The approved "Other" budget for the CWMS program was $2,900,000 in FY25. As with ERC, the "Other" budget can be split into two categories: Sustainment and Development. Most of the "Other" budget for FY25 was allocated for Development (enhancements). While CWMS is authorized to expend up to this budgeted amount, the funding received from these sources may be less. These funds continue to have profound impacts in terms of the development and implementation of CWMS and related software. Contributors of "Other" funds in FY25 were the CWMS National Implementation Program (NIP) and Headquarters USACE.

CWMS National Implementation Program

The CWMS NIP provided $965,000 for software development in FY25. The funding was divided between the HEC-RAS, HEC-HMS, and CWMS software development teams. HEC participated in monthly CWMS 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 also received $10,000 to support HEC-FIA and the Flood Damages Reduced effort.

The CWMS NIP also supported three workshops in FY25: an HEC-HMS calibration workshop; a CWMS implementation workshop; and a Flood Damages Reduces workshop.

HEC staff also participated in Field Helping the Field visits to the Omaha, Walla Wall, and St. Paul District offices along with the NWD Missouri River Division office. A South Atlantic District/Divisions  follow-up meeting was held as well as a multi District workshop to discuss possible improvement to the CWMS software suite to better support hydropower modeling and data dissemination. The figure and table below show a breakdown of funds per component.
