The Narran Lake Nature Reserve includes an inland freshwater wetland formed by the termination of the Narran River. The wetlands have at times provided a habitat for significant bird breeding events and they provide a refuge for a multitude of bird species in a changed landscape surrounding the park dominated by grazing and agriculture. The area was a common meeting place for Aboriginal people for thousands of years and this is reflected in the current joint management of the park between NPWS and members from the local Aboriginal community. The reserve is rich in indigenous artefacts and places of cultural significance including the most extensive shell middens in North West New South Wales.
