Phosphorus Loading

Understanding Internal Phosphorus Loading from Lake Sediments by Patrick Goodwin, M.S., CLM Internal phosphorus (P) loading from sediments can represent a major driving force behind harmful algal blooms (HABs) within many lake systems. Understanding when, where, and...

Desired Oxygen Levels

What are the Desired Dissolved Oxygen (DO) Levels in Water by Patrick Goodwin What are the Desired Oxygen Levels in Water and is Too Much Oxygen Bad? Oxygen is arguably the most important water quality parameter governing overall lake health. It’s required to sustain...

Groundwater

Groundwater – making the invisible visible by Deborah Lee What is groundwater? When rain falls on the ground, the water does not stop moving. Some of the water flows along the surface and ends up in streams, lakes, and ponds. Some of the water is taken up by...

Hydrodictyon

Hydrodictyon; What It Is and How to Treat It by Deborah Lee Hydrodictyon 100x (m) The nets of Hydrodictyon still look like nets even if they are small, released colonies. Each cell is connected to two other cells at the ends to form a network. 100x (m) far-red...

Manganese in Lake Water

What is manganese oxide? Manganese is a common, naturally occurring mineral in rocks, soil, groundwater, and surface water. General forms of manganese in the environment are referred to as manganese (Mn)oxides. There are more than 30 Mn oxide minerals that occur in...

Pond Turnover & Oxygen

How does a lake receive Oxygen? Lakes receive oxygen from the atmosphere and through photosynthesis. Atmospheric oxygen is added from wind moving across the surface area of a lake. With more wind, more oxygen is added to the lake from the atmosphere. However, as...

All Things Harmful Algae Blooms (HABs)

What constitutes a Harmful Algae Bloom (HAB) Any concentration of algae that causes impacts to an aquatic system that can be documented as hazardous to human or ecological health. Algae is a broad term, and includes cyanobacteria, members of the chlorophyta (greens),...
