Surface waters of North Boggy Creek basin in the Muddy Boggy Creek basin in Oklahoma

Abstract

Analysis of short-term streamflow data in North Boggy Creek basin indicates that the average runoff in this region is substantial. The streamflow is highly variable from year to year and from month to month. The estimated total yield from the North Boggy Creek watershed of 231 square miles averages 155,000 acre-feet annually, equivalent to an average runoff depth of 12 1/2 inches. Almost a fourth of the annual volume is contributed by Chickasaw Creek basin, where about 35,000 acre-feet runs off from 46 square miles. Two years of records show a variation in runoff for the calendar year 1957 in comparison to 1956 in a ratio of 13 to 1 for the station on North Boggy Creek and a ratio of 18 to 1 for the station on Chickasaw Creek. In a longer-term record downstream on Muddy Boggy Creek near Farris, the corresponding range was 17 to 1, while the calendar years 1945 and 1956 show a 20-fold variation in runoff. Within a year the higher runoff tends to occur in the spring months, April to June, a 3-month period that, on the average, accounts for at least half of the annual flow. High runoff may occur during any month in the year, but in general, the streamflow is relatively small in the summer. Records for the gaging stations noted indicate that there is little or no base flow in the summer, and thus there will be periods of no flow at times in most years. The variation in runoff during a year is suggested by a frequency analysis of low flows at the reference station on Muddy Boggy Creek near Farris. Although the mean flow at that site is 955 cfs (cubic feet per second), the median daily flow is only 59 cfs and the lowest 30-day flow in a year will average less than 1 cfs in 4 out of 10 years on the average. The estimated mean flow on North Boggy Creek near Stringtown is 124 cfs, but the estimated median daily flow is only 3 1/2 cfs. Because of the high variability in streamflow, development of storage by impoundment will be necessary to attain maximum utilization of the available water supplies in this region. The surface waters of the North Boggy Creek basin are of excellent quality, being suitable for municipal, agricultural and most industrial uses. The concentration of the dissolved mineral content is usually about 75 ppm (parts per million) and the hardness about 50 ppm. The water is slightly acidic, with a range of pH values from 6.5 to 7.0. This report gives the estimated average discharge at gaging stations and 3 selected other sites in the basin for the 16-year period October 1938 to September 1954, used as a base period in this report. Duration-of-flow data for selected percentages of the time are shown for the period of observed record on North Boggy and Chickasaw Creeks; similar data are estimated for the base period 1938-54. The basic records in the basin are presented on a monthly and annual basis (through March 1958). For other sites at which discharge measurements have been made, a tabulation of observed discharge is given. These data have been correlated to obtain information on the low-water portion of the duration curves at 2 of the sites. (available as photostat copy only)
