RCWD <br />anRI(E (REEK WATERSHED DISTRICT <br />FREQUENTLY ASKED QUESTIONS <br />WHAT IS THE PURPOSE OF THE DRAWDOWN? <br />The purpose of the drawdown is to improve the overall water quality in Peltier Lake by allowing near -shore <br />sediments to freeze, dry out, and kill cudyleaf pondweed, as well as reoxygenate and consolidate sediments for <br />native plants. <br />WHEN WILL THE DRAWDOWN BEGIN? <br />The drawdown is tentatively planned to begin after Labor Day weekend. It is likely the drawdown will begin on <br />or around September 19th. <br />WHAT IS THE RATE OF THE DRAWDOWN? <br />The drawdown is expected to occur slowly, at a rate of just under 1 inch per day. <br />HOW FAR WILL THE LAKE BE DRAWN DOWN? <br />The lake will be drawn down approximately 3 feet below the ordinary high water elevation. <br />WHAT IS THE AMOUNT OF LAKE 80TTOM THAT WILL BE EXPOSED AFTER THE <br />DRAWDOWN? <br />Approximately 199 acres of the near -shore lake bottom will be exposed once the drawdown is completed. This <br />represents about 34% of the lake bottom area. Figure 1 shows an estimate of what the drawn down lake <br />footprint will look like. <br />WILL THE ICE BE SAFE DURING THE WINTER? <br />Once the drawdown is completed, the lake will freeze over as normal. The same ice safety precautions apply to <br />the area of the lake near the aeration system. <br />HOW LONG WITH THE DRAWDOWN LAST? <br />The drawdown is anticipated to begin after Labor Day weekend (approximately September 19, 2016). It is <br />expected that the lake will take approximately 51 days to reach its lowest level. The lake will remain at this level <br />until ice out (typically mid-March to mid-April), when the stop logs will be replaced in the dam and the lake will be <br />allowed to fill to its normal water levet. <br />HOW WILL THE DRAWDOWN AFFECT BOAT REMOVAL? <br />The drawdown has been scheduled to begin and take place at the end of the typical recreational boating <br />season (after Labor Day). Although the drawdown rate is low (about 1 inch per day), it is highly likely that the <br />Peltier Lake boat launch will become unusable at some point (i.e. the ramp will not extend far enough into the <br />lake). Some preplanning should be taken by boat owners and lakeshore residents prior to ensure that boat <br />removal is completed prior to the start of the drawdown. <br />HOW LONG WILL THE LAKE TAKE TO REFILL? <br />The lake will very likely refill within a few weeks, dependent upon the amount of snowmelt and the size of spring <br />rainfall events occurring during the refill period. <br />WILL THE DRAWDOWN RESULT IN ANY FLOODING IMPACTS, EITHER DURING THE <br />DRAWDOWN OR DURING THE REFILLING? <br />4 <br />`SVA <br />
