Colorado – Croke Canal GIS based Canal Management

The Croke Canal, near Westminster, Colorado, has historically transported 450 cubic feet per second (cfs), well below its appropriation of 950 cfs. The City of Westminster contracted Riverside Technology, inc. (RTi) to develop a decision support tool to identify potential overtopping problems in transporting the full appropriation. Data available from the City included AutoCAD drawings and HEC-2 output for various discharges up to the maximum appropriation of 950 cfs. Using this information, RTi generated water surface profiles and spatial extent surfaces for each discharge scenario.

RTi manipulated this information using ArcInfo GIS and organized it in ArcView GIS. RTi developed a customized ArcView graphical user interface using AVENUE programming. This interface gave the user additional functionality while allowing for ease of use. The result was a comprehensive database that integrated spatial and tabular data in a user-friendly decision support tool.
