<br />by proximity to some identifiable feature and town; and by distance <br />upstream from mouth. Drainage area in square miles is given for all <br />stations, except for three partial record stations for which drainage <br />areas were not available. Statement of available record gives the period <br />during which observations of water temperatures were obtained in <br />conjunct ion wi th di scharge measurements. A pa ragraph of "remarks" Is <br />included for those stations where streamflow and temperature may have been <br />affected by reservoirs, diversions, return flow from irrigation, or other <br />factors. <br /> <br />Water temperature data for each station are summarized in two tables and <br />four graphs. The first table summarizes the observed temperatures for <br />the period of record giving the mean, standard deviation (S.D.), range <br />between the maximum and the minimum, and number of observations (N). <br />The five lowest and the five highest water temperatures are listed with <br />the corresponding time of observation, discharge, and date. All <br />temperatures are given to the nearest one-half degree Celsius. The <br />discharge is given In cfs. (cubic feet per second). <br /> <br />The second table is a statistical presentation of the observed temperature <br />data by month for the period of record. Included in this table are: <br />minimum and maximum temperature, range, mean, standard deviation, and <br />number of observations. <br /> <br />Three graphs show the frequency distributions of time of observation, <br />discharge, and temperature. The three distributions have a variable <br />scale on the X-axis showing the number of observations. The value "N" <br />represents the number of observations. The scale on the Y-axis for the <br />discharge and temperature frequency plots designates the midpoint of <br />each range. <br /> <br />The i nte rva 1 size of the ranges is given be low the graphs. I n the group <br />of largest discharges on the graph, the symbol> is used to indicate <br />discharges greater than a specified amount (for example, the station <br />06814000, Turkey Creek near Seneca, Ks. shows 13 discharges >439 cfs). <br /> <br />The fourth graph is a plot of temperature versus date, which illustrates <br />the distribution of all observed temperature data available. Some <br />inconsistency may occur between the number of plotted Items and the <br />monthly summary table because the computer program does not allow for <br />duplication of items. Both the Celsius and Fahrenheit scales are shown <br />for the convenience of the user. Basic data for the Items in this graph, <br />including data, time of observation, temperature, and discharge, are <br />available in computer accessible form at the office of the U.S. Geological <br />Survey in Lawrence, Kansas. <br /> <br />'" <br /> <br />. <br /> <br />4 <br />
