System Limitations

Aurora's current water rights portfolio and available infrastructure can adequately serve the
City's water supply needs under average and wet year conditions and under drier conditions of
shorter durations and severity than were experienced in the years 2002 through 2006. During
those severe drought conditions, the sharply reduced productivity of the available water rights
portfolio was supplemented by drought response programs that reduced demands, short-term
leases of agricultural water and other water sources and deliveries from reservoir releases.

These recent drought conditions are, however, not as severe as those seen along the Front Range
during the 1954-56 drought and that period is used by Aurora Water as well as other major
municipal water providers in the areas to assess the firm yield of their water systems. Under
those 1950s water supply conditions and with the current water rights portfolio, it is possible for
the City to deliver an average annual supply of 53,000 acre-feet per year of water to its
customers. This yield can be sustained for a three year period but does draw the reservoirs below
