The Malloy Drain Basin drains through a complex series of natural and constructed canals and drains. The main drain runs through the Town of Coaldale. The drainage channel has limited capacity. The committee consisting of the Town of Coaldale, Lethbridge County and SMRID retained MPE to look at cost options for a range of storage and release options, varying from 0.5 L/s/ha with significant storage, up to 4.0 L/s/ha with very little storage. Existing ‘natural storage’ and ponding areas have been included in the analysis, as well as constructed pond facilities.
