Occlusion Culling Dilemma
A low-latency (and frankly better) alternative to hardware occlusion queries is to make your own using indirect drawing. Simply draw a chunk's bounding box against the depth buffer and set the instance count of the indirect struct to one if any fragments are drawn. The next frame you can use these indirect commands to draw the actual chunk geometry and repeat the whole process. This has a guaranteed latency of one frame. More info here.

Occlusion Culling for Chunks?
One approach is to use occlusion queries, draw chunks which were visible last frame and then occlusion test the bounding volumes of chunks which weren't rendered and render the ones which pass using a shader based occlusion approach similar to this NVIDIA sample: https://github.com/nvpro-samples/gl_occlusion_culling

Occlusion Culling Dilemma
Have you come across Masked Occlusion Culling before? It renders geometry on the cpu into a simplified depth buffer using bit shifting. It would take a bit of rework to integrate, but it doesn't seem too bad.
What are some alternatives?
