An Irrigation Ditch Runs Through It: What property owners need to know

Water has been used for irrigation in Montana for over 150 years. Irrigation ditches flow across many Montana landscapes and play a critical role in providing water for agriculture. These ditches also recharge groundwater and wetlands, create wildlife habitat, and more. If a ditch crosses a property, it brings with it certain legal requirements and responsibilities. Ditches are more than just waterways — they are working agricultural infrastructure rooted in Montana’s property law and agricultural history. By understanding the legal foundations of ditches and water rights, and maintaining open communication, landowners can avoid legal entanglements and can help maintain good-neighbor relationships.
