BLM Notifies Public of Harmful Algal Blooms within Río Grande del Norte National Monument

TAOS, N.M. – The Bureau of Land Management Taos Field Office is notifying the public of changing conditions related to harmful algal blooms along sections of the Rio Grande within Río Grande del Norte National Monument. No illnesses to people or pets have been reported, but visitors should make informed decisions when in or around the river.

Blue green algae occur naturally in the river, especially during warm and low water periods, but some blooms can produce toxins that may affect people and pets. Symptoms from exposure can include irritation of the skin, eyes or respiratory system, and in rare cases, impacts to the liver or kidneys, or death. Additional information about HABs and safety guidance is available through the New Mexico Environment Department’s online resources.

Based on current conditions, BLM is recommending increased caution for recreation users in specific locations along the Orilla Verde stretch of the river; especially visitors with dogs or young children. Updated safety notices are posted at river access points where additional care is advised. Visitors should be mindful of visible algae and avoid direct contact with affected water.

BLM staff will continue weekly HAB monitoring along the river from the Colorado state line to the Embudo, N.M. area and will promptly update the community and post signs where increased caution is warranted based on changing conditions.

If you suspect a HAB-related illness in a person or animal, including livestock, call the New Mexico Poison Information Center immediately at 1-800-222-1222 or the New Mexico Animal Illness Assistance at 1-888-426-4435 or take your dog to the vet immediately.
