THE MOTION CARRIED 5-0. 4. Lake Orono Study and Recommendation Building and Zoning Administrator Steve Rohlf presented the Lake Orono Sedimentation and Water Qualify Study. He explained that the Lake Orono Sedimentation Task Force has been meeting since May of 1995 to study the lake. Steve Rohlf reported that the water qualify has been studied. He indicated that the study found that there were no significant levels of contaminants in the lake, however, there were high levels of phosphorus. He stated that the Committee recommends reducing the manmade sources of phosphorus in both the Elk River and Lake Orono. Steve Rohlf reported that significant levels of fecal coliform have been found in the lake in July and August. The Committee recommends monitoring the lake for fecal coliform weekly throughout the swimming season. He further reported that it is believed that the fecal coliform is of animal origin which is considered less of a health threat than those from human origin. Steve Rohlf reported on the sedimentation stating that the suspended sediment is not considered a major issue as more suspended sediment is leaving the lake than entering. However, bedload is a heavier material and is deposited in the lake. He indicated that sources of erosion upstream from the lake should be eliminated as much as possible. Steve explained that if bedload is not removed, the lake will eventually fill and become a river once again. Steve Rohlf stated that the timing of the project is an issue because of the availability of land near the lake for depositing the material that must be removed from the lake. Steve explained that if the material has to be trucked away from the immediate lake area, the cost would increase significantly. Steve Rohlf proceeded to identify the areas the Task Force has recommended for correction. He indicated that the Task Force is recommending the mid range project which will cost approximately $750,000.
