Data Summary |
Blue Earth County participates in the Minnesota State Climatology Office Rain Guage Network. Faribault County participates in the Minnesota State Climatology Office Rain Guage Network. Martin County participates in the Minnesota State Climatology Office Rain Guage Network. Blue Earth River Basin Implementation Framework, Phase I - Diagnostic (CWP) includes precipitation data from the South Central Minnesota Comprehensive County Water Planning Project (SCMCCWPP) Rain Gauge Network. Precipitation data collected during the sampling period were modeled for the watershed using Minnesota State Climatology methodology. SCMCCWPP sponsors a volunteer rain guage reader network. This volunteer rain guage reader network reports daily precipitation during the growing season (May through September) to their county Soil and Water Conservation District (SWCD). These data are sent to the Water Resources Center at Minnesota State University, Mankato, for entry into the Minnesota State Climatology database and for generation of contour precipitation maps. These data have been collected since 1992. |
