B24 WATER STORAGE AND CANALIZATION. 
445 miles, the Barwon 510 miles, the Castlereagh 365 miles, the 
M‘Intyre 350 miles, the Macquarie 750 miles, and the Warrego 
100 miles in length, are all tributaries of the Darling, which itself 
flows into the Murray 300 miles in a direct line below Albury. 
The Murray, with its various feeders and tributaries, draining a
