Delineation

The limit of RESERVOIR is the rim of the constructed basin.

 

Data Extraction

Capture Conditions

 

If RESERVOIR is a sewage treatment pond or a filtration pond,

Or

If RESERVOIR is for water storage and is in an arid region,

Or

If RESERVOIR is not a sewage treatment pond or filtration plant, and is ≥ 0.03" along the shortest axis,

Then capture.

 

Attribute Information

 

If RESERVOIR has a printed elevation on a 1:24,000-scale graphic,

Then Elevation = (Integer Value),

Else Elevation = Unspecified.

 

If Reservoir Type = Water Storage and Cover Status = Covered,

Then Hydrographic Category = Unspecified.

 

If Reservoir Type = Water Storage and Construction Material = Nonearthen, then

Hydrographic Category = Unspecified.

 

If Disposal Type = Tailings Pond,

Then Construction Material = Earthen.

Reservoir Type = Unspecified only in limited update. See Source Interpretation Guidelines,

Revision.

 

If Reservoir Type = Decorative Pool or Swimming Pool,

Then Construction Material = Nonearthen.

 

If Cover Status = Covered,

Then Construction Material = Nonearthen.

 

If Reservoir Type = Aquaculture or Treatment,

Then Construction Material = Unspecified.

 

If Reservoir Type = Evaporator,

Then Construction Material = Unspecified.

 

Source Interpretation Guidelines

 

All

 

Refer to the feature definition to decide how to categorize a given feature instance.

Do not use the proper name of the feature as a guide. Many features that are known

as "Reservoirs" or labeled on the graphic as "Reservoirs" will be captured as

LAKE/PONDS. "Stock Tanks" may be RESERVOIR or LAKE/POND depending on

their form. As a general rule, if a water body has a geometric shape or other

information indicates it is contained by a constructed basin, capture it as

RESERVOIR. If it does not appear to be contained by a constructed basin, capture

it as LAKE/POND.

 

If RESERVOIR is identified as a Minnow Pond, Fish Hatchery, Rearing Pond, Fish

Pond, or similar facility, then capture RESERVOIR with Reservoir Type =

Aquaculture.

 

Fish ponds in natural water bodies are not captured as RESERVOIR. See

ESTUARY, LAKE/POND or SEA/OCEAN.

 

If RESERVOIR is < 0.03" along the shortest axis and is within 0.02" of another

RESERVOIR with the same attribute values, then capture as one RESERVOIR only

if the combined areas are ≥ 0.03" along the shortest axis.

 

If two RESERVOIRS are < 0.005" apart and have the same attribute values, then

capture as two RESERVOIRS with a shared perimeter line.

 

If two RESERVOIRS are < 0.005" apart and do not have the same attribute values,

then displace the perimeter lines equally and capture so that the perimeter lines are

0.005" apart.

 

If RESERVOIR is an oil sump or sludge pit, then collect in the theme Built-Up.

 

If RESERVOIR is divided by wire mesh, screens, or grates, then do not capture the

resulting divisions as separate RESERVOIRS.

 

If RESERVOIR is identified as a sewage disposal pond, then capture RESERVOIR

with Reservoir Type = Treatment and Treatment Type = Sewage Treatment Pond.

 

Graphic

 

If RESERVOIR is symbolized with a black outline,then Construction Material =

Nonearthen.

 

If RESERVOIR is symbolized with a blue or brown outline, then Construction Material = Earthen.

 

If RESERVOIR is < 0.03" along the shortest axis, and shares an outline with another

RESERVOIR with the same attribute values and their combined area is ≥ 0.03"

along the shortest axis, then capture the combined areas as one RESERVOIR.

Revision - Limited

 

Reservoir Type = Unspecified for newly collected RESERVOIRS. Retain Reservoir

Type on existing RESERVOIRS.

 

Elevation = Unspecified for newly collected RESERVOIRS. Retain Elevation on

existing RESERVOIRS.
