The approved FY24 CWMS "Other" budget was $2,875,000. As with ERC, the "Other" budget can be split into two categories: Sustainment and Development. Most of the "Other" budget for FY24 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 FY24 were the MMC and Headquarters USACE.
MMC CWMS National Implementation Program
The MMC provided $700,000 for software development in FY24. The funding was divided between the HEC-RAS, HEC-HMS, and CWMS software development teams. HEC also received $170,000 to support HEC-FIA and the Flood Damages Reduced effort. 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 Kansas City, Ft. Worth, Portland, Mobile, Savannah, Wilmington, and Jacksonville District offices along with the NWD Columbia River Division office to help water management staff fully implement all CWMS components. The figure and table below show a breakdown of funds per component.

Headquarters USACE
Headquarters provided $545,000 to operationalize use of ensembles in CWMS. Ensembles include flow time-series from National Weather Service River Forecast Centers and application of the many meteorologic datasets that are available to the public.
