Keepit Dam is a major gated mass concrete gravity dam with an earth fill abutment and a central gated concrete overflow crest and six radial gate spillways across the Namoi River upstream of its junction with the Peel River in the North West Slopes region of New South Wales, Australia. The dam's purpose includes flood mitigation, hydro-power, irrigation, water supply and conservation. The impounded reservoir is called Lake Keepit.
