Course and features
The Rock Flat Creek (technically a river) rises below One Tree Hill, on the lower slopes of the Snowy Mountains, part of the Great Dividing Range. The creek flows generally north by west before reaching its confluence with the Cooma Creek just upstream from that creek's confluence to form the Numeralla River (itself a tributary of the Murrumbidgee River), north of the town of Cooma. The creek descends 336 metres (1,102 ft) over its 41-kilometre (25 mi) course.
There is a mineral spring that comes to the surface on the bank of Rock Flat Creek about 16km south-east of Cooma. The spring water issues from near the base of a small rocky mount composed of highly inclined beds of quartzite and the surface of the flat in the vicinity of the spring is tufaceous limestone that has been deposited there by the spring water. The flow rate of the spring is about 245-litres per hour. The spring water has a pleasant taste and is carbonated.
