As such it has cool clear water, permanent inflow and outflow a.n.d is deep with a rocky and sandy bottom. The water quality is very good and is consistently so, with only slight changes in conductivity pH and some ions with the first large rains. ARNHEM BORDER SITE - This site contains water 9-10 months of the year, and flows 8-9 months. Water quality is generally good, consistent with continual flushing. Some fluctuation of pH is observed followed by fluctuation in heavy metal concentration. DOWNSTREA.1'1 JABIRU (RANGER) - This site has water present approximately 7 months of the year, but normally only flows 5-6 months of the year. Little variation is observed in the water quality during the period of flow, which is consistent with continuous flushing. MUDGINBERRI BILLABONG - This is similar to Island Billabong, although somewhat sandier in nature. It is permanent, recharged from aquifers and shows little change throughout the year. Its only eccentricities may be those derived from the rural use on Mudginberri Station, including organic carbon and nutrient rises in mid dry season. BUFFALO BILLABONG - This is a stream billabong similar to Mudginberri Billabong which is permanent, deep and sandy and has seepage from surrounding aquifers. Too little record is available to ascertain overall water quality, however it appears good, with only slight seasonal fluctuations. ISLAND BILLABONG - This is the largest of the billabongs ~n the Mudginberri Corridor, is permanent and classified by Walker and Tyler (l) as a channel billabong. The billabong is deep with steep sides, and seepage from surrounding aquifers is suspected. The water quality remains remarkably constant throughout the year wi~~ only a small increase in conductivity towards the end of the dry season. pH reductions are evident with the first flush and some increases in organic carbon are evident towards t~e end of the dry season. This billabong is considered to be at the "headwaters" of the Magela flood plain. - . -~ :-:: :<'"!1::>: I I I I I I I I I I I I I I I I I I I I
