Specifications include, but are not limited to: replace the outlet structure that regulates the lake level of three interconnected lakes: Tippecanoe Lake, Oswego Lake, and James Lake. The existing outlet structure was built in 1964 and is comprised of 10 manually-operated gates and overflow weirs on a concrete foundation. The two-foot deep foundation rests on sand and has no cutoff to prevent movement. As a result, the structure incurred damage in the early 1990s due to undermining of the foundation. Riprap was placed in the scour hole as a temporary repair. In addition to concerns regarding the structure’s foundation, the steel gates are weathered, some gates are no operational during winter months, and the overflow weirs are not appropriately sized. The gates and appurtenances will be removed and a new outlet structure constructed upstream of the existing structure.
