HB 2421 Missouri House · 2026 Regular Session

Provides for the right to store water in a reservoir owned by the U.S. Army Corps of Engineers

This bill would grant water users who contract with U.S. Army Corps of Engineers reservoirs exclusive rights to "return flows" (water discharged back to the reservoir from their own treated wastewater facilities). It requires these rights to comply with state regulations and only apply when unused storage capacity exists in the reservoir. The policy directly affects municipal or industrial water users who treat wastewater and discharge it back into Corps reservoirs. The bill is currently in early legislative stages (prefiled and first reading).
