Low-flow characteristics of streams in the Trempealeau-Black River basin, Wisconsin

Water-Resources Investigations Report 79-9
Prepared in cooperation with the Wisconsin Department of Natural Resources



Lov-flov characteristics of streams in the Trempealeau-Black River "basin are presented. Included are estimates of low-flow frequency and flow duration at 9 gaging stations, and low-flow frequency characteristics at 20 low-flow partial-record stations and 119 miscellaneous sites.

Ten equations are provided to estimate low-flow characteristics at ungaged sites and at sites where one "base-flow discharge measurement is available. The low-flow characteristics determined were the annual minimum T-day mean flow below which the flow will fall on an average of once in 2 years (Qj 2) a>n<3. once in 10 years (Q7 9io)« The equations were determined from multiple-regression analyses that related the low-flow characteristics at gaging stations and low-flow partial-record stations to basin characteristics. Drainage area, soil-infiltration rate, transmissivity, precipitation, snowfall, and base-flow index were the most significant parameters for these analyses.
