Young muskrats grow rapidly and are independent at an early age. Although muskrat feeding habits may damage agricultural or ornamental crops growing near water, the principal concern is potential damage to earthen water-retaining structures. Extensive tunneling into earthen dams may cause water leaks or the loss of stored water. Burrowing damage occurs most often in older ponds where the dike is thinner from erosion or is poorly designed. Trees growing on the dike sometimes create problems attributed to muskrats.
Tree roots die, and water follows the roots until the dike gives way.
Since it is easier to deal with a population of muskrats before they have become established, watch for signs of their presence and adopt remedial measures as soon as possible. Landowners should watch dams closely for burrows and repair weak spots at once. It is relatively easy to fix a weak spot, but it is a big job to repair the dam after it is broken. Law and Regulations Muskrats are classified as furbearers in Kansas. Licensed fur harvesters may take muskrats during the regular fur-harvesting season.
