Glenreagh Flood Study (Extension of Orara Flood Study)

The Orara River and Bucca Bucca Creek catchments are located to the west of Coffs Harbour on the NSW Mid North Coast. Both creeks drain to the Clarence River at Grafton. The creeks rise in the south and flow generally in a north westerly direction, through the villages of Karangi, Coramba, Nana Glen and Glenreagh. The main road, Orara Way, is located along the left bank of the Orara River and the Grafton to Coffs Harbour railway line, along the right bank.

This study focussed on the village of Glenreagh, located in the Orara River and Bucca Bucca Creek (Bucca Creek) catchments. These catchments lie to the west of Coffs Harbour forming part of the Clarence River catchment. The two water courses rise in the south and flow generally in a north westerly direction. The catchments are primarily rural, with villages of Karangi, Coramba, Nana Glen and Glenreagh located in the catchment, upstream of Grafton.

The primary objective of this study was to define the main-stream flood behaviour at Glenreagh under historical conditions and design flood behaviour under existing and future climate conditions in the study area. The study produced information on flood levels, depths, velocities, flows, hydraulic categories, and provisional hazard categories for a full range of design and historical flood events. To achieve this objective, the study collected, compiled and reviewed all available relevant data (including survey, aerial photography and satellite imagery).
