Seqwater will undertake geotechnical drilling investigations near the spillway at Lake Macdonald as part of planning and design for the dam upgrade. These investigations will help us to better understand the rock and soil characteristics beneath the dam to assist in the Dam Improvement Program upgrade. 

Work will start on Monday 22 May and take about six weeks to complete, subject to weather conditions and other unexpected delays. Working hours are between 7am and 5pm, Monday to Saturday. Equipment will include, but is not limited to, a drilling rig mounted on a barge, trucks and utility vehicles. There may be an increase in noise, dust and traffic during this period, but we will try to minimise disruptions where possible.
