CHA’s Otisco Lake Dam Rehabilitation Project recently received the New York State American Public Works Association (NYS APWA) Structures Project of the Year and the Central New York American Society of Civil Engineers Honorable Mention Award.
Located in Onondaga County, this historic dam was built in 1909 and is part of the Onondaga County Water Authority (OCWA) system which provides drinkable water to hundreds of thousands of residents throughout Central New York. Over the years, the dam has proven resilient to catastrophic and unpredictable Central New York weather. However, given the age and importance of the structure, OCWA, upon CHA’s recommendation, decided to strengthen the dam with the understanding that the design life of many of the original stabilization components had been exceeded.
The project involved installation and load testing of post-tensioned anchors through the concrete gravity sections of the dam, resealing the flood spillway overlay panel joints, and performing various concrete and mortar repairs. This dam rehabilitation project provided improvements to the structure of the Otisco Lake Dam that will safeguard against future extreme flood events for years to come.
CHA’s Otisco Lake Dam Rehabilitation project had already been awarded the 2016 Central New York American Public Works Association (APWA) Structures Project of the Year Award. Congratulations, to Brian Bidonde PE, Seth Erlich PE, Jenn Everleth PE, Tami Jameson PE, and Mike Quinn PE, on responsibly improving the world we live in!
