We conclude that: <br />• we approve of the proposed boundary for the Stubbs Bay LID for the purposes of: <br />o managing existing Aquatic Invasive Species (AIS) and preventing the introduction and establishment <br />of new ones <br />o maintaining the health of the native plant community <br />o monitoring water quality <br />o identifying potential sources of phosphorus inputs to the bay, developing a phosphorus budget, and <br />devising and undertaking phosphorus reduction projects <br />Goals of the Proposed Lake Improvement District <br />The primary goals of the proposed Lake Improvement District for Stubbs Bay are to manage existing and possible <br />future AIS in the lake. Secondary goals of the LID include monitoring for new AIS introductions, maintaining the <br />health of the native plant community, monitoring water quality, and undertaking programs and collaborations to <br />improve water quality. <br />Background Information on Stubbs Bay <br />Stubbs Bay (DOW Lake ID Number 27013312) is an enclosed bay off Lake Minnetonka (DOW Lake Number <br />27013300). It is cut off from the main lake by a very narrow channel into Maxwell Bay (DOW Lake Number <br />27013311) at the southern end. This in turn flows into Crystal Bay and then the Lower Lake'. <br />This LID would include all parcels having direct or deeded access to Stubbs Bay. <br />Lake Minnetonka, and Stubbs Bay, is classified as General Development (GD). In Orono, GD lakes have <br />structure setbacks of 75 feet above the Ordinary High Water Level (OWHL). The City also regulates the <br />removal of vegetation in the Shore Impact Zone (SIZ), including submittal of a revegetation plan and erosion <br />control measures if necessary. <br />278 <br />
