Dr Ralph Ogden, ‘Lessons learned for solving the ACT’s water quality problems’

You are here

Thursday, 23 November 2023 - 12:30pm to 1:30pm

The Healthy Waterways program has been running since 2014 with an aim to improve water quality in the ACT’s waterways. It is best known for building ponds, wetlands, raingardens and other ‘nature-based’ and ‘water sensitive’ infrastructure that treats polluted stormwater in suburbs. However, the program has also funded a lot of research into water quality problems and solutions, and has recently expanded into the rural waterways. So what has been learnt and what are the prospects for making material changes to waterways in the ACT? This seminar will outline lessons learned and provide pointers to how the ACT Government hopes to tackle problems like blue-green algal blooms in lakes and ponds and sand slugs in rural rivers.
