TLDJARABADA This site is on Jay Creek, the Iwupataka co~"unity, on about 3 kilometres upstream Aboriginal land. from If the flood mitigation aspect is not considered, this site on Jay Creek represents the most attractive and probably the only reasonably alternative to the Telegraph Station site.

(a) Hvdrology The catc~~ent area is 223 sauare kilometres, while the lake size itself '.;Quld be up to 64 hectares in area. French (1973) found that the lake would be filled once a year on average, and several times in every wet year. Comparison with recent ~vorkings for tie Telegraph Station site, based on considerably more data, lead to the conclusion that the lake would probably be at least 40 hectares in area for at least 90% of the time. l.~ " ~, (b) Recreation Potential lake would be inferior to the Telegraph Station site as area "lOuld be some 30% smaller.
