Red grass

I never knew there were so many kinds of grass. I've been browsing grass photos for over an hour, fruitlessly looking for a match for this red-topped, spiky beauty:

The grass grows about a foot deep, and covers a meadow beside Little River. The whole meadow looks red from a distance.

The meadow is dry and sandy, but floods when the river is high.

The closest match I found on E-Flora BC is cheatgrass, with a photo of a red field. The grass is common in BC, and E-Flora has two records in the Comox area. I'm not quite convinced that this is it, though.
