Irrigation ditch burns scheduled for this spring.

Boulder County, Colo. - The Boulder County Fire Management Program will conduct irrigation ditch and agricultural burns on county open space lands this spring as conditions allow.

Irrigation ditches are burned to remove unwanted vegetation for improving water conveyance, nutrient cycling, and planting success. Burn dates are contingent on ideal weather conditions, including relative humidity, fuel moisture, and wind.

Boulder County Parks & Open Space irrigation ditches and agricultural properties scheduled for controlled burns this year include:

  • Jim Henry (N. 115th St. and Niwot Rd.)
  • Gaynor Lake (N. 107th St. and Oxford Rd.)
  • Wittemyer (N. 119th St. and Mineral Rd.)
  • Leggit Ditch (E. Countyline Rd. and Oxford Rd.)
  • Marfel Lakes (N. 119th St. and Arapahoe Rd.)

There may be heavy smoke in the air. Please do not call 911 since a ditch burn is not an emergency. The areas will be monitored to ensure fires are completely out.

Smoke from prescribed fires may affect health. The Colorado Department of Public Health & Environment Wood Smoke and Health website and the Boulder County Public Health Wildfire Air Quality & Health website provide tips on how to protect health from smoke.
