You can frack with very little water depending on the reservoir characteristics. You can also tap saline watet from underground and move it instead of using fresh. Not that I think it is a bad thing to use fresh water, the volumes are pretty small compared to river flows. The average in the USA is 9.6 million gallons of water per well. 36,339.95m³. The Yukon River at Whitehorse (far away, but a source of comparison people may be able to relate to) has flows of an average 243 m³/second, 646 m³/second (highest),32.6 m³/second (lowest).

Examples of average reported water usage per well include:
Marcellus Shale, Pennsylvania, 4.5 million gallons (Risser, 2012, USGS Public Lecture, "Shale gas, Hydraulic Fracturing, and Induced Earthquakes")
Wattenburg Sandstone, Colorado, 2.7 million gallons (Goodwin and others, 2012, Oil and Gas Journal)
Barnett Shale, Texas, 2.8 million gallons (Nicot and Scanlon, 2012, Environmental Science and Technology)
Eagle Ford Shale, Texas, 4.3 million gallons (Nicot and Scanlon, 2012, Environmental Science and Technology)
Haynesville Shale, Texas, 5.7 million gallons (Nicot and Scanlon, 2012, Environmental Science and Technology)
Bakken Formation, North Dakota, 1.5 million gallons (S. Haines, 2012, USGS personal communication)
Horn River Shale, British Columbia, Canada, 15.8 million gallons (Horn River Basin Producers Group, 2010).
