Normal

Target Flows

  • March 1 - 15 : 3350 CFS
  • March 16 - 22 : 1800 CFS
  • March 23 - 31 : 2400 CFS
  • April 1 - 30 : 2400 CFS

Variables and Values

  1. The mean February streamflow for the Platte River near Grand Island gage (provisional USGS data) was 1,710* cubic feet per second, equivalent to the 51.3 percentile level of 1947-1994 February conditions. (*The USGS streamflow gage at Grand Island reported "ICE" conditions for the entirety of February.  Data from the Overton gage was used as a surrogate)

Hydrologic Conditions Index
0.55

For this period, the threshold index value is 0.25 for "normal" conditions. The current index value is less than this and constitutes "NORMAL" conditions.
 
Note that for the March-April period, there are only "dry" and "normal" designations because "wet" targets are the same as "normal" targets for this period.
