The city of Oklahoma City has recently turned a herd of nearly 20 goats loose along the Hefner canal to help with clearing brush.
The goats came from Langston University in an effort to save the city money.
Monte Hannon with Oklahoma City Water Quality says they have the goats for 6 months, and using them will cut the costs of diesel and reduce the use of chemical weed killer.
He said the equipment that is normally used to cut grass cannot get out on the steep slopes surrounding the canal. Instead, they would have to use an extended boom mower which can be expensive and difficult to maintain.
A guard dog will be used to protect the goats and a fence is surrounding the canal to prevent the goats from wandering onto people's property.
The city will use the goats permanently if the project works.
