Access constraints: Discretionary, contains no sensitive information - generally considered releasable.
Use constraints:
This data should be used in conjunction with the Lake Havasu Field Office RMP of 2007.  This data should not be used at a scale larger than 1:100,000.  The data and corresponding attributes are only as accurate as the source maps from which they were obtained, and may vary depending on the data and method of acquisition.

This data is suitable for regional planning, management decision support at intermediate scales (i.e. 1:100,000 or smaller), and cartographic purposes.  The data is not suitable for analysis at scales larger than 1:100,000.

If the Receiving Agency (RA) has modified the data in any way, they are obligated to describe the types of modifications they have performed on hardcopy maps utilizing the data.  RA specifically agrees not to misrepresent LHFO datasets or to imply that any changes made were approved by BLM LHFO.

No warranty is made by the BLM for use of the data for purposes not intended by BLM.  This information may be updated without notification.

Data Quality Information:


Attribute accuracy:
Attribute accuracy report:
Feature attributes were taken from source material.  Code assignments are believed to be representative of the source document.

Quantitative attribute accuracy assessment:
Attribute accuracy value: 100%
Attribute accuracy explanation:
The attributes only contain calculated acres for the area.

Logical consistency report:
Data was reviewed for correct topological structure.  Duplicate lines have been removed.

Completeness report:
The dataset is considered complete for the Lake Havasu/Colorado River Regional Management Area in the Lake Havasu Field Office RMP (2007).

Positional accuracy:
Horizontal positional accuracy:
Horizontal positional accuracy report:
Overall horizontal accuracy for this data is not greater than national mapping accuracy standards (NMAS) for USGS source maps.  Snapping and coordinate shift tolerances were maintained at 0.01 meters or less through editing.  Horizontal positional accuracy for the digital data set was tested by visual comparison of the source data with hard copy verification plots.

Lineage:
Process step:
Process description:
The Lake Havasu SRMA was selected from SRMA_ALL_ZONES.shp and used to create the LakeHavasuSRMA.shp which was used as the Lake Havasu Regional Mangement Area in the Draft Lake Havasu RMP (2005).

Process step:
Process description:
Lake Havasu and the Colorado River up to Davis Dam were selected from hydro_p.  This area was buffered by 50 feet and merged with adjacent BLM administered lands, Havasu NWR, Lake Meade NRA, and Beale Slough resulting in Lake_Buffer2.shp.  The shapefile was then erased with SRMA_ALL2a.shp and dissolved to produce Lake_Buffer2_Erase_Dissolve.shp.  The shapefile was then unioned with LakeHavasuSRMA.shp and dissolved to produce LHCRRMA.shp for the LHFO PRMP/FEIS.
