WEBVTT 00:00.009 --> 00:03.539 Can you come down on each side . My 00:03.539 --> 00:05.706 name is Billy Thompson . I'm a project 00:05.706 --> 00:07.817 manager . We are at , uh , Orwell Dam 00:07.817 --> 00:09.650 in Fergus Falls , Minnesota on a 00:09.650 --> 00:11.817 beautiful September afternoon , and we 00:11.817 --> 00:13.928 are doing repairs , inspections , and 00:13.928 --> 00:15.983 maintenance , uh , on the Orwell Dam 00:15.983 --> 00:18.095 structure . There's 5 main activities 00:18.139 --> 00:20.530 that make up the . Project today . Uh , 00:20.549 --> 00:23.139 the first was the gradual drawdown of 00:23.139 --> 00:26.309 the Orwell Reservoir 14 ft over the 00:26.309 --> 00:29.069 course of 30 days , uh , at half a foot 00:29.069 --> 00:32.380 per day to facilitate the , um , 00:32.389 --> 00:34.278 bulkhead placement , which is the 00:34.278 --> 00:36.520 second activity . So they had to fix 00:36.520 --> 00:38.909 the lifting system on the bulkheads , 00:38.919 --> 00:41.141 do some general pairs in order to place 00:41.141 --> 00:43.750 5 bulkheads that are 25,000 pounds each 00:43.750 --> 00:46.880 to uh close the flow and and allow for 00:46.880 --> 00:49.500 the third activity , which is the gate 00:49.500 --> 00:51.919 chain replacement . And that is being 00:51.970 --> 00:55.250 installed on site today . Uh , the 00:55.250 --> 00:57.659 fourth component of the work is the 00:57.659 --> 00:59.990 heat shield replacement of some damaged 00:59.990 --> 01:02.430 components on the gate , uh , that are 01:02.930 --> 01:05.080 designed to help mitigate or prevent 01:05.080 --> 01:08.050 buildup of ice in the winter colder 01:08.050 --> 01:10.250 months when the dam is elevated from 01:10.529 --> 01:12.696 the water . And then finally , all the 01:12.696 --> 01:14.918 divers are on site here as well . Today 01:14.918 --> 01:16.918 and they are facilitating the floor 01:16.918 --> 01:19.029 drain rehabilitation that's ongoing . 01:19.029 --> 01:21.029 The floor drains on this site are a 01:21.029 --> 01:22.918 critical component for structural 01:22.918 --> 01:25.085 stability . It's impressive to see all 01:25.085 --> 01:27.140 of the different disciplines on site 01:27.140 --> 01:28.918 today to make this happen . The 01:28.918 --> 01:30.640 maintenance and repair crew is 01:30.640 --> 01:32.862 completing all of the work on site with 01:32.862 --> 01:34.696 a 6-man crew . There's 3 primary 01:34.696 --> 01:36.751 reasons why this work is important . 01:36.751 --> 01:39.500 Number one , gate exists primarily for 01:39.500 --> 01:41.980 flood control and for public safety , 01:42.269 --> 01:45.669 so the maintenance , repair , and 01:45.669 --> 01:49.440 ongoing inspections ensure that 01:49.830 --> 01:52.910 this dam will perform as designed for 01:52.910 --> 01:56.069 years to come , and then also inform 01:56.069 --> 01:58.940 future maintenance needs down the road . 01:59.980 --> 02:02.129 Orwell Dam is important for , uh , 02:02.139 --> 02:04.970 water supply , uh , for municipalities , 02:05.099 --> 02:07.300 uh , and agricultural needs , as well 02:07.300 --> 02:09.411 as recreation for hunting , boating , 02:09.411 --> 02:11.522 fishing , and other activities around 02:11.522 --> 02:12.369 the lake itself .
