Options for addressing P-enriched sediments in lakes: A literature review

Abstract

The release of dissolved phosphorus (P) from lake sediments is currently considered to be the primary driver of excessive cyanobacteria growth in Te Roto o Wairewa/Lake Forsyth in Canterbury. The cyanobacteria blooms that routinely occur between spring and autumn each year limit recreational access to the lake, pose a hazard to animals and public health, and adversely affect ecosystems and cultural values.
