The plan <br />= show the proposed outlet to the Olson Lake Trail culvert and the DNR missed it. The <br />DNR's authority to review this plan is because one wetland (383W) was planned to be <br />filled for road construction and another wetland (477W) was to be altered by expanding It <br />to create the large central wetland, The DNR also has jurisdiction if an outlet is used as the <br />level control structure. <br />The DNR's concerns are whether the pond constructed as shown on the plans and whether <br />the quality of the water reaching Olson Lake can be improved. <br />2, USCOE <br />Even though the COE was not at the meeting they passed on their concerns to the DNR <br />before the meeting, The COE jurisdiction is any time a wetland is altered, The COE's <br />concern is whether the pond was constructed as planned, <br />
