Discharge values for three subcatchments (B201, B203, B204) of Bull Creek plus another nearby small catchment in the Teakettle Experimental Forest (T003). Values are presented by water year (previous October 01 through September 30 of named year). 15 min data were compressed to hourly and daily during the data processing procedure. B201, B203, and B204 flow is channelized through two Parshall flumes (small 2 feet). T003 flow is channelized through a 120 degree v-notch weir. At all sites stream stage and discharge are measured using a Teledyne-Isco 6712 with 730 bubbler. High flow stream stage and discharge are measured using an Advanced Measurements & Controls Inc. Aquarod AR100

This met station is located at the Bull Creek site of the Kings River Experimental Watershed (KREW). Both the Providence and Bull Creek met stations were erected by the Forest Service Pacific Southwest research station as part of the KREW project using the same methods and sensors. Data processing was conducted by the CZO using the same programs. The Bull creek site acts as a nearby paired area, approximately 400 m higher in elevation than the Providence sites.

本数据集包含公牛溪（Bull Creek）三个子汇水区（B201、B203、B204）以及邻近茶壶实验林（Teakettle Experimental Forest）的另一小型汇水区（T003）的径流量数据。数据按水文年划分，即对应年份的前一年10月1日至当年9月30日。数据处理过程中，将15分钟分辨率的原始数据汇总为小时级与日级数据。B201、B203、B204的径流通过两台帕歇尔水槽（Parshall flume，小型2英尺规格）进行渠化测流；T003的径流则通过120°V形缺口堰（v-notch weir）渠化测流。所有站点的河道水位与径流量均采用Teledyne-Isco 6712型设备搭配730型气泡式水位计进行测量；高流量场景下的河道水位与径流量则使用先进测量与控制公司（Advanced Measurements & Controls Inc.）生产的Aqarod AR100进行监测。

本气象站位于国王河实验流域（Kings River Experimental Watershed, KREW）的公牛溪站点。普罗维登斯（Providence）与公牛溪气象站均由美国林务局太平洋西南研究所搭建，作为KREW项目的一部分，二者采用相同的布设方法与传感器。数据处理工作由临界带观测站（Critical Zone Observatory, CZO）使用统一的程序完成。公牛溪站点作为邻近的对照样区，其海拔较普罗维登斯站点高出约400米。相关方法（包括所用传感器信息）与站点详情可参阅以下链接：https://eng.ucmerced.edu/snsjho/files/MHWG/Field/Southern_Sierra_CZO_KREW/Bull_Creek/Discharge/Level_1b/Bull_stream_Methods.txt 以及https://eng.ucmerced.edu/snsjho/files/MHWG/Field/Southern_Sierra_CZO_KREW/Bull_Creek/Discharge/Level_1b/Bull_stream_site.txt。
