At Mayannur, Gayathripuzha merges with the river. The

watershed of 6,186 km

Some of the famous persons cremated here include literary personalities like O V Vijayan and VKN.
Degradation
The river went through a series of challenges which saw its degradation that has reached a point of no return. The erratic, non-conservative attitude of people has resulted in much of its water becoming not potable.
Until a few decades back, the river used to flow effortlessly during even intense summer. However, due to the
sand mining in the last 30 years, the thick sand bed has been completely vanished and has then been replaced with
grass
Poaceae ( ), also called Gramineae ( ), is a large and nearly ubiquitous family (biology), family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos, the grasses of natural grassland and spe ...
es and
bushes which has become an environmental catastrophe.
At the peak of the sand mining period in the mid 1990s at least 40–50
lorries carrying tonnes of pristine sands were a common sight at each 'kadavu' (entrance to the river) of the river. Considering the hundreds of 'kadavu' throughout its length, the amount of sand mined in these years is unimaginable. Today, with almost no sand in many parts of the river, people have started mining sand from underwater which has become a profitable business for many. Significant changes in the climatic pattern also altered the flow pattern in the river. Studies reported that there is a significant dip in the total annual rainfall
and significant increase in the annual temperature in the basin.
Challenges

The river now faces significant challenges for its survival. It is predicted that the river may change its course due to the obstruction of the tall grasses and bushes that has grown in the river.
Illegal sand mining mafias are very active and the nexus between the politicians, bureaucrats and these mafias make it extremely difficult to stop this. Organisations which were once very active have now gone on hibernation due to the threat posed by them. Environmentalists have predicted dire consequences and the untimely death of the river within the near future. The wastes from the hospitals and other sources pollute the water.
Social networking sites like Facebook have active groups with a purpose of saving the river named as Bharathappuzha Samrakhshana Samithi.
Friends of Bharathapuzha, a nature lovers' collective, is being formed with the objective of strengthening and protecting the Bharathapuzha. It is led by E.M. Sreedharan, veteran engineer popularly known as 'Metroman'.

suggest the followings actions for saving the river.
* Controlled mining of the sand if not completely stopping it. Sand beds which got created in millions of years were completely removed within a few years of human greed and mismanagement. Creation of sand is a very slow process and is considered as the veins of the river. Although a total ban is impossible and impracticable, strict regulations needs to be put in place for sustainable mining of sand. Experts suggest that a portion of the revenue from sand mining has to be allocated for river management.
* Strict regulations for hotels, hospitals and households on managing their waste. Regulation has to be put in place and enforced for managing waste generated by hospitals and hotels.
