Well that's because when the sun shines its rays hit the water ( streams ) and as the stream moves it breaks the sun's rays and forms a reflection that resembles stars!

The stream resembles the stars is because that the stream, the water current sparkles due to the sunshine. and stars indeed sparkle. therefore, the streams shiny appearance is just expressing that it shines and sparkles as the sky full of stars does. 

Hope this helps.
