Continuous water quality data from the Rio Chama below Abiquiu Reservoir, New Mexico, USA, 2020-ongoing

This data resource contains continuous water quality measurements (water temperature, specific conductance, turbidity, pH, dissolved oxygen) from the Rio Chama downstream of the Abiquiu Reservoir in northern New Mexico, USA. These data support the U.S. Army Corps of Engineers (USACE) Albuquerque District Reservoir Operations by quantifying the delivery of sediment to Abiquiu Reservoir as well as impacts of the reservoir on sediment retention and water quality. This site is located immediately downstream of the U.S. Geological Survey (USGS) site named “Rio Chama Below Abiquiu Dam, NM (08287000).\" Data were collected using a YSI EXO3 sonde, deployed in an ~12’ aluminum casing bolted to a concrete weir face and connected to a Campbell Scientific CR300 datalogger powered by a photovoltaic system. Data collection is ongoing, with this release spanning July 14, 2020 through June 30, 2024.本数据集包含美国新墨西哥州北部阿比丘水库（Abiquiu Reservoir）下游查马河（Rio Chama）的连续水质监测数据，监测指标包括水温、比电导率（specific conductance）、浊度（turbidity）、pH值及溶解氧（dissolved oxygen）。本数据集可支撑美国陆军工程兵团（U.S. Army Corps of Engineers, USACE）阿尔伯克基分区的水库调度作业，用于量化输入阿比丘水库的泥沙通量，以及该水库对泥沙滞留和水质的影响。本监测点位紧邻美国地质调查局（U.S. Geological Survey, USGS）编号为“新墨西哥州阿比丘大坝下游查马河（08287000）”的监测站点下游。监测数据由YSI EXO3多参数水质探头采集，该探头安装于长约12英尺的铝制套管中，通过螺栓固定于混凝土堰壁，并连接至由光伏发电系统供电的Campbell Scientific CR300数据采集器。目前监测工作仍在持续，本次发布的数据覆盖时段为2020年7月14日至2024年6月30日。
