Firefighters were called a Lake District reservoir on Saturday afternoon following reports of illegal camping and campfires.
Crews from Shap Fire Station and Penrith Fire Station were alerted shortly before 5pm.
Cumbria Fire and Rescue Service was told that a group of youths, believed to be camping in the Haweswater area, were gathering wood and burning it.
On arrival at he reservoir, there were no signs of smoke, Shap Fire Station said but firefighters filled backpacks with water and set off on foot to search the wooded area.
The crew met area wardens while walking, who confirmed the youths had been asked to leave and the campfire had been extinguished.
Shap Fire Station said: “The crew continued to check the area and once again speak to people illegally camping and educated them on the dangers these irresponsible actions could cause to the area.
“It was evident to see that many more camp fires had been burning at different times recently, as well as the use of barbecues.
“Wardens regularly check the area for people camping and lighting fires. They can and have imposed fines on people carrying out such activities.
“As a service we urge people not to use naked flames, light camp fires or use barbecues while enjoying our upland areas, especially while we are experiencing lengthy periods of hot and dry weather.
“Please always take away what you bring with you also.
“Access to upland areas throughout Cumbria can be very difficult and any kind of fire that gets out of control has the potential to use up significant numbers of resources for prolonged periods making it more difficult for us to attend other incidents which may be life-threatening.”
