In 2024, Lake LBJ experienced an extreme weed bloom because invasive zebra mussels cleaned the water so well that light reached more of the lake bed than before. The weeks choked the water, preventing people and watercraft from moving through it.
A few KCPOA community members volunteered for a committee to consider how best to address the cove weeds. In Spring 2024, the community accepted this ad hoc committee's recommendation to hire Lochow Ranch Pond and Lake Management, a company that held longstanding contracts with the Texas Parks and Wildlife Department to treat lake weeks and other aquatic invasive plants, to treat the weeds in the cove. The treatment plan was based on the location and intensity of lake weed, versus a predetermined schedule, using contact herbicides.
KCPOA also approved a special assessment to fund the weed treatment, with off-water lot owners contributing a flat fee and on-water lot owners contributing based on linear feet of waterfront. Since the treatment plan called for as-needed treatments, the exact cost could not be determined in advance. Any funds collected for this purpose but not needed were to be held separate.
In 2025, the community applied for and received an Invasive Aquatic Vegetation Management Rebate from the Lower Colorado River Authority, which refunded 50% of the weed treatment costs.
As of Spring 2026, the community has held unused lake weed assessment funds in a long-term CD to earn interest income.
