Marine commission warns of growing sedimentation, invasive species and rising costs on county lakes

Summary
The Lake Wilder Marine Commission told Gaston County commissioners it faces mounting sedimentation and invasive‑plant problems, expanding treatment acreage and higher administrative costs that could prompt a rate increase; commissioners asked staff to explore grants and coordination options.
Ray Weber, executive director of the Lake Wilder Marine Commission, told the Gaston County Board of Commissioners on Nov. 17 that sedimentation and invasive plants are the commission’s top concerns and that treatment and administrative costs are straining reserves.
Weber said volunteer river‑sweep work collected nearly 9,000 pounds of debris this October with 222 volunteers, and that the commission subsidizes swim‑guide water testing that draws thousands of summer views. He said sedimentation remains the long‑term problem affecting water clarity and lake capacity and urged stronger runoff controls and dredging around shorelines to protect future lake capacity.
The commission discussed inter‑basin transfers, saying it generally supports access to water but wants stricter sedimentation controls and runoff mitigation as conditions of transfers. Weber said the commission has worked with municipal partners and noted some site‑plan and permitting improvements in Gaston County aimed at reducing sedimentation during development.
On invasive species, Weber described ongoing hydrilla control efforts, periodic carp introductions and chemical treatments, and expanded action on lyngbia (a cyanobacterium). He said Lake Wylie treatment acreage and Mountain Island treatments have increased and that Gaston County faces roughly 1,200 acres requiring attention. Weber reported that treatment costs have risen (citing a move from about $31,000 to $41,000 for Lake Wylie in recent years) and that Lake Gaston faces a roughly $1.3 million shortfall in treatment funding.
Weber also flagged higher administrative expenses — audit, legal and operating costs have grown — and said the commission has not raised rates in about a decade. Because state law requires equal cost‑sharing among participating counties, the commission is considering options, including a possible rate increase, to restore parity and avoid depleting reserves.
Commissioners asked whether the commission has pursued grants (Weber said not yet but that grants are an allowable option) and how personal watercraft insurance and rental‑boat regulations would work in practice; Weber said the charter‑boat regulation portion was pulled because federal Coast Guard rules apply and that the commission plans a 2026 phase of implementation for lake regulations while exploring state‑level options.
The commission asked staff to continue researching grant opportunities and legal options and to return with cost scenarios for board consideration.
