Slide 4 shows that the number of these critical streamgages was declining at a fairly rapid rate from 1980 until 1998. This slide also shows the dramatic effect in 2001 and 2002 of the NSIP funding increase in 2001 on the growth of the number of streamgages designated to meet Federal needs. Because of level funding and inflationary cost increases, the number of NSIP streamgages started declining again in 2004 and another decrease is expected when 2005 values are all compiled.
