History of WCMSHistory of WCMS

• Originally done in ArcInfo with AML• Made into a project file in ArcView 3.x• Many tools were implemented in the

“CHIA” extension for ArcView 3.x • Currently implemented as an extension

for ArcMap (ArcGIS 8.3).

Goals of SystemGoals of System

• Access and view data by bringing it to the desktop with ArcMap.

• Customized interface for ease of use.

• Answer common questions related to water quality modeling and stream flow for use in CHIA analysis.

• Assist efforts to implement Hydrologic Simulation Program Fortran (HSPF) modeling.

Future DirectionFuture Direction

• Work is ongoing to create tools for use with the Hydrologic Simulation Program Fortran (HSPF) model.

• 1:24,000 scale “Segment Level Watersheds” and NHD will provide higher resolution data for better analysis.
