2022 Arkansas Nutrient Reduction Strategy Update

In 2018, staff from Arkansas Natural Resources Division began the process of updating the Arkansas Nutrient Reduction Strategy (ANRS). Over the last several years, a new strategic prioritization methodology for evaluating nutrient trends across was developed. The statistical methodology evaluates water quality monitoring data availability and ecological thresholds to determine a tiered classification system. Tier 1 watersheds demonstrated the highest need for nutrient reduction and thus are top priority for 319(h) funding. Tier 2 watersheds often had limited water quality, but data indicates nutrient reduction are warranted, which also prioritizes 319(h) funding. Tier 3 and Tier 4 watersheds had fewest lines of supporting evidence suggesting nutrient reduction and will not be prioritized for project funding. Additionally, the revision of the 2022 ANRS includes specific and strategic framework for goals and strategies for the implementation of the ANRS.

Initiated by the 2014 Arkansas Water Plan update and Arkansas's participation in the Gulf of Mexico Hypoxia Task Force, the Arkansas Nutrient Reduction Strategy (ANRS) is a strategic framework that outlines opportunities, both regulatory and voluntary, which are available to improve overall aquatic health and viability in Arkansas waters for recreational, economic, environmental, and human health benefits. The ANRS is not a regulatory document and does not supersede existing water laws governing water quality issues in Arkansas. Rather, it focuses on outreach and "grass-roots" implementation of nutrient reduction activities. Arkansas has invested significant effort to address point and non-point source nutrient loading through state, federal, and private partnerships. Partnerships with local, county, state, federal, non-profit, academic, and for-profit private sector entities are necessary for: a) mobilization and coordination of available resources, b) consistent interpretation and implementation of water management policies, c) long-term support at the national, state, and local levels, and d) advancement of science-based technologies, methods, and new nutrient reduction techniques.

The strategic framework recognizes that achievement of water quality goals requires iterative and collaborative processes which, when implemented over time, result in incremental progress toward improvement goals. Those processes must be adaptable to changing conditions and should adhere to the following guiding principles

  • Strengthening existing programs;
  • Promoting voluntary, incentive-based, cost-effective nutrient reduction measures;
  • Incorporating adaptive management and flexible strategic planning;
  • Leveraging available financial and technical resources;
  • Pursuing market-based opportunities and solutions.

An integrated approach, as defined in this strategic framework, represents a "sustained multi-discipline, multi-sector effort to reduce point and non-point nutrient loading and improve water quality through publicly supported strategies." These efforts require consistent cooperation and communication on the "ground-level" and represent a "bottoms-up" versus "top-down" approach to nutrient reduction. Arkansas's Conservation Districts are on the "ground-level," active in local communities, and pioneer the implementation of innovative practices. These "grass-root" connections are essential to working with private, state, and federal entities to improve water quality through public policy, public outreach and education, project implementation research, and water quality monitoring in priority watersheds.

The purpose of the ANRS is to reduce nutrient concentrations in Arkansas’s watersheds, providing local benefits and helping to shrink the Gulf Hypoxic Zone. This goal will be accomplished by working closely with our stakeholders to adaptively manage and implement relevant practices and programs to safeguard state and regional economic prosperity, environmental quality, and recreational opportunities for current and future generations.  The three main goals of ANRS are:

  1. Increase or maintain downward nutrient trends in Tier I watersheds.
  2. Enhance water quality monitoring and increase or maintain downward nutrient trends in Tier 2 watersheds.
  3. Continue efforts to reduce nutrients in all watersheds.
