I'd assume they'd put these pretty close to the surface, lowers the water pressure and makes it more accessible

If you read the article it includes this line:

The idea is relatively simple: hollow concrete spheres are installed at a depth of several hundred metres.

The pressure is needed to drive the turbine, cause just gently-flowing water isn't going to cut it.
