I have a Davis VP2 and I also have a stream running through the middle of
my garden.

It would be really nice to plot some graphs of rainfall against water
level and possibly programmatically predict when flooding is likely.

I think that you would be hard pressed to find any meaningful
correlation. The stream flows through your garden - so it has
come from somewhere else. You may get a better correlation with
rainfall data from the area of the source and course of the
stream.



The upstream catchment area is quite small and near, the source being about
1 mile away. It is spring fed so I would need to factor in rainfall over
some sort of moving average period and add on today's rain to get an
estimate of flow but I think it should be doable.

Looking at your location, I guess you are near to chalk-based
bedrock - so your catchment definition could be complex. I don't
envy you trying to to do this...
