Long-term naturalized streamflow for six sites in the Upper Wabash River basin

<p>In the Upper Wabash River basin in Indiana, the effects of land management and climate changes on streamflow trends may be masked by flood control reservoirs constructed in the mid-1960s. To investigate the impact of environmental changes on streamflow, historical daily data were used to estimate daily naturalized streamflow at six sites in the Upper Wabash basin. These sites include:  </p>

<p>1.     Wabash River at Huntington (USGS site number: 03323500)</p>

<p>2.     Salamonie River at Dora (USGS site number: 03324500)</p>

<p>3.     Wabash River at Wabash (USGS site number: 03325000)</p>

<p>4.     Wabash River at Peru (USGS site number: 03327500)</p>

<p>5.     Wabash River at Logansport (USGS site number: 03329000)</p>

<p>6.     Wabash River at Lafayette (USGS site number: 03335500)</p>

<p>The data published here correspond to the paper "Streamflow Impacts of Management and Environmental Change in the Upper Wabash River Basin" by S. Rahman and L. Bowling, published in the <em>Journal of Hydrologic Engineering </em>(//doi.org/10.1061/(ASCE)HE.1943-5584.0001750). Further details about the six sites and the Modified Drainage-Area Ratio Method used for estimating naturalized streamflow are available in the corresponding paper. Key takeaways from the study are: 1) Reservoir management has resulted in 36% and 38% decreases in annual maxima series (AMS) and Richards-Baker flashiness index (RBI), respectively, and a 21% increase in annual minima (MIN) for the most downstream location of the study area, Wabash River at Lafayette between 1971 and 2000. 2) Analysis of the naturalized streamflow time series indicates that there is an increasing trend in MIN and mean annual flow (MAF) across the watershed, as well as an increasing trend in the RBI and AMS.</p>

<p>This published dataset extends the original record from 2014 to 2023, offering a more comprehensive temporal scope for analysis. Titled <strong>“Naturalized_Streamflow_UpperWabash_1961_2023”</strong>, the dataset is available in “<code>.txt</code><code>” format</code>. It consists of seven columns—the first column lists the dates, and the remaining six columns provide naturalized streamflow data in cubic meters per second (m³/s) for each of the six sites in the Upper Wabash basin.</p>
