High Rock Lake Nutrient Management Strategy
High Rock Lake is experiencing water quality issues due to algal blooms that may produce harmful toxins and can cause illness if exposed to humans and pets. The Department of Environmental Quality is currently drafting new state requirements (called “rules”) to address the increased nutrients in this watershed causing the blooms. These rules are expected to impact a wide range of nutrient sources, including, but not limited to, impervious surfaces, stormwater runoff, agriculture, wastewater and riparian buffers.
Beginning in 2022, an informal engagement process was initiated to bring together a wide range of stakeholders from various sectors and regions within the watershed. A steering committee has been selected with membership spanning a diverse cross-section of individuals and groups representing various interests and perspectives. In addition, technical advisory groups (TAGs) have been convened to investigate different control strategies for nutrient sources in the area that drains to High Rock Lake. Phase I of the informal engagement process was completed in December of 2023, and the steering committee released its final report of recommendations for the division to consider during rulemaking.

Planning meetings are being scheduled throughout the rulemaking process and will continue in both informal and formal settings until rules have been adopted by the Environmental Management Commission and become effective. The public is invited to participate. Please contact Joey Hester (919-707-3675, joey.hester@deq.nc.gov) if you have questions or for more information about how you can participate.
High Rock Lake is presently impaired for several water quality parameters including chlorophyll a, turbidity, and pH. Because High Rock is among North Carolina’s largest and most eutrophic lakes, it has long been the subject of focused studies designed to support an anticipated nutrient strategy.
DWR concluded its lake and watershed modeling efforts with support from a technical advisory committee in 2016. As part of North Carolina's Nutrient Criteria Development Plan, the Scientific Advisory Council proposed a revised site-specific chlorophyll-a standard for the Lake, which was subsequently approved by the Environmental Management Commission and EPA in 2022 (see 15A NCAC 02B .0211(4)(a)). Nutrient management strategy development is ongoing with the consultation of watershed stakeholders, and a Steering Committee was convened to provide expert guidance for DWR's rulemaking efforts.
High Rock Lake Rulemaking Charter
The initial phase of informal stakeholder engagement concluded on December 12, 2023. A final stakeholder report is currently in development and will be finalized by the Steering Committee before being be made available for public download.
