Sen. Alex Padilla, D-Calif., and a bipartisan group of House members are moving forward with separate legislative efforts aimed at strengthening water supply reliability and drought resilience for California, with a particular focus on the Central Valley and the Colorado River Basin.

Padilla has introduced a package of bills designed to bolster long-term water security across the state, while also advancing a bipartisan measure in the Senate to support ecosystem restoration along the Lower Colorado River.

Padilla’s broader legislative push centers on improving drought preparedness and water management tools as California braces for increasingly volatile hydrologic conditions. The proposals emphasize investments in water recycling, groundwater management, storage and conservation projects intended to help communities and farms adapt to prolonged dry periods and extreme weather swings.

In a separate development, Padilla announced that his bipartisan bill to reauthorize support for the Lower Colorado River Multi-Species Conservation Program cleared a key Senate committee. The program is a long-running partnership among federal agencies, states, tribes, and water and power users to restore habitat for endangered species while protecting water and energy operations along the river.

The measure aims to ensure continued federal backing for habitat restoration and species protection work tied to the river system, which supplies water to millions of residents and vast agricultural acreage in California and across the Southwest. For California growers dependent on Colorado River deliveries, supporters say the program helps stabilize regulatory conditions and maintain access to critical water supplies.

The lawmakers framed the effort as a bipartisan attempt to address chronic water shortages that have forced farmers to fallow land, switch crops and rely more heavily on groundwater in recent years.

Correction: An earlier version of this article incorrectly suggested Reps. Valadao and Panetta had authored water legislation as well.
