The excessive growth of aquatic macrophytes in a water system has a negative effect on the lake ecosystem. This article presents data on water parameters and sedimentation rates from sites that include different aquatic macrophytes at Tasik Berombak, a freshwater lake on Peninsular Malaysia's eastern coast. Areas with and were selected for sampling, while an area without aquatic macrophytes served as the control. At the lake's surface and bottom, temperature, conductivity, total dissolved solids, dissolved oxygen (D.O.), and pH were measured . The surface water was sampled for chemical analysis in the laboratory (chlorophyll-a, total suspended solids, total carbon, total organic carbon, inorganic carbon, total dissolved nitrogen, total dissolved phosphorus). Settling sediment was collected using cylinder traps deployed under the macrophytes at the bottom of the lake. The presented data includes the water parameters according to plant-base area, depth differentiation (top versus bottom), and variable correlation analysis. Understanding the impact of excessive aquatic plants on the lake ecosystem in a tropical environment requires information on water parameters and sedimentation rates from the aquatic plants. Therefore, these data can be used to monitor the impact of land use change on the aquatic plant community and, ultimately, the lake ecosystem.
水系统中水生大型植物的过度生长会对湖泊生态系统产生负面影响。本文展示了马来西亚半岛东海岸淡水湖贝龙巴克湖不同地点的水参数和沉积速率数据，这些地点包含不同的水生大型植物。选择了有[具体植物1]和[具体植物2]的区域进行采样，同时选取一个没有水生大型植物的区域作为对照。在湖面和湖底测量了温度、电导率、总溶解固体、溶解氧（D.O.）和pH值。采集地表水样本在实验室进行化学分析（叶绿素-a、总悬浮固体、总碳、总有机碳、无机碳、总溶解氮、总溶解磷）。使用部署在湖底大型植物下方的圆筒式陷阱收集沉降沉积物。所呈现的数据包括基于植物面积、深度差异（顶部与底部）的水参数以及变量相关性分析。了解热带环境中过多水生植物对湖泊生态系统的影响需要有关水生植物的水参数和沉积速率的信息。因此，这些数据可用于监测土地利用变化对水生植物群落以及最终对湖泊生态系统的影响。
