My sense was that the answer is "no," but I would like to confirm. It would be worthwhile to identify "dependent" questions in the guide (that is, the ones that can be skipped based on an answer to a previous one).

Hello,
Can you ask this on a separate post, and if possible, provide a photo?
Thanks,
Tom

Tom,
Based on your response here, when you say "if a streambed consists mostly of sand and gravel while curving gently upwards at the end of a pool, it can be considered a hydraulic control"--our question is, should the sand/gravel slope following a pool always be considered a hydraulic control? We have the opposite question of the original post: Can you have a pool without a hydraulic control? (when there is no cobble or boulder boundary (or other barrier type) at the end of the pool)

A hydraulic control is typically only defined, or found, in relation to the formation or presence of a pool. In other words, you are unlikely to have a true hydraulic control (that creates a continuous, flat water surface elevation) without having a pool. If you have a pool, a hydraulic control is likely present, but it may be hard to determine the control type - cobble or boulders are easy to visually assess, but if a streambed consists mostly of sand and gravel while curving gently upwards at the end of a pool, it can be considered a hydraulic control, though it is harder to identify.
