[edit] Geography

The Mokihinui River's headwaters are located in the Glasgow Range and its mouth is on the Tasman Sea. There is little human habitation near the river: the localities of Mokihinui and Summerlea are near the river's mouth, Seddonville is a few kilometres up the river, and just prior to its terminus, State Highway 67 crosses the river outside Mokihinui. In the rugged back country behind Seddonville at the Mokihinui Forks, the river splits into two branches, north[2] and south.[3] The catchment of these two branches is a large inland basin of almost wholly unmodified forest.[4]

[edit] Railway

The last few kilometres of the former Seddonville Branch railway roughly followed the Mokihinui River near its mouth. The Branch opened on 23 February 1895 and closed on 3 May 1981.[5] During this period, the New Zealand Railways Department dumped old steam locomotives on the river's banks to protect against erosion. Two of these locomotives, members of the WB class, were recovered from the Mokihinui River in 1989 by the Baldwin Steam Trust.[6]

[edit] Hydroelectric dam proposal

Meridian Energy is proposing to build a hydroelectric dam on the river to produce 310-360 GWh per year. In 2007, it consulted affected parties about the proposal.[7] The dam would be located 3 km upstream from Seddonville, between it and the Mokihinui Forks. Meridian Energy began investigating the proposal in 2006, following from similar studies conducted by the New Zealand Ministry of Works in the 1960s and 1970s.[8] On 15 March 2008, the West Coast Regional Council called for public submissions on Meridian's applications for resource consents. Submissions may be lodged until 23 April 2008.[9] The application for resource consents and 18 appendices of assessments of effects are available from the Meridian website.[10] The Royal Forest and Bird Protection Society are opposing the dam and have accused Meridian of not making public a report from Landcare Research that advised that the hydro scheme would cause significant adverse environmental effects.[11]

Meridian energy has suppressed a report by its own scientists that condemns the proposal, saying that the adverse effects on the environment and endangered native species "cannot be mitigated".
