The capacity of a reservoir's conservation pool; if the reservoir is
shared with another state or country then conservation capacity refers
only to the portion that belongs to Texas.
Conservation pool refers to water in a reservoir that lies above the
dead pool and below the normal maximum operating level. For reservoirs
with a flood storage function, the normal maximum operating level also
corresponds to the bottom of the flood pool. When a reservoir's
conservation pool is full, the reservoir is considered full.
The amount of water present within a reservoir's conservation pool; if
the reservoir is shared with another state or country then conservation
storage refers only to the portion that belongs to Texas.
Dead pool refers to water in a reservoir that cannot be drained by
gravity through a dam's outlet works. Water that is in the dead pool is
not considered part of conservation pool.
A table that relates water surface elevations with volumes and surface
areas for a reservoir. These relationships are obtained from either from
original design documents or from a hydrographic survey of the
reservoir. A single reservoir may have multiple tables that reflect
changes in reservoir conditions due to processes like sedimentation.
Flood pool refers to water that lies above the conservation pool in
reservoirs with flood storage function. A reservoir's flood pool is used
to regulate floodwaters. Some reservoirs have seasonally-varying flood
Height Above Conservation Pool
The vertical distance between a reservoir's water surface elevation and
the top of the conservation pool. Negative numbers indicate how far
below 'full' the reservoir is, while positive numbers indicate how far
above the top of the conservation pool the water surface is.
The ratio of conservation storage to conservation capacity expressed as
The total amount of water that a reservoir can safely hold. It is the
sum of dead pool, conservation pool and flood pool.
The amount of water present in a reservoir.
Part of reservoir capacity that is allocated for storage of sediment
that is expected to be deposited over a certain period of time. Sediment
reserve and dead pool storage are not mutually exclusive.
The area of the top surface of a reservoir's body of water.
Water Surface Elevation
The elevation of the top surface of a reservoir's body of water.
