Matthew Poole and continuators on Psalms 107:33

33. He turneth rivers into a wilderness , and the water-springs into dry ground:

Either 1. properly so called; which he can divert or dry up when he pleaseth, as sometimes he hath done. Or father 2. those grounds which are well watered, and therefore very fruitful, as the next verse explains this. And so the water-springs here and v. 35. and the standing water v. 35. are taken.

Into a dry ground, as it follows, which is like a parched and barren wilderness.
