I visited Rattray Marsh today, because I was in the area. Just an FYI, there are no exposed mudflats. The water level is quite high, and would have been even without last night's rain because there is effectively no barrier beach. The marsh is at lake level.
It's still an interesting place to visit, but don't count on finding shorebirds. The most remarkable thing was the lack of ducks. I saw no ducks of any kind until I was leaving. Two Mallards swam into view on my last look over the marsh.
