Muskrats are found across the state and are typically found near permanent water sources such as lakes, wetlands, rivers, streams and other water bodies. They are active year-round and can be found swimming in the water throughout the day. Muskrats can build small lodges out of aquatic vegetation or dig into banks for a den. Once the ice forms, muskrats swim below the ice and live in their lodges or huts throughout the winter months.
