According to the City of Guelph Sports-field Status link (http://guelph.ca/living.cfm?itemid=77425&smocid=1627):

ALL SPORTSFIELDS ARE CLOSED FOR TONIGHT!!

RCMSPL

All games are cancelled for tonight and have been rescheduled for August 18th.
I realize this leaves some teams with 3 games in that week, but we really have no choice at this point as we need to complete all games before we can begin our playoffs!

GTCSPL

University:

GAMES ARE STILL SCHEDULED TO GO (barring anything unforeseen)!

Marden Park:

All games scheduled for tonight have been cancelled as the diamond is under water.

Guelph Lake:

All games scheduled for tonight will be rescheduled for a later date.

All cancelled games have been rescheduled wherever they could fit into the schedule.
