Despite persistent rain, and the cancellation of the festival's live concerts, more than 200 people still turned up in wet weather gear to enjoy the other festivities at Chingford Park.
Valley Project community development and event co-ordinator Anna Parker said more than 20 community organisations voluntarily supported the event, by providing various activities.
Among the most popular were the Discovery Walk, and Fish and Game regional field officer Steve Dixon's demonstration of electric fishing.
Mr Dixon used a direct current of electricity, flowing between a submerged cathode and anode, to force fish in the stream to swim towards the anode where they were caught with a net, allowing people to see all the life in Lindsay Creek.
Stalls with displays about how to care for Lindsay Creek were created by Opoho, Dunedin North Intermediate and Northeast Valley Normal Schools. The Dunedin Youth Council also encouraged young people to write down ideas for caring for the Dunedin environment, to be presented to the Dunedin City Council.
Ms Parker was surprised at the turnout.
''We had to cancel the music festival part. I am delighted to see so many people have come, just for the education events.
''I think it says a lot about the Northeast Valley community - we're a close community and we care about each other and we love celebrating together.
''It also says a lot about their passion for the environment and the health of the stream.
''This creek is the life-blood of the valley ...''
