Map Description: |
The Wreck Pond Watershed has been
a "hot-button" issue in the state of New Jersey for many years. Health officials have declared
numerous swimming bans adjacent to the Wreck Pond watershed drainage point.
The Wreck Pond Technical Advisory Committee (TAC) are members from state and local agencies
that have collaborated on finding solutions for the water resource issues of the Wreck Pond
watershed. Members of the (TAC) include Chairman Tom Kellers of the Monmouth County Planning
Board, John Showler and Hunter Birkhead (NJ Department of Agriculture) Steve Jacobus and
Elizabeth Dragon (NJDEP, Division of Watershed Management) Michael Hill (Freehold Soil
Conservation District), John Brockwell and Dejung Gewissler (Monmouth County Office of GIS,
MCOOGIS).
The task of the MCOOGIS is to coordinate spatial data throughout the TAC and make continued
updates to the Wreck Pond watershed model using Arc Hydro. The implementation of Arc Hydro
assists the TAC by modeling the watershed. The GIS objective is for Arc Hydro to assist our
H & H Engineers in efforts to place BMP's (Best Management Practice) in the Wreck Pond
watershed. The technical aspect of our map is the use of the Arc Hydro toolbar to digitally
depict the flow of water within the watershed. Our first process is to generate a Digital
Elevation Model (DEM). The DEM is generated using 2’ foot contours created from County of
Monmouth's existing planimetric data. Once the DEM is in place, MCOOGIS uses Arc Hydro to
create several other grids. The grids then generate a geodatabase containing features classes
of basins, stream channels and catchment boundaries.
Map Created with an HP 5000ps 42” plotter on semi-gloss paper. GIS tools include ArcGIS
ArcINFO 8.3 & 9.0. with the ESRI Spatial Analyst extension. Two-dimensional flyovers created
using ArcGIS ArcGlobe.
