• Regarding the use of WinTR-55 in Wisconsin.
  • The program has been released by NRCS at a national level however, Wisconsin NRCS does not recommend its use in Wisconsin at the present time.
  • There are several components of the model that need to be calibrated for Wisconsin. Initial calculations indicate that the WinTR-55 program will significantly overestimate peak discharge values and that its hydraulic calculations for outlet pipes are inaccurate.
  • Until calibration is performed, you should use the previous version (2.1) of TR-55 or TR-20.
  • Please pass this message along to partner agencies, municipalities, and private engineering firms as appropriate.
