The Problem with Phosphorus
Phosphorus enrichment of waterbodies negatively impacts water quality. The accumulation
and internal recycling of phosphorus in waterbodies has significant and lasting
impacts on the aquatic ecosystem, drinking water supplies and recreational uses.
In addition, excessive phosphorus levels can result in regulatory implications due
to exceeding of total maximum daily load (TMDL) thresholds and state and/or federal
water quality standards.

Watershed Management Isn’t Enough
Proactive waterhshed assessment and management actions are an important best management
practices to reduce the level of phosphorus entering waterbodies. Even
when external sources of phosphorus have been curtailed by watershed management
practices, the internal recycling of phosphorus in waterbodies can continue to degrade
water quality and have lasting impacts on the aquatic ecosystem. 'In-Lake' phosphours mitagation
is a critical componet of an integrated approach to restore impared water bodies.
