Project overview
The Crow Dam Spillway Project consisted of two phases: Phase 1 of construction (Area 2) consisted of replacement of the badly deteriorated existing chute and stilling basin with a new chute, a flip bucket, and armored apron to dissipate the energy prior to discharging into Lower Crow Creek. The Phase 2 (Area 3) consisted of the replacement of the existing side-channel inlet structure and tunnel with a piano key weir spillway crest structure, sloped trough, channel crossing beneath Crow Dam Road that will tie into the new structures constructed in Area 2, and installation of a bridge at the Crow Dam Road crossing.
