ASSESSMENT OF EXISTING WATER SUPPLY SYSTEM 3.1 VISITOR NU!1BERS From the visitor information statistics provided by ANPWS (Appendix 1) it .~as estimated that the camping areas would receive 200 campers on a peak day during the tourist season. It was assumed that the peak day would occur in the weekend and that the number of visitors per day on a weekend would be twice that on a week day. This peak day usage rate represents 2% of the yearly rate. The number of campers at Merl 1 on a peak day was estimated at 120 and for Herl 2 at 80. These estimates are based on the assumption that Merl 1 would cater for 1.5 times the campers in Merl 2. The number of visi':ors to Obiri Rock on a peak day ,~as estimated to be 2370 which is 2% of the total visitors to Obiri for 1990. This figure of 2% comes from the proportion of peak day usage to yearly usage at the Merl camping grounds in 1989 and 1990. The maximum number of visitors to Obiri Rock at anyone time was estimated to be 405 and was based on the maximum number of coaches (6) and cars (35) reported at Obiri on a single occasion. 3.2 WATER DEMAND SOURCES The demand for water at the East Alligator District arises from the following sources: 005MJ campers day visitors ranger/staff houses border store and youth hostel fish cleaning facility coutine cleaning
