PEL (Pellicer Creek)
Location: latitude 29°39’04.662”, longitude 81°17’12.812”, GPS datum—WGS-1984 Station PEL is located on Pellicer Creek at U.S. Highway 1.
Point sources: There are no wastewater treatment facilities within a five-mile radius or within the drainage basin of this water quality site.
Pellicer Creek begins in the wetlands of southern St. Johns County and runs east where it forms part of the border between St. Johns and Flagler counties in east-central Florida. The creek empties into the coastal marine environment of Pellicer Flats and the Matanzas River on the east coast. The sampling site is located where Pellicer Creek crosses U.S. Highway 1, about 15 miles south of the city of St. Augustine, Fla.
Pellicer Creek is still tidal in the area of the sampling site and is influenced by the amount of rainfall that occurs as to how saline the waters are. The vegetation also contains species like those found in a coastal marine environment. There is commercial and residential development to the north and south of the creek, but to the east lies the Pellicer Creek Conservation Area, covering more than 3,800 acres. The Princess Place Preserve is within the conservation area and it is managed by Flagler County. There are many opportunities for outhoors enthusiasts to enjoy, such as camping, canoeing, hiking, fishing, and more.
All of the maps and charts shown below were created using a customized GIS data summary tool, with the watershed generated by Arc Hydro for this monitoring station. More information about Arc Hydro can be found by going to the Technical background page. From that page, a description of the customized GIS data summary tool can be accessed.
Spatial data summaries
Population data is collected by the Census Bureau every 10 years and is used to show the distribution of population in a number of ways. Population density has a direct impact on land use, which effects water quality in areas around or near water bodies. This map displays the 2000 population density per square kilometer within this surface water catchment. The legend shows the area for each class in square kilometers and the percentage of area in descending order. More complete metadata can be found by clicking on the metadata link for the 2000 population density.
Land use, which is usually derived from aerial photography by photo interpreters, shows the distribution of land and how it is used. Land use affects the water quality of water bodies through water runoff within a surface water catchment. This map displays the distribution of eight categories of general land use within this surface water catchment. The legend shows the area for each category in square kilometers and the percentage of area in descending order. More complete metadata can be found by clicking on the metadata link for general land use 2000.
The geology of the state of Florida was delineated by the Florida Geological Survey. Water quality is impacted by the underlying geology of streams and lakes. This map displays the underlying geological formations within this surface water catchment. The legend shows the area for each type of formation in square kilometers and the percentage of area in descending order. More complete metadata can be found by clicking on the metadata link for geology.
Physiography describes the earth’s exterior physical features. These are divided into general groups and then subgroups containing features such as uplands, hills, ridges, plains, valleys, karst, etc. Water quality is affected through water runoff by physiography. This map displays the more detailed physiographic subdistricts within this surface water catchment. The legend shows the area for each subdistrict in square kilometers and the percentage of area in descending order. More complete metadata can be found by clicking on the metadata link for physiographic divisions.
Rainfall data comes from radar imaging as well as rainfall gauge surveys. Rainfall affects water quality through runoff within the surface water drainage basins. This map displays the total daily rainfall in inches for each pixel for 2004 within each surface water catchment. The legend shows the area for each rainfall range in square kilometers and the percentage of area in descending order. More complete metadata can be found by clicking on the metadata link for 2004 rainfall.
The St. Johns River Water Management District (SJRWMD) purchases lands that are in environmentally sensitive areas to protect the water resources on, beneath or adjoining the property. Water quality is affected in water bodies adjacent to these protected lands. This map displays the lands owned, jointly owned, being considered for purchase, or lands through which SJRWMD has an easement. The legend shows the area of these lands in acres and the percentage of area in descending order. More complete metadata can be found by clicking on the metadata link for SJRWMD and public lands.
Soils drainage characteristics can also impact surface water runoff, a source of nonpoint pollution for adjacent water bodies, which effects water quality. This map displays water bodies and soil drainage characteristics. The legend shows the area of these soils in square kilometers and the percentage of area in descending order. More complete metadata can be found by clicking on the metadata link for soils drainage.
Land elevation influences rainfall runoff, which effects the surface water quality, as water moves through the landscape to the rivers, streams, and lakes. This map with accompanying legend displays the maximum (MAX), minimum (MIN), range, standard deviation (STD) and mean of 5-foot elevations within the surface water drainage area (watershed). More complete metadata can be found by clicking on the metadata link for 5-foot elevation-DEM (Digital Elevation Model).
In some areas of SJRWMD, the Floridan aquifer is at or near land surface and is vulnerable to pollutants that threaten our drinking water supply. It is especially important to preserve surface water quality in these areas. This map displays recharge to the Floridan aquifer in inches per year (in/yr) within this surface water drainage catchment. Discharge, where the potentiometric surface is greater than the land surface elevation, is also shown. The area for each class is shown in square kilometers and the percentage of area in descending order. More complete metadata can be found by clicking on the metadata link for recharge 1995.
The map below contains selected features from the St. Johns River Water Management District (SJRWMD) Arc Hydro geodatabase. The introduction of the SJRWMD Arc Hydro geodatabase made the creation of these fact pages possible, by providing improved geographic information system (GIS) data that has been combined into a GIS network. This hydrologically based network does for water resources what the commonly used mapping websites (such as MapBlast, MapQuest and GoogleMaps) have done for travel planning, except that instead of interstates, highways and roads, this hydrologic network shows streams, rivers, lakes and wetlands. Similar to transportation mapping sites, information about water resources has been related, or linked, to the GIS network and can be easily accessed. The legend to the right of the map includes the Arc Hydro network, Arc Hydro Polygon Feature Classes and HydroPoints. The features included in the Arc Hydro Network exist to establish relationships based on surface water flow. The lines (HydroEdges) may represent streams or rivers, which are commonly displayed as lines on maps. The lines may also represent, in a “shorthand” way, the concept of surface water flow through a lake or a wetland, which are not routinely displayed as lines. The features in the Arc Hydro Polygon Feature Classes and HydroPoints represent some of the water resources information that has been linked to the Arc Hydro GIS network. HDS in the map legend below refers to the District’s Water Resource Information program and NWIS refers to the National Water Information System, which is part of the United States Geological Survey (USGS). See Technical Background for a more detailed explanation of the SJRWMD Arc Hydro technology and its features.

Pellicer Creek drains Fish Swamp and Pringle Swamp to the Matanzas River. It is sampled every other month, at U.S. Highway 1, as part of the ambient monitoring program. The river is about 2.6 meters deep at the sample site and has a typical temperature range. Major ion concentrations vary, but result in moderately hard water. The median dissolved oxygen concentration is less than typically found in District streams. The water has fair buffering capacity and a neutral pH. When compared to other stream sites in the District, total organic carbon concentrations and Secchi depth are typical, although color is elevated. Total phosphorus concentrations are typical, while total suspended solids, turbidity, total nitrogen, and chlorophyll concentrations are lower than typically found. The river has fair water quality at the sampling site, according to the water quality index.
