South Columbia Basin Irrigation District (District) has long been interested in pumping water from the Esquatzel Diversion Canal (EDC) into the Pasco Pump Lateral (PPL). The EDC and the PPL cross each other just east of where the EDC returns project waste, seepage and return flows to the Columbia River. The PPL receives water from the tail end of the Potholes Canal, serving Block 1, and frequently would face water shortages during peak demand.
