RESERVOIR RISK MANAGEMENT
WHITE PAPERS
Why Current Water Management Strategies Are Failing
This foundational paper sets the stage by detailing the growing crisis in reservoir management and the systemic failures of existing strategies. Despite federal initiatives such as the Harmful Algal Bloom and Hypoxia Research and Control Act (HABHRCA) and the 2022 U.S. Government Accountability Office (GAO) report, current approaches remain reactive, focusing on crisis response rather than proactive risk prevention.
Key Takeaways:
A Worsening Crisis: Eutrophication and HABs are becoming more frequent, widespread and severe, threatening drinking water supplies, public health, and water security.
Systemic Failures: Traditional management relies on outdated methodologies that measure symptoms rather than addressing root causes.
Need for a Paradigm Shift: The GAO report calls for data-driven, risk-based methodologies to replace ineffective reactive approaches.
This paper argues that the only way forward is to embed formal risk management principles into reservoir operations, prioritizing root-cause analysis, proactive intervention, and predictive tools to prevent systemic collapse.

How Flawed Monitoring Methods Have Perpetuated Water Quality Decline
Historically, reservoir monitoring has been shaped by the Trophic State Index (TSI) and other conventional methods designed to measure symptoms rather than diagnose underlying risks. This paper critically examines why such approaches have failed to prevent HABs and hypoxia.
Key Takeaways:
Flaws in Traditional Metrics: The TSI relies on chlorophyll-a, phosphorus, and water clarity, which are symptoms of eutrophication, not causes. As a result, it encourages short-term symptomatic treatments that do not address the fundamental drivers of risk.
Misaligned Management Practices: Because traditional metrics fail to differentiate between harmful cyanobacteria and beneficial algae, they obscure critical early warning signs.
The Need for Risk-Based Monitoring: To effectively mitigate risk, leading indicators like hypoxia, sediment nutrient recycling, and phytoplankton pupolation dynamics must be measured.
This paper introduces the Reservoir Risk Assessment and Tracking System (RRATS) and the Reservoir Risk Index (RRI) as modern tools that replace flawed legacy methodologies with objective, data-driven risk assessment.

How Data-Driven Risk Management Can Transform Reservoir Operations
Building on the case for modernizing risk management, this paper explains how RRATS and RRI offer a transparent, objective framework for assessing, tracking, and mitigating risks in real-time. It details how these tools provide actionable insights for prioritizing interventions, allocating resources, and preventing HABs before they occur.
Key Takeaways:
Introducing RRATS & RRI: These tools provide a standardized, comparative framework to quantify risk across different reservoirs, tracking leading indicators rather than lagging symptoms.
Operational Benefits: RRATS enables real-time monitoring of critical drivers like hypoxia, sediment nutrient recycling, and phytoplankton biodiversity, while RRI distills this data into a single risk score that guides decision-making.
Case Studies Demonstrating Impact: A real-world example illustrate how these tools identified hidden risks in a seemingly stable reservoir and informed targeted interventions that successfully prevented HABs.
This paper provides the final step in the risk management framework—showing how RRATS and RRI operationalize proactive, science-based reservoir management, enabling water managers to make better, more informed decisions.

Why RRATS and RRI Matter
For too long, reservoir management has relied on reactive crisis response rather than proactive risk mitigation and crisis prevention. RRATS and RRI change this paradigm by transforming monitoring into predictive, proactive, risk management.
By integrating these tools into policy and practice, reservoir managers and stakeholders can:
- Identify and prioritize root causes of degradation rather than just symptoms.
- Proactively track and quantify risk to prevent harmful algal blooms before they occur.
- Improve resource allocation by focusing interventions where they will have the greatest impact.
- Shift from crisis management to long-term water security.
Without a transition to proactive, risk-based reservoir management, we will continue to see deteriorating water quality, increasing public health risks, exposure to litigation, escalating costs, and deteriorating water security.
