VERSION 2007

TITLE: IMPAIRED WATERS RULE STATIONS 

Geodataset Name:       IWR_STATIONS_JUL08
Geodataset Type:       SHAPEFILE
Geodataset Feature:    Point
Feature Count:         60083
GENERAL DESCRIPTION:
A station can only be used for IWR assessment purposes if it represents ambient water quality of surface water and the station can be definitely tagged to one of the 6300 water bodies which we assess. A station will not be in this coverage if it samples wastewater effluent or if it is a rain gauge, or it samples groundwater, etc. Also the station will not be included if it samples a remote piece of water (pond or intermittent stream) that is not part of our water body coverage. These stations are thus the source of data for our IWR assessment that is used in the TMDL process. The majority of our assessment results come from the STORET database, but we also have supplemental data which is not in the STORET database. The majority of this supplemental data comes from Legacy STORET, which has not yet been loaded into STORET and was discontinued by EPA as a viable data storage database in 1998 (Note that the IWR process dictates that the water quality data not be older than 10 years old for most of the assessment procedures, therefore, this older Legacy data is not used for these procedures. However, there are assessment procedures which look at older, historic data to determine baseline conditions, so the older data are still used for a few procedures). Also in the supplemental data is USGS data, SFWMD data (from DBHYDRO), St. Johns River Water Management District data and Florida Dept. of Agriculture and Consumer Services.

USER NOTES:








This data is provided 'as is'. GeoPlan relied on the integrity
of the original data layer's topology













This data is provided 'as is' by GeoPlan and is complete to our
knowledge.













GeoPlan relied on the integrity of the attribute information within
the original data.

























To identify the locations of the stations whose data was used in the IWR Run















The XY data for some of the points are not accurate.  They have been assigned 
to the accurate WBID, if known, regardless of XY data.















This data is provided 'as is' and its vertical positional accuracy
has not been verified by GeoPlan















THE DATA INCLUDED IN FGDL ARE 'AS IS' AND SHOULD NOT BE CONSTRUED
AS LEGALLY BINDING. THE UNIVERSITY OF FLORIDA GEOPLAN CENTER SHALL
NOT BE LIABLE FOR ANY DAMAGES SUFFERED AS A RESULT OF USING,
MODIFYING, CONTRIBUTING OR DISTRIBUTING THE MATERIALS.

A note about data scale: 

Scale is an important factor in data usage.  Certain scale datasets
are not suitable for some project, analysis, or modeling purposes.
Please be sure you are using the best available data. 

1:24000 scale datasets are recommended for projects that are at the
county level.
1:24000 data should NOT be used for high accuracy base mapping such
as property parcel boundaries.
1:100000 scale datasets are recommended for projects that are at the
multi-county or regional level.
1:125000 scale datasets are recommended for projects that are at the
regional or state level or larger.

Vector datasets with no defined scale or accuracy should be
considered suspect. Make sure you are familiar with your data
before using it for projects or analysis. Every effort has been
made to supply the user with data documentation. For additional
information, see the References section and the Data Source Contact
section of this documentation. For more information regarding
scale and accuracy, see our webpage at:

DATA LINEAGE SUMMARY: 








DBF of stations used in IWR Run 30 was displayed using ArcGIS and 
converted to a shapefile.
Process Date: 

Data for a new layer obtained from WRM, data inserted in ArcSDE and 
published in DataMiner and DataCatalog. Metadata updated.
Process Date: 20080611


Dataset updated for IWR Run 32
Process Date: 

Submitted for SDE update.
Process Date: 20080703

GeoPlan downloaded this dataset from the Florida Department of Environmental 
Protection website (http://www.dep.state.fl.us/gis/datadir.htm) in August 2008. 
The data was downloaded in shapefile format and was in the following projection: 
Albers, NAD 83, GRS 80.

- A DESCRIPT field was added based on STATION_NA.
- FGDLAQDATE was added based on date downloaded from source.
- AUTOID field was added.
- Renamed file from IWR_STATIONS to iwr_stations_jul08.
- Upcased all records in the table
