Long-term record of lake and stream biogeochemistry from the Loch Vale Watershed, Rocky Mountain National Park, Colorado, USA: 1981-2024

The Loch Vale Watershed (LVWS) Project is a long-term research and monitoring program that addresses watershed-scale ecosystem processes, particularly as they respond to atmospheric deposition and climate variability. The LVWS is a 7-km2 high-altitude basin located within Rocky Mountain National Park in the Colorado Front Range (Colorado, United States of America). This dataset includes year-round measurements of physical water parameters, nutrients, major ions, trace metals, silica, and chlorophyll collected from lakes and streams within the LVWS basin.

洛赫谷流域（Loch Vale Watershed, LVWS）项目是一项长期研究与监测计划，旨在探究流域尺度的生态系统过程，尤其是其对大气沉降与气候变率的响应。该流域为面积7平方千米的高海拔盆地，坐落于美国科罗拉多州前落基山脉区域的落基山国家公园内。本数据集包含了从LVWS流域内湖泊与溪流中采集的全年监测数据，涵盖水体物理参数、营养盐、主要离子、痕量金属、二氧化硅以及叶绿素等指标。
