Adyanpara Weir is a small diversion dam constructed across Kanjirapuzha River at Adyanpara in Chaliyar panchayath of Kurumbalangode village in Malappuram district of Kerala, India. This weir is a part of Adyanpara SHEP, which envisages development of power by utilizing the potential of Kanjirapuzha stream, a tributary of Chaliyar river. It consist of a diversion weir, desilting chamber of splay type, power tunnel of length 968.50m, an underground surge tank in circular shape. The 3.5 megawatt hydroelectric project has been setup as part of the Small Hydro Electric Project. The water from the weir flows to Kanjirapuzha through the Taluk of Nilambur. The dam is a concrete-gravity type dam with a height of 5.56 m and a length of 58 m.

Hydro Electric Project
The Powerstation is in the downstreams from the weir. Water from the Weir flowed through a tunnel which is 976 meter long to a forebay Tank. Water is then channeled through a Penstock pipe to the Power station where there are 3 Generators installed. A total of 3.5 Megawatt Electricity is produced using these 3 generators.

Hydel Tourism
Kerala State Electricity board has set up Hydel Tourism around the Power plant and the dam. Board arranges conducted tours where tourist can have ring side view of the power plant.
