It appears drainage issues continue to plague Investors Group Field.

During Thursday night's game fans could be seen bailing water from a field level section.

The result, says the team, of a flash downpour of rain that lasted 20 minutes. A spokesperson says the water eventually drained.

One fan described it on Facebook like a waterfall coming down the stairs.

The owner of the stadium, Triple B, is embroiled in a lawsuit with the builder, Stuart Olson, over drainage, cracking and insulation issues that have hampered the stadium since it opened.

Triple B says the pooling issue from Thursday night's event will be addressed through the ongoing remediation process to fix all of the problems.
