Zumbro River Comprehensive Watershed Management Plan
Greater Zumbro River Watershed Comprehensive Watershed Management Plan Waterside Chats Summary Summary The Greater Zumbro River Watershed Partnership hosted “Waterside Chats” in three communities throughout the watershed in October and November 2019. Waterside Chats were held on October 24th, 2019 at the Zumbro Valley Recreation Club in Mantorville, November 7th, 2019 at the Community Center in Mazeppa and November 14th, 2019 at the Sportsman’s Club in Lake City. The public was asked to attend the Waterside Chats to learn about the issues that had been identified by local partners and to provide feedback with their local knowledge of the watershed. Each Waterside Chat began with an overview presentation by the local SWCD or County Staff which included a summary of the One Watershed, One Plan program and plan development process, a summary of what has been accomplished, and information on how the public can participate. Following the overview, Barr Engineering summarized the priority resources and issues that had been identified in local and state plans, studies, reports, state agency feedback, and resident surveys. Initial results of the prioritization of these issues identified by a survey of watershed residents and ranked by the policy committee, planning workgroup and technical advisory group was also shared to aid in the table conversations (see figure 1 below). Following the presentation, attendees were broken into small groups. Each small group discussed a series of questions to provide their input and feedback on the list of priority issues to be addressed in the 10-year scope of the plan. Comments were captured by a facilitator from the planning partnership, summarized, and reported out to the large group.

FINAL REPORT: THE 2016-2017 ROADSIDE VEGETATION SURVEY OF SCOTT COUNTY, IOWA Submitted by Leland M. Searles, Owner Leeward Solutions, LLC December 25, 2017 Bob Bryant photographs Sullivant’s Milkweed in a Scott County roadside. Sullivant’s Milkweed is uncommon, but, like other milkweeds, it attracts Monarch butterflies for egg-laying and food. Bob joined the survey in 2016 and 2017 as a field assistant and expert on the county’s flora and botanical history.

The RVS occurred in two phases, with hard-surfaced roads surveyed in 2016 and gravel roads driven in 2017. Level B and C roads were not included, with only a few exceptions. The field component was completed in early September 2017. This final report contains information and conclusions based on both phases. The survey began on July 25, 2016, with training on GPS equipment.
