Should your state government prioritize funding for local water quality monitoring programs?

Missouri will lose critical federal funding for the Statewide Lake Assessment Program and the Lakes of Missouri Volunteer Program by 2026. This shortfall stems from the expiration of an EPA waiver that previously allowed section 319 funds to support non-treatment monitoring efforts.

Why it matters

The loss of these programs threatens to end five decades of water quality research as the state lacks a dedicated budget for such monitoring. Without ongoing data collection, officials warn that identifying pollution trends or regulating water quality will become significantly more difficult.

Researchers monitor more than 65 lakes using standardized protocols to measure water parameters, including data spanning over 50 years. Observations have already tracked increased chlorophyll levels in the Table Rock Lake James River arm over the past 29 years.

The players

Statewide Lake Assessment Program

This research initiative monitors water quality parameters across more than 65 lakes in Missouri.

Lakes of Missouri Volunteer Program

This program coordinates volunteer efforts to collect essential water quality data across the state.

The details

The programs, which monitor water quality across the state, do not qualify for long-term section 319 funding because they focus on observation rather than active water treatment. To cope with the funding gap, staff may resort to storing collected water samples in freezers until a sustainable financial solution is secured.

The Statewide Lake Assessment Program monitoring initiative began in 1978.
Yearly assessments for the program have been conducted since 1989.
The federal waiver currently supporting the programs expires in 2026.
Training for new volunteers is typically scheduled for spring 2027.

The Big Picture

This funding expiration underscores the challenges states face under the Clean Water Act's Section 319 nonpoint source management program. The potential cessation of these long-term assessments signals a shift away from data-driven oversight for regional water bodies.

The loss of consistent lake monitoring could limit the state's ability to detect harmful algae blooms or pollutants that affect public recreation and local ecosystems. Without this data, Missouri residents may face reduced transparency regarding the safety of water in popular destinations like the Lake of the Ozarks.

The takeaway

Maintaining long-term environmental research requires stable, dedicated funding beyond temporary federal waivers. Citizens concerned about local water quality should monitor state legislative budget debates for future appropriations related to environmental monitoring.
