The lake retention time for a body of water with the volume 2,000 m 3 (71,000 cu ft) and the exit flow of 100 m 3 /h (3,500 cu ft/h) is 20 hours.. Lake retention time (also called the residence time of lake water, or the water age or flushing time) is a calculated quantity expressing the mean time that water (or some dissolved substance) spends in a particular lake.
The residence time of a fluid parcel is the total time that the parcel has spent inside a control volume (e.g.: a chemical reactor, a lake, a human body).The residence time of a set of parcels is quantified in terms of the frequency distribution of the residence time in the set, which is known as residence time distribution (RTD), or in terms of its average, known as mean residence time.
Choke Canyon Reservoir is a reservoir in South Texas, United States. The lake and the dam that creates it are owned by the United States Bureau of Reclamation and managed by the City of Corpus Christi .
Following is a list of dams and reservoirs in Texas.. All major dams are linked below. The National Inventory of Dams defines any "major dam" as being 50 feet (15 m) tall with a storage capacity of at least 5,000 acre-feet (6,200,000 m 3), or of any height with a storage capacity of 25,000 acre-feet (31,000,000 m 3).
The increased residence time of these elements in the lentic system of a reservoir, compared to the lotic system of a river, promotes their sedimentation or elimination [18] which can be up to 40%, 50%, and 60% for nitrogen, phosphorus and silica respectively [19] and this ultimately changes nutrients stoichiometry in the aquatic ecosystem ...
Critics of the Marvin Nichols Reservoir fear the 66,000-acre project could decimate a habitat for little gain. Texas water planners insist this reservoir should be built, but opponents remain unswayed
The comment period runs through Dec. 1.
Lake Lyndon B. Johnson (more commonly referred to as Lake LBJ and originally named Lake Granite Shoals) is a reservoir on the Colorado River in the Texas Hill Country about 45 miles northwest of Austin. The reservoir was formed in 1950 by the construction of Granite Shoals Dam by the Lower Colorado River Authority (LCRA).
