Eleven reservoirs have a storage capacity greater than or equal to 1,000,000 acre-feet (1.2 km 3); all of these except one are in or on drainages that feed into the Central Valley. The largest single reservoir in California is Shasta Lake, with a full volume of more than 4,552,000 acre-feet (5.615 km 3). Map all coordinates using OpenStreetMap.

A taxonomy is an arrangement in a systematic manner; the USDA soil taxonomy has six levels of classification. They are, from most general to specific: order, suborder, great group, subgroup, family and series. Soil properties that can be measured quantitatively are used in this classification system – they include: depth, moisture ...
Topsoil is composed of mineral particles and organic matter and usually extends to a depth of 5-10 inches (13–25 cm). Together these make a substrate capable of holding water and air which encourages biological activity. There are generally a high concentration of roots in topsoil since this is where plants obtain most of their vital nutrients.
