People are being asked to help shape plans to protect and improve the health of waterways.
Natural Resources Wales (NRW) has launched a public consultation on the future management of rivers, lakes, streams, groundwaters and coastal waters.
The consultation will remain open until April 21, 2026, and forms part of the development of updated River Basin Management Plans, which are revised every six years to guide action and policy.
Dr Rhian Thomas, sustainable water and nature manager at NRW, said: "Our waters are under increasing pressure and threat from climate change and human activity.
"In recent years we have seen action at scale, by ourselves and many other organisations, to tackle some of biggest challenges causing pollution, poor water quality and habitat decline.
"But this is an opportunity for anyone who cares about the future health of our waterways to let us know what challenges and issues they see out in their local area, and to be part of the solution."
The plans cover all types of water bodies and set out actions needed to meet statutory standards.
NRW will develop River Basin Management Plans for Western Wales and the Dee River Basin Districts.
The Severn River Basin Management Plan, led by the Environment Agency in partnership with NRW, will open for consultation later this year.
Those wishing to take part can find details on NRW's website.
Paper copies are available by emailing [email protected] or calling 03000 65 3000.
NRW has also published an interim progress report on the current River Basin Management Plans (2021-2027).
This report reviews progress on planned actions and outcomes for water bodies across Wales.
Dr Thomas said: "Developing the next set of River Basin Management Plans provides us with an opportunity to set new ambitions for managing our waters in Wales."
