What does the label beta release indicated about a river?

A beta release in the context of a river typically indicates that the flow or discharge of water is being adjusted or released during a specific period, often for ecological management or hydrological studies. This label suggests that the release is part of an experimental or preliminary phase, where data is being gathered to assess its effects on the river ecosystem. It may also imply that the parameters of the release could be subject to change based on ongoing observations and feedback.
