Stony Creek is a small coastal catchment east of Palmerston, covering approximately 9 km². The stream rises on the slopes of Puketapu before flowing through farmland and into Te Awaure Andersons Lagoon, an important coastal wetland and wildlife habitat.

Te Awaure Andersons Lagoon was formed by a natural sand dune barrier that separates the lagoon from the sea, creating a unique wetland environment. The lagoon and surrounding area support a range of native plants and wildlife, while also providing opportunities for recreation including walking, fishing, and duck hunting.

Land use within the catchment is predominantly sheep and beef farming. Due to the small size of the catchment and naturally low stream flows, water quality and habitat can be particularly sensitive to sediment, nutrient losses, and changes in land management.

The catchment is also home to a QEII National Trust covenant and ongoing restoration work, including native planting around Te Awaure Andersons Lagoon. These efforts are helping to enhance biodiversity, strengthen habitat connections, and improve the health of this important wetland system.
