Pores (the spaces that exist between soil particles) provide for the passage and/or retention of gasses and moisture within the soil profile.The soil's ability to retain water is strongly related to particle size; water molecules hold more tightly to the fine particles of a clay soil than to coarser particles of a sandy soil, so clays generally retain more water.

The 456 billion gallons (1.4 million acre feet) of water is lifted by up to 2,900 feet by 14 pumps using 2.5 million MWh of electricity each year [285 MW], making CAP the largest power user in Arizona. Lake Pleasant is used as a buffer. [3] [4] The canal loses approximately 16,000 acre-feet (5.2 billion gallons) of water each year to evaporation.
