Michael (17 March 2021) in Stuff) was identified, a sense check recalculation was done and the non academic source was unable to be verified up to August 2023, as it implies a 30 m odd change in relative lake levels from the present. The sense check calculation took the following into account. GPS data since it has been available shows that this area of the Taupo Rift is sinking relative to the coast and this has remained linear for the last 16 years at NZ Geonet station RGTA on Mount Tarawera. It seems reasonable to assume that the outlet of Lake Tarawera and the land around the present Rotomahama has sunk at a similar rate towards a. s. l.. If this is not the case, then this predicts that between 1885 and 2016 one of the lakes, could have sunk up to 1.9 m relative to the other. Perhaps the most likely deviation, looking at other nearby GNS stations, is only 0.5 m but for sense check purposes the biggest possible difference was allowed as GNS rate of change data was not available for one estimate. GNS datum rate of change at all Bay of Plenty sea side locations is less than a tenth of the value inland and sea level change due to ice cap melting is also not likely to be significant in the calculation since 1886. An historic assumption that the old Lake Rotomahana level was about 2 m (6 ft 7 in) higher than Lake Tarawera, is likely incorrect as the difference is documented to be 12 m (39 ft) in a pre 1886 source. So as we have a disagreement of about 10 m difference in lake levels at the time of the eruption from these two sources different assumptions. What we have left to know is the relative change in lake level of Lake Tarawera. In 2005 Hodgson and Nairn did this working forwards from 1886. The relative change data for Lake Tarawera, is known, as initially its outlet was blocked by the 1886 eruption with the lake level rising by 12.8 m. The 1904 volcanic debris dam break dropped the level by 3.35 m and since then there has been minimal change. So we know that the 1886 level was 9 m lower than the current Lake Tarawera level but to this must add 1.9 m so the 1886 level was 7.1 m lower than present. The current lake level as of 2016 was 340 m of Lake Rotomahana, with a known difference in current lake levels between Tarawera and Rotomahana of 39 m. The sense check suggests the relative difference of lake levels historically as of 1886 was similar to this current difference and is within 5 m of the present value but the absolute heights above a.s.l. will have changed in over 100 years by about 2 m.
405:. After the eruption a new Lake Rotomakariri to its east briefly existed before being incorporated by lake level rise into the present lake. The now lake floor was mostly dry when surveyed in the period 1886 to 1888 after the eruption, and it is possible to match these observations with current geolocated hydrophonic findings. High quality pictures of the old Lake Rotomahana and associated tourist attractions were widely available in Europe by 1875. Following the eruption, a number of craters filled over the course of 15 years to form today's Lake Rotomahana. As a result it is the most recently formed large natural lake in New Zealand, and at 118 m (387 ft) deep, the deepest in the Rotorua district. The former official depth was previously 112.4 m (369 ft), at a lower lake level and with less precise equipment. The lake bottom currently has up to 37 m (121 ft) of sediments, which means the Rotomahana crater bottom is 185 m (607 ft) above sea level. 398:. In the context of the geological discussion it is important to note a high standard hydrophonic survey took place in 2016 and the actual absolute measurements taken at this time, as lake level varies, are used for geological baseline. At this time the lake level was 340 m (1,120 ft), not the geographically mapped height of 337 m (1,106 ft), or the mean height of 338.7 m (1,111 ft). Lake Rotomahana has no natural surface outlet, and its water level varies by about one metre in response to rainfall and evaporation. There is now an engineered surface channel to maintain maximum lake level. Hydrogeologic models of the catchments in the Ōkataina Caldera predict that the Lake Rotomahana catchment is contributing subsurface to the Lake Tarawera catchment with an outflow, depending upon the size of the catchments so defined, of between 1,125–3,018 L/s (39.7–106.6 cu ft/s). 770:
diameter) lakelet also known as Green Lake (Lake Rotopounamu) had existed to the north of Lake Rotomahana in Waikanapanapa Valley but this was exhumed during the Tarawera eruption. After the eruption, water flowed into the new Green Lake crater, which was given the same name as the older lake. Other pre-eruption lakes and lakelets about Lake Rotomahana included Lakes Rotomakariri, Rangipakaru, Ruahoata and Wairake. The shape, location and orientation of Lake Makariri in Cole, 1970 (cited herein) is incorrect. He followed August Petermann's flawed map. Hochstetter shows the lake axis lay at an azimuth of 355 degrees. Recent research into these lake levels gave insight into changes at Lake Rotomahana in the lead-up to the eruption.

Using Hochstetter's field diaries and compass data, a team of New Zealand researchers identified a location where they believe the Pink and White Terraces lie preserved at a depth of 10–15 metres (32–49 ft). The researchers were hoping to raise funds for a full survey of the area, but any work would first have to be approved by the local 54: 412:, separated by less than 700 metres (2,300 ft) of terrain that is mostly material from the 1886 eruption. The original Lake Rotomahana has a slightly controversial level with respect to that of Lake Tarawera before 1886, partially because the eruption also changed the level of Lake Tarawera and there was a later lowering of Lake Tarawera's level around 1904. 786:
