Warning Systems 1. It is recommended that WRMD expend additional efforts focused on those communities identified in the high priority group towards specific identification of risk in each community‟s watershed, for a given flood event. This effort would benefit from the acquisition of additional detailed spatial information to determine exactly what resources (e.g., critical infrastructure) are at risk in each community‟s watershed, for a given flood event. The collection of community plan and parcel data, identification of specific damage estimates and/or flood damages modeling, and mapping of critical infrastructure would greatly facilitate vulnerability studies for Newfoundland and Labrador. This information, combined with efforts to model flood inundation levels and hydraulics would not only help determine vulnerabilities, it would also guide the selection of the most appropriate flood forecasting and/or warning system. 2. It is recommended that the WRMD conduct a thorough performance review of the forecasting systems in place for the Humber and Exploits River basins. The main goals of this exercise being the identification of extendable information or approaches to other Newfoundland and Labrador watersheds, as well as the identification of data gaps in the current forecasting systems that could be filled with additional resources. 3. It is recommended that the WRMD maintain/update the decision matrix when new information becomes available which has founded the prioritization of communities that could benefit from a Flood Forecasting / Flood Warning System.
