The evapotranspiration of a crop is the total amount of soil water used for transpiration by the plants and evaporation from the surrounding soil surface. Pueblo Reservoir opened in 1975, and has been a wonderful amenity for all of Southeastern Colorado. Water falling as rain upstream of the reservoir, together with any groundwater emerging as springs, is stored in the reservoir. (Cachuma water storage is based on Dec 2013 capacity … Rainfall and irrigation water entering the soil tends to replenish the soil storage reservoir and extend its ability to support plant life. By 1929, further storage capacity was required. The minimum release is then expressed as a constraint in an optimization model that determines the optimal reservoir capacity and a new operating rule curve to maximize reservoir net benefit. The amount of water that would cover one acre of land one foot deep. Not only is it the terminal storage for Fryingpan-Arkansas Project water, but it provides a quality recreation experience for boaters from all over the country. Surface storage is a costly way to expand water supplies in part because most favorable reservoir locations already have large dams. Construction began September 1995 and the reservoir was completed in March 2000 and doubled the region's water storage capacity. The amount of water used by the plants for transpiration can, like evaporation, be expressed in millimetres of water per day (mm/day). The following two methods are generally used for determining the capacity of a storage reservoir: 1. Analytical Method: In this method an analysis of demand and inflow of water per month of the year is made. The following data are required: These waters drive the Glen Can- [1] Water storage is an important way to cope with temporal variation in water supply and demand. The water from the reservoir also serves the purpose of irrigation. MWL: Maximum water level . For example, expansion of Shasta Reservoir would cost $1,700 per acre-foot of water storage gained and for an additional 634,000 acre-feet of new storage capacity the estimated cost would be $1.1 billion. Stored water may be piped by gravity for use as drinking water, to generate hydro-electricityor to maintain river flows to support downstream uses. This graph shows the average daily water consumption of residential households (expressed in litres per person per day) in the Orange City Council area. This is the case 1) for relatively large drainage area basins where reservoir storage, expressed as a spatial average, is small (e.g., Mississippi and Nile); 2) when reservoir variations are small because of small installed storage capacity relative to the annual flow (e.g., Mekong); or 3) when both occur (e.g., Amazon and Lena).
