9 Comparison to UGS data
The patterns of salinity and Gilbert Bay elevation observed in Figures 7.1 and 7.2 and 7.3 are also consistent with those from an independent dataset provided by UGS (Figures 9.1 and 9.2).
This dataset includes a longer time series of density data from a wider range of lake elevations. It also demonstrates that in addition to the changes observed following the breach opening, the conditions observed in both the pre (2010 - 2016)
breach and post (2017 - present) time periods are likely different from historical observations (Figure 9.1).
