In November 2018, the City addressed damage requiring immediate repair to Conn Dam Spillway (Phase I). The work performed under Phase I involved the repair of edge spalling and crack sealing and was completed in December 2018. The repairs completed as part of Phase I withstood subsequent heavy winter rains, prompting the City to continue with the Phase II evaluation and repairs in 2020. Phase II involved subsurface exploration of the Spillway which was used to guide necessary maintenance related repairs to ensure the Spillway continues to perform as designed and intended.
