Valley Creek, north branch, hourly hydrologic data

Valley Creek is the finest of about a dozen remaining trout streams at the fringe of the Minneapolis-St. Paul metropolitan area in east-central Minnesota. The stream is tributary to the St.. Croix River, a federally designated National Scenic Riverway, and therefore provides an important contribution to the biodiversity of the St. Croix’s watershed. Urbanization by the rapidly expanding metropolitan area may threaten the integrity of Valley Creek, and automated monitoring was begun in 1998-99 to document baseline conditions, to allow trends to be identified, and to calibrate predictive models.
This dataset consists of hourly values of stream flow, temperature, and specific conductance from the north branch of Valley Creek, near its confluence with the south branch, 1998-present.

瓦利溪（Valley Creek）是明尼苏达州中东部明尼阿波利斯-圣保罗都会区边缘仅存的十余条鳟鱼溪流中的翘楚。该溪流为联邦指定国家风景水道（National Scenic Riverway）圣克罗伊河（St. Croix River）的支流，因此对圣克罗伊河流域的生物多样性具有重要贡献。快速扩张的都会区带来的城市化进程可能威胁瓦利溪的生态完整性，为此研究团队于1998至1999年启动自动监测工作，以记录基线环境状况、识别变化趋势并校准预测模型。

本数据集包含1998年至今、瓦利溪北支流（靠近其与南支流汇流处）的溪流流量、水温及比电导率的逐小时观测值。
