Needing Information building lakes and rivers with a photo background..

[redrunneru1]

I am new to the BTB building and I race in the Unlimited hydroplane racing league...I would like to make a local lake here in my state that the hydros ran at..Is there a way to make a water texture to race on with the boats and use a photo background as scenery? and maybe change a marker as a boey for the turns.....??? thanks DG.:struggle:
