As the system is located they will work with the mapping department to ensure our maps are accurate. The mapping department will be printing new map books this winter. • The WTP #7 expansion is now complete. Final payment should be made shortly. • Horwitz Nsi installed a new 10"meter at WTP#6. The installation of the new meter required some wiring and chemical feed changes, which the operators completed. • The Water Department and Streets Department completed the annual drawdown of Lake Orono to perform the inspection of the Elk River Dam. It's important to note that Elk River received 3.5 inches of rain the weekend before the drawdown which resulted in record flows for this time of the year. Attached is a chart showing the flows at 1,670 ft3/s (12,525 gps). The estimated flow over the dam was 1,804 ft3/s (13,527 gps). Despite the high flows, we were able to inspect a majority of the dam. However, due to the Mississippi River being backed up into the Elk River,the inspection of the roller bucket and the downstream riprap was not able to be performed. In previous years it has taken about 24 hours for the lake to refill to its normal level; whereas this year it took about four hours. • The Water Department connected the new 6"water main along Highway 10. This is the first section of water main to be relocated. The second section of water main to be relocated will be completed in accordance with the MnDOT contract. The relocation will take place in the spring of 2018. Page 1 of 2 91
