The <br />goal of the project was to manage invasive plants, particularly curlyleaf pondweed, and improve water clarity. <br />"With the rain we had in September, we knew that we were going to have to get some dry weather in order to make up for the wet starting conditior <br />said RCWD lake and stream specialist Matt Kocian. "As the fall went on and we kept getting rain, we saw our chances diminishing to reach that to <br />elevation." <br />According to the National Weather Service, 2016 was the wettest year on record for the Twin Cities area with 40.32 inches of precipitation surpassing <br />the previous record of 40.15 inches in 1911. This year, 5.47 inches fell in September, 3.41 inches in October and 2.98 inches in November. <br />"For a while we did leave the stop logs on the dam out, hoping that we might hit some intermediate mark and see some benefits from that. So even if we <br />didn't hit our target elevation, we might still be able to draw it down a foot or two and see some benefits," <br />Kocian explained. "But the rain just kept coming and the drawdown structure wasn't able to keep up with all of the water that was coming through from <br />the watershed" <br />Around the holidays, RCWD made the decision to put the stop logs back in the dam, not only because the drawdown was unsuccessful, but also for <br />safety concerns. <br />"At that point solid ice was starting to form on the lake and there was a concern that if we were able to draw the lake down after ice already formed on <br />the lake, then it would just make a messy situation on the edge of the lake with the ice sheet continuing to fall and continuing to break up around the <br />shoreline," he said. <br />http:/twww.presspjbs.com/quad/news/article 4c14bW2 29cb-11e7-ba43-3bdf61121iaftnl 1/2 <br />
