Wyaralong Dam Turtle Monitoring, Seqwater

Share on:

GHD is playing a key role in helping Seqwater manage and monitor potential impacts of dam construction and operation on four species of freshwater turtle population. Our team designed and implemented the monitoring program to comply with legislative requirements, facilitate the identification of potential impacts and the implementation of adaptive management.

As part of this project, monitoring of the turtle population was undertaken above and below the dam wall every six months for the duration of the construction of the dam, and for the first five years of dam operation. Freshwater turtle populations were sampled using cathedral traps with individuals captured identified to species level and life history parameters recorded. Captured turtles were tagged with monel foot tag and released at the site of capture to assess turtle movement behavior through mark recapture. Annual monitoring of potential turtle nesting habitat was undertaken during the peak turtle nesting season over the five years of operation. Bank margins within five survey areas were assessed for nesting habitat suitability and systematically searched for both direct and indirect evidence of turtle nesting. Turtle monitoring program reporting was conducted following each survey event for compliance with Project approval conditions.
