Officers from west Cumbria alongside partners from the Lake District National Park and United Utilities are working together in a joint operation to tackle wild camping.
In recent weeks there has been an increase of wild campers and campervans on private land in the Lake District National Park which is illegal.
Those found camping could face a fine for breaching the regulations.
Partners will be carrying out joint patrols over the next few weeks in the Keswick and Borrowdale valley area and will be also targeting those setting fires and causing damage to the land.
Sergeant Scott Adams said: “As restrictions have begun to ease we have seen a number of wild campers in the Lake District National Park.
“It is illegal to camp without permission from the landowner and you will be asked to move on and could face a fine.
“During this current climate we are encouraging the public to plan ahead and respect local communities, there are many ways you can enjoy our area without causing damage or camping illegally. ”
Caroline Holden, Land Agent at United Utilities, added: “The reservoir catchment land at Thirlmere and Haweswater acts as the first stage of the treatment process for the clean drinking water we all rely on.
“If trees are destroyed and human waste and litter are left discarded it all has the potential to pollute our precious water resources, as well as being unsightly and dangerous for those enjoying the countryside.
“We welcome courteous day visitors but camping is not permitted. All we ask is that people follow the countryside code – cause no damage and leave nothing behind.”
