Cootapatamba Hut was constructed by the Snowy Mountains Authority c1952 as an emergency shelter for hydrologists monitoring stations on Cootapatamba Creek — which in the early stages of the Snowy Mountains Scheme was proposed to be diverted through aqueducts and tunnels to supply a ‘Kosciusko Reservoir’ on Spencers Creek near The Chalet.
The CSIRO Rabbit Research Hut was built in 1964 as accommodation for researchers investigating the effectiveness of the Myxomatosis biological control upon rabbits. Rabbits were trapped, marked and observed in their warrens from a number of hides around a study area overlooking the Gungarlin River. The Snowy Plain study site was one of four used in these tests, and remained in use up to 1980.
Derschkos Hut was constructed by the Snowy Mountains Authority c1960 as an emergency shelter for hydrologists monitoring precipitation, snow depths and stream flows across the headwaters of the Tumut and Tooma Rivers after two men became trapped in an oversnow vehicle for 3 days during a blizzard.
