Goodga River is located 20 kilometres east of Albany, with the majority of the catchment being located in the Two Peoples Bay Nature Reserve. The River is only 10 kilometres long and flows into Moates Lake and then onto Gardner Lake before eventually flowing into Two Peoples Bay.

The average annual rainfall across the catchment is 1100mm and the majority of the rainfall occurs over the winter months. The Goodga Weir is located on the River and has measured stream flow since 1964. In 2004 a fishway was constructed so that fish could migrate upstream of the weir.

The Goodga River catchment typically consists of low forest of Sheoak and Albany Blackbutt. Approximately 30% of the catchment has been cleared for agriculture.

The Goodga River was sampled in August 2007.

Spotted Minnow, also known as Western Trout Minnow, were recorded at both sites. This species is list as critically endangered under the Environment Protection and Biodiversity (EPBC) Act and is only found in the Albany region.

Shrimp and fresh water crayfish species Cherax preissii were also found at both sites.

Gobie and Common Jollytail were recorded at GOO02.

Pictures of these can be viewed in the gallery.

Both sites were determined to have A grade foreshore condition and were considered to be pristine.

Water samples were taken once from each site so while they help describe the water quality at the time of sampling they can not be used to explain the overall condition of the river for the rest of the time.

Goodga is a fresh water system (1.3 ms/cm) with a neutral pH (6.6 - 6.8 pH).

GOO01 recorded very high levels of turbidity (31.4ntu) and GOO02 recorded a high level (14.5ntu).

The River recorded high levels of total phosphorus (83 - 150 μg/mL). GOO01 recorded high levels of total nitrogen and GOO02 recorded moderate levels.
