People are being asked for their views on how England's longest lake should be managed.
The Lake District National Park Authority (LDNP) and South Lakeland District Council are working on the Lake Windermere strategy review.
They want to know what residents and visitors want from the 10.5 mile (17 km) stretch of water.
The consultation will run until the beginning of October and people can take part online.
LDNP's water projects coordinator Suzy Hankin said that the lake was special for many reasons.
"The stunning scenery and cultural and recreational opportunities are there for us all to enjoy," she said.
"The existing management plan has been in place since 2005 and there have been many changes since then.
"We have produced a draft review to update the document for 2010 to 2015 and want to test opinion.
"I would urge everyone who has something to say about our world famous lake to get in touch."
