Frequently-anticipated questions:

What does this data set describe?

Title: waterbody (Lakes)
Abstract:
This layer is composed of the lakes on the Siuslaw National Forest. The layer has line and polygon data associated with it. This allows for the retention of line attributes as well as being able to shade in the lakes on maps.
Supplemental_Information:
This layer was updated in 1992. The main portion of the data was obtained from the geometronics service center as 1:24000 quad maps of digital data. The lakes were updated with data that was interpreted from 1:40,000 scale aerial photos with a digital stereoscope by Jim Kiser at Oregon State University. NRIS attributes were added in 2002.

    COM_ID
    A unique identifier of the NHD feature or reach that is never edited. It is assigned across all features by NHD's Feature Object Database. Up to 10-digits, this integer value uniquely identifies the occurrence of each feature. Each value occurs only once throughout the nation. When the feature is deleted, the value for its identifier is retired.

    Up to 10 digit unique whole numbers

    FTYPE
    Stores the common identifier (COM_ID) of the transport or coastline reach that underlies a linear DRAIN feature. This is the foreign key for the relationship that defines which route reach (.ratRCH) the drain (.ratDRAIN) is a member of. For waterbodies, this stores the common identifier (COM_ID) of the waterbody reach that underlies a waterbody. This is the foreign key for the relationship that defines which waterbody region reach (.patRCH) the waterbody region subclass (.patWB) is a member of. Up to 10-digits, this integer value uniquely identifies the occurrence of each feature. Each value occurs only once throughout the nation. When the feature is deleted, the value for its identifier is retired. It is used to relate linear features and their transport or coastline reaches linking the .ratRCH and .ratDRAIN. For waterbodies, it is used as the link between the .patRCH and the .patWB.

    Up to 10 digit unique whole numbers

    FCODE
    A defined entity and its representation. In the NHD, features include naturally occurring and constructed bodies of water, paths through which water flows, and related entities. Features are classified by type, may be described by additional characteristics, and are delineated using standard methods. Feature types and their corresponding definitions provide the basic description of the features. Each type has a name and a definition. The three most frequently encountered feature types and corresponding definitions are 'stream/river', 'lake/pond', and 'canal/ditch'.

    ELEV
    Five digits number that encodes the feature type and combinations of characteristics and values that can be assigned to a type. The first three digits encode the feature type, and the last two digits encode a set of characteristics and values. The general format of the feature code is: FFFCC, in which FFF is the three-digit code for a feature type and CC is the two-digit code for a combination of values for characteristics associated with a feature type. If only the feature type is identified, these last two digits are assigned the value "0". For example, the feature type "dam/weir" has the code "343". There are five combinations of characteristics and values that can be assigned to features of this type. These combinations are assigned the values of "00" through "04". The definition field associated with FCODE uses a single character string to encode one or more characteristics and values for each feature code. The general format of the character string is Characteristic | Value, in which "characteristic" is the name of the characteristic and "value" is the value of the characteristic for the feature code. The vertical line character " | " separates the characteristic and value.

    STAGE
    Elevation above sea level. Elevation of the waterbody, in meters above the vertical datum. In the initial release of the NHD, only canal/ditch, lake/pond, reservoir, and stream/river in the waterbody theme can have elevations. Most of these features do not have a value for elevation, so -9998 (unspecified) is the most common value. For all other NHD feature types, the value for elevation is -9999 (not applicable).
