The main purpose of this legislation is to create an interest-bearing account specifically for non-Federal contributions to the Lower Colorado River Multi-Species Conservation Program. This program aims to protect and manage various species and their habitats along the Lower Colorado River. Key provisions of the legislation include the establishment of a new fund called the Non-Federal Funding Account. This fund will hold contributions made by state parties that are not federally funded. It will also earn interest, which can be used for program-related expenditures.
