Executive Summary <br />•The Elk River continues to be the main driver of the conditions in the lake <br />and recent studies indicate the Elk River transports ~200,000 acre-feet of <br />water downstream each year <br />•Further, the Elk carries upwards of 40,000 - 60,000 lbs of phosphorus and <br />as much as 3 - 7 million lbs of sediment annually <br />•Sediment deposits are greater where water velocity slows, such as where <br />the Elk flows into Lake Orono (Upper Lake Orono) and beyond the “pinch <br />points” that separate the basins of the lake <br />•These areas were dredged in 1998, and a model predicted that at the <br />estimated rate of deposit the areas would be refilled in roughly 20 years <br />(based on LOWQC observations…this prediction is accurate)
