This graph shows 50 years for gage flows for the South Platte River as it leaves the state of Colorado. This represents water that could be available for in-basin re-use. Further work needs to be done to quantify the actual amount that could be used at a specific point, and how much water is owed to downstream users under compact obligations, but at lease we know that there is a sizeable amount of water that is in the river, and could be available.
