It worked for me, do you have the latest version of ggplot2 released a  
few days ago (ggplot2_0.7) ?

Here's one way:

pred - data.frame(GPP = f, TSS = y)
qplot(TSS, GPP, data=r, colour=RiverMile) +
geom_line(data=pred, colour =black)

* ggplot2 works with data frames, so the key is to create one from
your model predictions.  Naming the variables to match the names of
the model inputs makes sense, and saves some typing.

*  You no longer need to specify xlim because ggplot2 knows about
everything you are plotting and can calculate the limits
appropriately.

* You have have to manually set the colour in geom_line to override
the default mapping that you created between colour and RiverMile.
