The announcement was made through the Nicoya Municipality facebook page. The work was done through the risk management department; they claim to have made a thorough cleaning of the Nosara river in the sectors of Rancho Rico, Aeropuerto and Santa Marta. We assume that they made a simple typing error and meant to publish “Racho Tico”. They say the work was done in preparation for the coming season to make the area generally safer.
Here’s a photo of the same river from 2017 that was published in an article by crhoy.com.
