Automatic tracer-dilution method used for stage-discharge ratings and streamflow hydrographs on small Iowa streams Automatic tracer-dilution method used for stage-discharge ratings and streamflow hydrographs on small Iowa streams
An automatic system was designed to concurrently measure stage and discharge for the purpose of developing stage-discharge ratings and high flow hydrographs on small streams. Stage, or gage height, is recorded by an analog-to-digital recorder and discharge is determined by the constant-rate tracer-dilution method The system measures flow above a base stage set by the user. To test the

Influence of ingested lead on body mass of wintering canvasbacks Influence of ingested lead on body mass of wintering canvasbacks
We determined the prevalence of lead shotgun pellets in gizzards of canvasbacks (Aythya valisineria) collected at Catahoula Lake and the Mississippi River Delta, Louisiana, during winter 1987-88 to assess the influence of ingested lead shot on canvasback body mass. The prevalence of ingested lead shot was significantly higher at Catahoula Lake (27%) than at the Mississippi River Delta (4...

Regional evaluation of hydrologic factors and effects of pumping, St Peter-Jordan aquifer, Iowa Regional evaluation of hydrologic factors and effects of pumping, St Peter-Jordan aquifer, Iowa
The St. Peter-Jordan aquifer includes the Cambrian Jordan Sandstone and the overlying Ordovician Prairie du Chien Group and St. Peter Sandstone. The aquifer is present throughout Iowa and is confined beneath other aquifers in much of the State. Information on the aquifer available from drillers and contractors, provided estimates of aquifer transmissivity values ranging from about 500 to...
