January 29 – February 3, 2026

The Bottom Line

Congress is considering four bills to spend $10 million on studies to expand water access in Iowa, Minnesota, South Dakota, and Nebraska. These studies would help determine if the Lewis and Clark and Dakota Mainstem water systems can reliably serve more people in the region. All four bills, including S. 3725 and H.R. 7331, have been introduced and are currently waiting for committee review.

These four bills consist of two pairs of companion legislation introduced in both the House and Senate. S. 3725 and H.R. 7287 focus on the Lewis and Clark system, while S. 3736 and H.R. 7331 address the Dakota Mainstem project. This dual-track approach allows both chambers of Congress to consider the water expansion studies at the same time.
