Current status of streamflow near Grand Island, Nebraska (USGS Web page)

Past hydrologic condition designations (May 2007 to present)

1. Determined as described in Section 11, Appendix D of the Platte River Recovery Implementation Program Water Plan. The variables evaluated and the calculations resulting in this determination are detailed on the hydrologic conditions calculation page. For an overview of the methodology developed, see 'Characterization of Hydrologic Conditions to Support Platte River Species Recovery Efforts', Journal of the American Water Resources Association, 42(5):1391-1403.  Note that for some periods of the year, no "wet" flow targets apply; in these cases any conditions that are not "dry" are labeled "normal".

2. As described in the Platte River Recovery Implementation Program Water Plan, Section 11, Appendix E ("fixed daily targets"), and Appendix A-5 ("weighted monthly" targets).  These targets may change if the hydrologic condition changes when next evaluated.
