Rock Flat Creek is a watercourse that is part of the Murrumbidgee catchment within the Murray–Darling basin. It is located in the Monaro region of New South Wales, Australia.
Course and features
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 its tributary, Cooma Creek, and then flows into 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.
The Monaro Highway crosses the creek near the locality of Milton Park.
Mineral spring
Near the Monaro Highway crossing, there is a mineral spring that comes to the surface, on the bank of Rock Flat Creek, about 16 km 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.
An analysis of the spring water, c.1900, in units of grains per imperial gallon, revealed its mineral content as follows
| Chemical compound | Grains per
gallon |
Milligrams
per litre |
|---|---|---|
| Sodium Chloride | 2.51 | 35.78 |
| Calcium Carbonate | 56.08 | 799.35 |
| Sodium Carbonate | 70.50 | 1004.89 |
| Lithium Carbonate | 2.50 | 35.63 |
| Magnesium Carbonate | 24.61 | 350.78 |
| Silica | 1.00 | 14.25 |
