Abstract

Surface water budgets, calculated from base-flow discharge data, for several reaches of the West Nishnabotna River in Southwest Iowa, reveal two reaches with anomalously small incremental discharges. These small incremental discharges cannot be accounted for through evapotranspiration at the time of the discharge measurements nor can they be related to losses associated with shallow ground water withdrawals near the river. The small incremental discharges in the two reaches are interpreted as resulting from influent conditions at natural ground water recharge sites within each reach. The southernmost of these two sites is located near a major buried valley which may be conducting the influent river water into the subsurface, away from the river.
