The approved FY23 CWMS "Other" budget was $2,830,000. As with the ERC, the total budget can be split into two categories: Sustainment and Development. Most of the "Other" budget for FY23 was allocated for Development (enhancements). While CWMS is authorized to expend up to this budget, the funding received from "Other" sources may be less. These funds continue to have profound impacts in terms of the development and implementation of CWMS and related software. Contributors identified for FY23 were MMC and WMIST.
MMC CWMS National Implementation Program
The MMC provided $860,000 for software development in FY23. The funding was divided between the HEC-RAS, HEC-HMS, and CWMS software development teams. HEC also received $111,000 to support the HEC-FIA Flood Damages Reduced effort, which was in addition to the $860,000 for software development and support. HEC participated in monthly National Implementation Plan (NIP) coordination calls with the MMC and Headquarters. During these meetings, the team reviewed the progress of the NIP, discussed the status of software development, and planned future work (such as training opportunities). HEC staff also participated in "Field Helping the Field" visits to the Pittsburgh and Sacramento District offices with other experienced water managers to help districts fully implement all CWMS components.
The work activities (labor and contracts) that used MMC funds are shown and listed below.
