TITLE: PHOSPHORUS RESTRICTIVE BASINS
Geodataset Name: PHSBAS Geodataset Type: SHAPEFILE Geodataset Feature: POLYGONGENERAL DESCRIPTION:
This dataset contains watersheds that have water quality characterized by elevated phosphorus levels and are restricted to the amount of phosphorus that can be imported into the watersheds. Phosphorus can only be applied at agronomic rates. |

The dataset consists of 4 watersheds and some specific counties that have high levels of phosphorus
in the surface water. As a result, these watersheds have restrictions on the amount of phosphorus
that can be imported into the watersheds and applied to the land. The 4 watersheds are Lake
Okeechobee, Lake Apopka, the Green Swamp and the Everglades Protection Area (EPA), and the
counties include all of Glades, Hendry and Okeechobee. |
A note concerning data scale: Scale is an important factor in data usage. Certain scale datasetsare not suitable for some project, analysis, or modelling 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. 1:250000 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 analyses. Every effort has been made to supply the user with data documentation. For additional information, see the References sectionand the Data Source Contact section of this documentation.

The Phosphorus Restrictive Basins was created from the drainage basins coverage (basin-24 (area)). The watersheds were created by unioning the appropriate drainage basins in the basin-24 cover. Some additional modifications (subtracting and splitting polygons) were made to create the Green Swamp boundary. The watershed boundaries for Lake Apopka and Lake Okeechobee area based on the boundaries established by the Surface Water Improvement and Management (SWIM) Program. The boundary for the Everglades Protection Area (EPA) is based on the Everglades Forever Act (EFA). The boundary used for the Green Swamp is describe in chapter 22F-5, Florida Administrative Code.
