This is a riverside festivity in honor of St. Anne, Patroness of Agusan River. Highlighted by Baroto Races and indigenous games for men, women and children, capped by a Fluvial Parade.

According to the History of Christianization of the Dioceses of Surigao and Butuan prepared by A.H. Van Odjik, M.S.C. (p.103), the Feast of Santa Ana usually held in the latter part of the month of July is a fluvial procession, which is held every year as the main attraction of the day. This feast was celebrated as early as 1886 and had been thought of and implemented to obtain a safety against the crocodiles which then infested the river.

It should be remembered that Butuan River during the early 17th and 18th century was infested with man-eating crocodiles. It was unsafe to travel, especially at night, in any part of Butuan River due to the presence of these numerous crocodiles to attack them while paddling their barotos.

When these dangers reached the ears of the local parish, the priests took immediate steps by proclaiming to the people that the appearance of these crocodiles along Butuan River was the working of the devil and that the only remedy was to seek the miraculous aid of the venerated Santa Ana, who had the power to drive the demons of the river. The priests asked the people to unite for the common cause by bringing Santa Ana into the river where it is infested with crocodiles so that they could obtain safety if they all prayed and have faith in the divine works of Santa Ana. The people responded and decided to form a unique organization called as "Mag Abayan Kita" as a day of devotion and Feast for Santa Ana.

Before the day of the fluvial procession, leaders of the different barangays joined hands to make the affairs a success. They secured ten big boats (Kayahan) and linked them altogether with pieces of split bamboos to serve as the platform for the altar of the statue of Santa Ana, and was made spacious enough for the priest, a choir and several attendants during the performing of the rites. It was well-decorated with red banners, leaving two boats on the left and right side for the rowers to to propel the floating platform as it goes down and up the river during the fluvial procession. Then over a hundred decorated barotos participated in by the inhabitants settling along the river banks row around the moving platform chanting and shouting all the way the words "Viva Seņora Santa Ana."

On the appointed day of the Feast of Santa Ana, the participants in their usual wet clothers, bringing along their paddies, attend a special High Mass to commence the traditional "Mag Abayan Kita". After the offering of the mass, the statue of the miraculous Santa Ana is borne on the shoulders of the people to be brought to the platform prepared for by the occasion. All the residents of Butuan deserted their homes to go to the river bank to watch this colorful fluvial procession. As soon as the statue of Santa Ana is placed on the altar, with the officiating priest and its choral group around, the floating platform is rowed away from the old wharf up to the old site of Butuan Public Hospital and from there it slowly floats down up to the mouth of Ba-an River and returns to the old public wharf.

Thundering shouts of "Viva Seņora Santa Ana" echoes loud and clear as the fluvial procession moves on. The chanting of the choral group, coupled with the timing of the agong beats drives the Butuanons into a state of frenzy and passion as they rowed past one another exhibiting their expertise of padding along the river, crackling their paddies now and then as they kept circling the moving floating platform, some are accidentally capsized capping the day's event with colorful pomp and glory. The maddening rush to get near the statue of Santa Ana adds spectacle and excitement in the traditional "Mag Abayan Kita". Men, young and old, women as well, participate by shouting at the top of their voices praying for the deliverance and safety from the crocodiles that infest the river.
