It follows the discovery of an algal bloom last month, which closed the lake.
Lake Hood water quality task force chairman David West said several options were being trialled "to eradicate the bloom properly".
"There is no quick fix for algal blooms but we are working hard behind the scenes to ensure every idea is researched thoroughly and we have the appropriate specialist advice to support us."
Ideas included bringing in an aquatic harvester to remove weed building up in parts of the lake, introducing aeration in the canals through diffusers and looking at inputs which could remove nutrients from the lake.
The task force was made up of representatives from the Ashburton Aquatic Park Charitable Trust, Huntingdon Park Property Owners Association, Lake Hood Extension Project and the Ashburton District Council.
The group had been liaising with the relevant authorities, including Environment Canterbury and Te Whatu Ora Health New Zealand, and consulting experts since March last year.
Unfortunately, some hot days had not helped the situation, nor had comments on social media criticising a lack of action, Mr West said.
"The [main] task force is made up of ... volunteers who have been working over the New Year to address the algae issue with council’s support.
"Rather than engage on social media, we prefer people approach us directly and we can meet and discuss ideas in person.
"Already, many residents living in the Lake Hood community have helped by offering practical support and ideas, machinery and labour.
"We want to make sure Lake Hood remains a premier recreational destination for visitors and locals.
"Algae blooms in lakes are becoming more prevalent worldwide and they are complex beasts to solve.
"The task force is taking this seriously and wants to set up the lake for success."
