Lutz creek is a small (9.69 ha) catchment located on Barro Colorado Island (BCI), a 1500‐ha island in Lake Gatún, the principal freshwater reservoir (425 ha, 26 m above sea level) of the Panama Canal watershed in central Panama. In 1972, a concrete V‐notch weir was installed on the creek, located at 9°09′42.8358″N, 79°50′15.6699″W, and hydrological record keeping began. The island was first established as a research station in 1923 and precipitation data collection was initiated in 1925. A meteorological tower, installed in 1972 and located a few meters from the weir, is currently instrumented to collect air temperature, relative humidity, wind speed and direction, evapotranspiration and solar radiation. In addition, since 1972, gravimetric soil moisture has been measured at least biweekly at 10 sites located throughout the Lutz Catchment above the location of the weir. Data collection and the administration of BCI are the responsibility of the Smithsonian Tropical Research Institute (STRI; https://stri.si.edu) which funds the data collection and storage. Data are in the public domain, entitled ‘Lutz Watershed And Meteorological Tower’ and are available at the STRI Physical monitoring website https://biogeodb.stri.si.edu/physical_monitoring/.

Lutz Creek分水岭，巴拿马巴罗科罗拉多州巴罗岛

卢茨克里克（Lutz Creek）是位于巴罗科罗拉多岛（BCI）上的一个小流域，该岛是加图恩湖中1500公顷的岛屿，加图恩湖是巴拿马中部巴拿马运河流域的主要淡水水库（425公顷，海拔26 m）。 。1972年，一条小V型槽堰安装在小河上，位于北纬9°09′42.8358″，西经79°50′15.6699″，并开始保存水文记录。该岛于1923年首次建立为研究站，并于1925年开始收集降水数据。1972年安装的气象塔位于堰口几米处，目前用于收集空气温度，相对湿度，风速和风速。方向，蒸散量和太阳辐射。此外，自1972年以来，至少每两周对重力土壤水分进行一次测量，测量范围位于堰区上方Lutz集水区的10个地点。史密森尼热带研究所（STRI; https://stri.si.edu）负责数据收集和BCI管理，该研究所为数据收集和存储提供资金。数据属于公共领域，名为“卢茨流域和气象塔”，可在STRI物理监视网站https://biogeodb.stri.si.edu/physical_monitoring/上获得。
