Low-Flow Characteristics and Mean Annual Discharge of North Branch Manitowoc River at Potter, Wisconsin

The low-flow characteristics presented in this report are the annual minimum 7-day mean flows at the 2-year recurrence interval and 10-year recurrence interval. They were determined just downstream from the confluence of the three streams forming the North Branch Manitowoc River and, based on natural-flow conditions, are 0.0 cubic foot per second (0.0 cubic metre per second). Observations made in October 1974 showed that the natural discharge of the three streams forming the North Branch Manitowoc River was 0.0 cubic foot per second (0.0 cubic metre per second). A discharge of 0.30 cubic foot per second (0.008 cubic metre per second) was measured in the tributary from Hilbert but this was predominantly effluent from the sewage-treatment plant and a cheese factory in Hilbert. The mean annual discharge for the North Branch Manitowoc River at Potter is 27 cubic feet per second (0.76 cubic metre per second). This was based on the estimated and recorded discharge for June 1, 1974, to May 31, 1975, for the North Branch Manitowoc River at Potter site and an adjustment based on the long-term mean annual discharge at gaging station 04086000, Sheboygan River at Sheboygan.

Low-flow Characteristics of Eau Claire River Basin near Antigo, Wisconsin

This report presents low-flow characteristics at six sites on streams in the Eau Claire River basin near Antigo, Wis., where applications for irrigation permits were made. The low-flow characteristics presented are the annual minimum 7-day mean flows at the 2-year recurrence interval and 10-year recurrence interval. A seepage run made October 10, 1974, showed a substantial gain in discharge from site 2 (3.75 ft3/s [cubic feet per second] or 0.11 m3/s (cubic metres per second) to site 6 (30.6 ft3/s or 0.87 m3/s) on the East Branch Eau Claire River and from site 12 (3.98 ft3/s or 0.11 m3/s) to site 16 (18.1 ft3/s or 0.51 m3/s) on the West Branch Eau Claire River; a fairly constant discharge between sites 6 (30.6 ft3/s or 0.87 m3/s) and 11 (32.3 ft3/s or 0.91 m3/s) on the East Branch and sites 16 (18.1 ft3/s or 0.51 m3/s) and 20 (18.8 ft3/s or 0.53 m3/s) on the West Branch; and a substantial gain in discharge from site 23 (57.3 ft3/s or 1.62 m3/s) to site 24 (63.4 ft3/s or 1.80 m3/s) on the Eau Claire River. A gaging station was established at the downstream potential irrigation site to collect continuous stage and discharge data on streamflow to assist the Wisconsin Department of Natural Resources in the regulation of irrigation withdrawals.

Streamflow Characteristics of Klawitter Creek Basin near Westfield, Wisconsin

This report presents low-flow characteristics and mean annual discharge for a site on Klawitter Creek, where an application for diversion of streamflow has been made. This information will be used by the Wisconsin Department of Natural Resources to determine the availability of irrigation water from the stream while maintaining sufficient streamflow to support fish. The study was done in cooperation with the Wisconsin Department of Natural Resources, as part of the Wisconsin low-flow program.

Low-flow characteristics of Wisconsin streams at sewage-treatment plants

Low-flow characteristics of Wisconsin streams at 415 sewage -treatment plants are presented in this report. The low-flow characteristics presented are the annual minimum 7-day mean flow that occurs on the average of once in 2 years (Q7, 2) and the annual minimum 7 -day mean flow that occurs on the average of once in 10 years (Q7, 10). The low-flow characteristics at most sewage-treatment plants were determined by correlating base-flow measurements at the sewage- treatment plants to the concurrent daily mean flow at continuous-record gaging stations in the area. The Q7, 2 and Q7, 10 discharges determined by a frequency analysis at the continuous-record gaging stations were used to estimate the Q7, 2 and Q7,10 at the sewage-treatment plants. For some sewage-treatment plants the low-flow characteristics were also determined by frequency analysis at nearby continuous -record gaging stations or correlation analysis at nearby low-flow, partial-record stations. The accuracy of the estimated low-flow characteristics is evaluated according to the type and amount of data available used to determine the low-flow characteristics. The accuracy determined by the standard error of estimate for the 10-year low flow (SE10) ranged from 18 percent at continuous -record gaging stations to 70 percent when only three base-flow measurements were available. The SE10 of 70 percent is larger than anticipated when the project was initiated. This was the result of extremely poor base-flow conditions during the 2-year data-collection period.
