Has anyone found a safe, practical way of raising the pH level so this doesn't happen?

The river was tested in 2009 and had pH levels of 7.6.

Overall, several species were distributed more or less based on the pH level.

The pH level of a basic solution is higher than 7.

Other plants may struggle to survive in these pH levels.
