Completed in 1953, the resultant [[reservoir]], the {{Title case|PINE TIER LAGOON}}, was established for the purpose of generating [[hydroelectricity]].
The Pine Tier Dam and its reservoir are one of several dams and reservoirs that supply water to the [[Tungatinah Power Station]], a [[Hydroelectricity#Conventional (dams)|conventional]] hydroelectric [[power station]]. The dam, reservoir and power station are owned and operated by [[Hydro Tasmania]].
== Dam and reservoir overview == From the Nive River, most of the water entering the Pine Tier Lagoon is diverted via the Bronte canal to the [[Bronte Lagoon]]. Only overflows from the Pine River Dam enter the river, below the dam wall.<ref>{{cite web |url=https://nre.tas.gov.au/Documents/Annual%20Waterways%20Report%20-%20Upper%20Derwent.pdf |page=4 |title=Annual Waterways Report: Upper Derwent Catchment |work=Water Assessment Branch.

=== Reservoir === The Pine Tier Lagoon is a popular site for inland fishing, with both [[brown trout]] and [[rainbow trout]] found in the lake.<ref>{{cite web |url=https://www.ifs.tas.gov.au/media/publications/Pine_Tier_Lagoon_A4_Fact_Sheet_2024_WEB.pdf |title=Pine Tier Lagoon: Anglers Access |work=Inland Fisheries Service, Tasmania |date= |access-date=2026-04-12 }}</ref>
North and west of the Pine Tier Lagoon is the Pine Tier Conservation Area, a {{convert|1914|ha|adj=on}} protected conservation area, part of the [[Tasmanian Land Conservancy]]'s Five Rivers Reserve, that links the area with the [[UNESCO]] [[World Heritage Site|World Heritage]]-listed [[Tasmanian Wilderness World Heritage Area|Tasmanian Wilderness Area]].<ref>{{cite web |url=https://tasland.org.au/reserve/pine-tier/ |title=Pine Tier |work=[[Tasmanian Land Conservancy]] |date=July 2025 |access-date=2026-04-14 }}</ref>
== Hydroelectric power station == {{main|Tungatinah Power Station}} The Pine Tier Dam forms part of the complex of several dams, including the Bronte Lagoon formed by Bronte Dam, Bradys Lake formed by Bradys Dam, Lake Binney and the Tungatinah Lagoon; and a tunnel, canals, pipelines, flumes their associated control gates and a pump station. Together, these reservoirs support the generation of electricity at the [[Tungatinah Power Station]], a conventional hydroelectric power station, situated adjacent to Lake Binney Dam.<ref name=hydro>{{cite web |url=http://www.hydro.com.au/energy/our-power-stations/derwent-0/tungatinah-power-station |title=Derwent: Tungatinah Power Station {{!}} Energy |work=[[Hydro Tasmania]] |date= |access-date=5 July 2015}}</ref><ref name=hydrotech>{{cite web |url=http://www.hydro.com.au/system/files/Tungatinah_Power_Station-Fact-Sheets.pdf |title=Tungatinah Station: Technical fact sheet {{!}} Derwent Catchment |work=[[Hydro Tasmania]] |access-date=5 July 2015 |url-status=dead |archive-url=https://web.archive.org/web/20150924032935/http://www.hydro.com.au/system/files/Tungatinah_Power_Station-Fact-Sheets.pdf |archive-date=24 September 2015 |df=dmy-all }}</ref>
