CLPW Flyer & <br />Petetion <br />Curly Leaf Pondweed Control Plan <br />•A team consisting of the Sherburne County Soil and Water Conservation District, City of Elk River <br />Environmental staff and the Lake Orono Improvement Association Water Quality Committee has <br />concluded the best resolution is a managed lake drawdown in the fall to allow a hard freeze kill of <br />this damaging weed. <br />•The water elevation adjustments would be done during the timeframe of mid-to late October in a <br />gradual manner when average daytime temperatures are still 50 –55 degrees Fahrenheit. This <br />technique will facilitate a proper environment for animal species adaptation during this temporary <br />action. The water level would remain down until a hard freeze occurs. <br />•This will allow us to achieve the environmental objective of Invasive Curly Leaf Pondweed <br />reduction while accounting for all desired species survival, most notably, the threatened Blanding <br />Turtles. <br />
