I wonder if they get a tidal type effect in some really big dams or if the net flow downstream negates any possible influence only if you can wobble it back and forth.

The effects are cumulatively small but not proportionally insignificant when compared with the natural variation in the system. Basically water is impounded near people, more people live in the most habitable areas and water when it is impounded acts as a point like the weights on a car wheel. Most people in the world live in the northern hemisphere and closer to the temperate latitudes meaning the weight distribution of stored water is skewed to the north and the point load is further from the rotational axis. So like a pirouette weight further from the rotational axis will have a profound effect on the speed of rotation. Out of all this day length can be affected by a very small amount and axial shift can be affected by a very small amount. Both are proportionally large when compared with overall change.

If so could you email me a PDF or I can look at a hard copy on the weekend if you have it. hey mate do you have access to those articles?

If you really want to get your hackles up over North America's abuse of river systems, read Cadillac Desert by Marc Reisner. I'm getting all riled up just thinking about it...
