SUMMARY
The cwcn has invested in Decision Support Systems (DSSs) for several years, in particular the basin DSSs
COllectively known as Colorado's Decision Support Systems (CDSS). The DSS efforts provide specific
solutions 10 meet the prioritized m."Cds or the eWeR and DWR and also provide a gcncral framework for data
management, modeling, analysis, and dissemination of information. The proposed Flood OSS prototype
recognizes the framework of COSS and, as much as possible, would be implemented in a way that uses CDSS
components and data, extends COSS with additional data and capabilities, and allows for continued reuse and
integration with CDSS components. A Flood DSS was initially envisioned as an impetus to statewide
digitizalion of designaled noodplains, a goal that has since been achieved Ihrough Ihe Slate's document imaging
system. Subsequently, the primary focus of the Flood DSS is to mcct the following needs: I) Provide a
clearinghouse of flood.hazard information for use by a variety of Users, 2) Provide timely and well-organizcd .
flood outlook data products for the emergency managers {e.g., Flood Task Force}, and 3} Provide a
clearinghouse of additional flood-related data, including weather modification, stn'am restoration, levce & dam
inventories, ctc. Thc ability to utilize flood ha7..ard infonnation from different sources in a GIS environment, as
well as access information from CWCB's Content Manager document system for interpretation togl.thcr with
spatial information, will greatly facilitate the etlcctivcness of decision-making. The OSS protolypc
demonstratcd this utility, and was helpful in garnering support to fully develop a statewide flood DSS. 'me
specilic objectives of Flood DSS developmcnt are to: I) Imple-mL'"t a web site to organize and dissemimlle
spatial data, via an ArclMS web site on a State web server, that will allow for a clearinghouse concept, 2)
Provide links betw<-cn selecled spalial and non-spatial data in order to maximize funetionalily oflhe 1001, and 3)
Allow CWCB Flood Protection stafr to increase the efficiency and Use of pertinent data for both inh:mal
decision making as well as eXll'rnal delivery.
