funded through NRCS and replacing damaged high tunnel systems previously funded through NRCS. Producers may request early start waivers to begin implementing practices immediately. Landowners with windbreak and shelterbelt tree damage may apply for NRCS assistance through general EQIP.

RYAN Contributions to the Hydrology of the United States, 1914-I WASHINGTON. GOVERNMENT PRINTING OFFIOE 1915 GAZETTEER OF SURFACE WATERS OF lOWA. By W. G. HoYT and H. J. RYAN. This gazetteer embraces descriptions of all the streams named on the best available maps of Iowa, including the United States Geo­ logical Survey's base map of Iowa (scale 1 to 500,000), county maps published in the annual report of 'the Iowa Geological Survey, and the topographic atlas sheets of the United States Geological Survey. Each stream is described as rising near the point at which its beginning is shown on the map. This method does not give results of great precision, and all statements of length and course are merely approximate. The letter Lor R, in parentheses after the name of a stream, indi­ cates that the stream is tributary from the left or right, respectively, to the stream into which it flows . .Abby Creek (L); Linn County; rises in T. 83 N., R. 5 W.; flows west 9 miles into Big Creek (tributary through Cedar River to Iowa River and thus to the Missis­ sippi) in Linn County, T. 83 N., R. 6 W . .Ackley Creek (R); Floyd County; rises in T. 94 N., R. 18 W.; flows east 9 miles into Shellrock River (tributary through Cedar River to Iowa River and thus to the Mississippi) in Floyd County, T.
