Coramup Creek and its surrounding catchment is one of four surface water catchments collectively known as the 'Lake Warden Catchment' which supports a system of wetlands which are recognised as wetlands of international importance under the RAMSAR convention.

The Bandy and Coramup Creeks were sampled on the 13th of September 2006.

Two different types of fish were found, the Gobi and Spotted Minnow. Shrimps were also found along with Marron and the introduced Yabby. Pictures of these can be viewed in the gallery.

The condition of the vegetation bordering the river at the sites sampled varied from degraded to soil exposed. All sites had weed infestation with the sites on the Coramup both weed infested and erosion evident.

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.

The temperature of the water at the sites ranged from 13.76 to 16.1°C.

Salinity was less in the sites lower in the system with the highest salinity recorded at BAN02 with 34.45ppt (similar to seawater) and the lowest at COR01 with 10.84ppt.

All the sites had neutral to basic water with pH ranging from 7.06 to 8.03.

Total phosphorus recorded in the water at each site ranged from 59 to 35 µg/L with COR02 having the highest level and BAN01 the lowest. For total nitrogen COR02 again had the highest level at 1600 µg/L and COR01 had the lowest at 650 µg/L.
