Test River pH: Make an Indicator at Home

I need to test the ph of river. I need a method of making an indicator that I can make at home. Please help !

Welcome to PF;
Have you tried googling "make your own ph indicator"?

If you boil red cabbage - the water turns purple - the color is sensitive to pH.

Do you know approximately what pH to expect? Is the river badly polluted? Is there any animal life present in the water?

I remember making an indicator from the purple juice of "ink weed" berries. It turned green in an alkali, I think.
