3.0 DESCRIPTION OF PUKETIRINI3.1 Current usesPuketirini is utilised by the public regularly for off-water recreational activities, such as walking, running, and cycling. Asignificant number of community activities have also taken place at this site.Lake Puketirini was opened for on-water recreational activities between March and May 2007. Lake access was grantedby way of a key system to control user access to the lake. The purpose of this trial was to determine what issues mayoccur when allowing recreational activities on the lake. Lake Puketirini has been re-opened for public use in 2007/08 and2008/09 between November and May, re-utilising a key system.The New Zealand School of Commercial Diver Training regularly uses the lake. It is considered an ideal location fordiver training due to the lake’s depth and water quality. The diving school has a commercial agreement with Council.Part of Puketirini is leased to Wel Networks Limited for substation operations located within the park boundary.The Waikato Coalfields Museum has placed the Huntly Railway Station building at the Puketirini as part of plans torelocate Waikato Coalfields Museum to the park.3.2 Lake water qualityWithin the Waikato District, the lake is unique due to its high water quality. Monitoring at the lake and western drain hasbeen undertaken on a quarterly basis since 1996. The pH level within the drain has decreased approximately one unitbetween 1996 and 2007.The extreme depth of the lake compared to its small area means mixing of the water column is poor. As a result thewaters below 20 metres or so may be semi-permanently devoid of dissolved oxygen. Fish and other organisms areunlikely to be present in oxygen depleted waters, and there is a risk of contaminants being released from the bottomsediments into the overlying water. The lake is probably still coming to equilibrium (i.e. “settling down”). Recent researchsuggest the lake’s water quality may decline somewhat as it approaches equilibrium.To provide a comparison of water quality between Lake Puketirini and other lakes within the Waikato region, LakePuketirini water quality is better than that at Lake Waahi, but is of lower quality than Lake Taupo. Lake Puketirinicontains higher concentrations of phosphorus and algae, and the waters are less clear. It is classified as “mesotrophic”(Balvert, 2006).The following table provides annual average water quality in Lake Taupo, Lake Puketirini, and Lake Waahi:1Table 1: Total phosphorous, chlorophyll a and secchi depth within Lake Taupo, Lake Puketirini, and Lake WaahiLakeTaupo2 3LakePuketiriniLakeWaahiTotal phosphorus (mg/m3) 6 12 80Chlorophyll a (mg/m3) 1 3.5 74Secchi disc depth (m) 15 4 0.41 A mesotrophic lake contains a moderate amount of nutrients.
