Emergency final costs for Sinnissippi Dam stop logs purchase

Emergency final costs for Sinnissippi Dam stop logs purchase Emergency Final Costs for the completed emergency project of purchasing 4 additional stop logs so they can be placed upstream of Gate 3 of Sinnissippi Dam in Rock Falls, IL. to stop the flow of water through the gate. This will allow the IDNR to maintain the upstream pool elevation at the required elevation until the gate can be examined and a permanent repair is made. Item # 3: ( 570 - 68 ) llinois Department of Natural Resources staff found that one of the inflatable Obermeyer bags present in Gate 3 at the Sinnissippi Dam in Rock Falls would no longer inflate, allowing a section of Gate 3 to be lower than the other gate sections. With this section of gate lower than the other gate sections, it is allowing water to flow uncontrolled through this area. The IDNR is required to maintain a minimum pool elevation of 636.1 upstream of the Sinnissippi Dam to supply water to the Hennepin Canal and to the Rock Falls Hydro-electric plant. Since this section of gate has failed, the IDNR will be unable to properly control the upstream pool elevation, and maintain the minimum required elevation, especially during periods of drought and lower river flows. The uncontrolled flow of water though this section could also put undo stresses and strains on other gate sections which could lead to an even larger failure of the dam. Stop logs are large sections of steel that are placed in the gate bays that can stop the flow of water through the gate section. The IDNR needs to purchase 4 additional stop logs so they can be placed upstream of Gate 3 to stop the flow of water through the gate. This will allow the IDNR to maintain the upstream pool elevation at the required elevation until the gate can be examined and a permanent repair is made. The vendor is fabricating a total of 4 stop logs that will be delivered to the Sinnissippi Dam. Once delivered the stop logs will be placed in the Gate 3 Bay to stop the uncontrolled leakage of water through the gate. llinois Department of Natural Resources staff found that one of the inflatable Obermeyer bags present in Gate 3 at the Sinnissippi Dam in Rock Falls would no longer inflate, allowing a section of Gate 3 to be lower than the other gate sections.
