Cham Dam was constructed from 1982 to 1990 through direct labor by the authority.
The primary concept was flood control to protect Gombe/Yola highway from perennial flooding. After an in house feasibility studies the Authority incorporated water supply and small scale irrigation of about 200ha.
The Dam embankment overtopped and breached a section of about 200m out of a total length of 1300m in 1998 as a result of inadequate Spillway capacity.
Contract for the reconstruction of Cham Dam and Irrigation Project was approved by ministerial tender's board then awarded to M/S Ceylon Construction Services Ltd in December 2011 at the total contract sum of N832,963,424.06 with a completion period of Eighteen (18) months.
However, due to budgetary constraints, the project initial completion period could not be met. Consequently, an Eighteen (18) Months extension was granted to the Contractor in November 2013 and this extension elapsed in April 2015.

Furthermore it should be noted that delays in Project implementation and the escalation of basic rates of works items necessitated an upward review of the contract with an additional sum of N32,830,828.41 in FY2015 by the Bureau of Public Procurement (BPP). Furthermore, in the year 2017 another cost review (RETC) was submitted to federal executive council through federal ministry of water resources for final approval to a more realistic project cost.
