Program Changes and Updates. This sampling program has been in place with relatively few changes since 2009. The 2016 study plan presented a review of changes to the sampling plan that had not been captured in previous study plans. The reader is referred to that study plan for documentation of those changes. Changes made to the sampling programs and implemented in 2017 are discussed in the 2017 study plan. These changes were necessary to reduce program costs and bring the program back to the budget set in IM 15. There were no changes made to the 2018 program compared to 2017. Starting in 2016 and extending through mid- 2017, PacifiCorp conducted a comprehensive review of KHSA data from 2009-2015. One of the first steps in this process was to standardize site names, site identification codes, and site river miles. This standardization has been carried forward into this study plan. As a result there may be slight differences in site names or river miles when compared to study plans from previous years. All the data files from previous years however, have been updated with the consistent naming system.

In 2016 it was necessary to appropriate approximately $112,000 from other KHSA Interim Measure funds to cover increases in cost. The KHSA water quality monitoring group met via conference call on November 28 and December 2, 13, and 20, 2016 to discuss changes to this study design necessary to bring the program back under budget. The following changes were made as a result of these discussions:

In 2019, the analysis of microcystin congeners was eliminated at the Klamath River at I-5 Rest Area (KRIB) and the Klamath River South Slough (KRSS) sites. This was done because the information was not being used for public health analysis and there are growing concerns about anatoxin-a levels for which sampling and analysis is not routinely conducted. Therefore, samples from these two sites will be analyzed for anatoxin-a only. The sampling schedule for the KRIB site remains the same and the KRSS schedule is monthly from July through October. Analysis of samples for microcystin congeners at the Klamath River at Weitchpec (KR04350) baseline site was also changed to anatoxin-a analysis on the same schedule and baseline sampling protocols. Sampling protocols were not changed, just re-assigned to these sites as necessary to reflect a change from the baseline sampling program to public health sampling program, following the same approved protocol.
