Measuring Aquatic Habitat to Support Environmental Modeling and Local Fisheries in Northern Utah

This data set contains measurements for discharge in cfs and cms, stream temperature in °C , dissolved oxygen (DO) in mg/L and %/L, total dissolved solids (TDS) in µs/cm, pebble count, and geomorphic condition, at sites in the Weber River Basin and Bear River Basin. Discharge was measured using a Marsh McBurney hand-held flowmeter. DO, TDS, and stream temperature were measured using a YSI Pro 2030 water quality probe. Pebble count was conducted using a modified Wolman procedure where a random pebble is picked up every step diagonally across a stream in a zig-zag pattern until at least 100 pebbles are measured. The pebble is then measured to obtain size and recorded. Geomorphic condition was assessed visually by taking note of conditions such as stream complexity (presence or lack of pools, riffles, meandering thalweg etc.), percent shade on stream, flow and depth variability, bank stability, access to floodplain, wood recruitment, unnatural barriers and condition and quantity of riparian vegetation. Based on the these conditions, a classification of excellent, good, moderate, or poor was assigned. Atmospheric pressure, wind speed and air temperature were measured with a Kestrel handheld weather meter, cloud cover was assessed visually. A site key in addition to the date, time and location (latitude/longitude and UTM) is included. Not all sites have values for discharge and pebble count due to hazardous conditions.

本数据集收录了韦伯河流域和熊河流域各监测点的流量（单位：立方英尺每秒cfs和立方厘米每秒cms）、水温（单位：摄氏度°C）、溶解氧（DO）浓度（单位：毫克每升mg/L和百分比/%/L）、总溶解固体（TDS）浓度（单位：微西门子每厘米µs/cm）、砾石计数以及地貌状况等测量数据。流量测量采用Marsh McBurney手持式流量计进行。溶解氧、总溶解固体和水温则通过YSI Pro 2030水质探测仪进行测定。砾石计数采用改良的Wolman方法，在河流中以之字形路径随机选取至少100颗砾石进行测量，并记录其尺寸。地貌状况通过视觉评估，包括河流复杂度（水池、浅滩、蜿蜒河槽等的存在与否）、河流遮荫百分比、流速和深度的变化性、河岸稳定性、对洪泛平原的可达性、木材的招募情况、非自然障碍物以及河岸植被的状况和数量。根据这些条件，对地貌状况进行优秀、良好、中等或较差的分类。大气压力、风速和气温通过Kestrel手持式气象计进行测量，云量通过视觉评估。除了日期、时间和位置（纬度/经度和UTM坐标）外，还包括一个现场关键字。由于存在危险条件，并非所有站点都有流量和砾石计数的值。
