Advanced Phytoplankton Ecology

Tuesday, October 30
8:00 am – 5:00 pm | $215

This workshop explores the complex interactions that regulate the growth, distribution, and productivity of phytoplankton in lakes. With the increasing predominance of cyanobacteria in lakes around the world, understanding the concept of a lake as a home to these organisms is more critical than ever before. Examples from literature and case studies will be used to build the structure of the lake home starting with properties of water, (density, viscosity, redox, pH, light, oxygen and dissolved gases, and carbonate magic). Definition of properties will be followed by examination of the motions of water in lakes and how it is the master variable that regulates distribution of plankton (convection, turbulent flow, density gradients and stratification and water column stability). The aspects of water and motions are combined to provide a framework to review the different strategies that phytoplankton have adopted to remain in the water column (gravity, sinking, form resistance, density alteration, and vital sinking rates). The topics of growth rates and productivity will be covered briefly to provide context on how the phytoplankton community is forced to undergo seasonal succession due to changes in light, heat, nutrients, stratification, mixing and grazing. The workshop will conclude by describing how buoyance regulation allows cyanobacteria to take advantage of lake structure and dominate the plankton and develop surface blooms.

Alum for Phosphorus Control in Lakes and Ponds

Tuesday, October 30
8:00 am – 5:00 pm | $215
Sponsored by HAB Aquatic Solutions

Alum (aluminum sulfate) is widely used for controlling phosphorus (P) in lakes and ponds. There is a large body of knowledge and wide experience using alum due to its efficacy, safety and cost-effectiveness. This workshop provides a systematic overview of the planning, diagnostic, monitoring, dosing and application technologies for using alum for P control. Alum use strategies for deep and shallow lakes include a) water column P stripping, b) P interception, c) maintenance dosing, d) sediment P inactivation and e) P control in ponds. We provide overviews of the history of alum use, long-term efficacy, aluminum chemistry, diagnostic and modeling tools, a decision matrix for the appropriate alum use strategy, dosing calculations, application technologies and monitoring requirements. As well, we provide updated information on other P precipitants and compare/contrast costs, efficacy, reliability, etc. We will discuss numerous case studies and welcome participants to present their lakes’ concerns. The workshop is interactive and there is ample time for discussion.

Internal Phosphorus Loading

Tuesday, October 30
8:00 am – 5:00 pm | $215

Internal phosphorus loading as phosphorus (P) released from anoxic sediment surfaces often represents the main summer P load to lakes. Because of its high biological availability, the lack of dilution, and the timing, it can have an immense effect on summer water quality of a lake, reservoir, or pond. However, depending on the stratification of the lake, it is not always easy to determine the quantity of internal load (especially in polymictic lakes), and it may be difficult to estimate the ultimate effect it may have on surface water quality (especially in stratified lakes).

This workshop presents a way of quantifying internal load in polymictic as well as stratified lakes. Considering lake characteristics and data availability, such quantification can be done in a step-wise fashion, where missing data may be predicted by subsidiary models. After the mere quantification of internal load, the participant will learn how to combine it with external load in a simple mass balance model to predict seasonal phosphorus concentration. Knowing this, other water quality characteristics (algal biomass, bloom frequencies, Secchi disk transparency, and hypolimnetic anoxia) can be arrived at. Applications regarding lake quality assessment, nutrient criteria, total maximum daily load (TMDL) computations, and restoration options will be discussed.

Each workshop topic will include a description of the theory and presentation of case studies covering US, Canadian, and European lake assessment and restoration projects. Open discussion with attendees is encouraged, and comprehensive handouts and references will be provided. For preparation, see publications listed at www.fwr.ca, especially Nürnberg GK. 2009: Assessing internal phosphorus load – problems to be solved. Lake Reservoir Management 25:419–432.

Lanthanum Modified Bentonite – Dosing, Ecotoxicology and Modelling

Tuesday, October 30
8:00 am – 5:00 pm | $100
Sponsored by Phoslock Water Solutions

Lanthanum modified bentonite (LMB, commercially known as Phoslock) is being increasingly used to immobilize phosphate in eutrophied lakes and reservoirs, thereby mitigating against the risk of cyanobacterial blooms. It is a highly efficient phosphate binder due to the strong affinity of lanthanum (La) for oxyanions such as phosphate. This workshop will provide participants with a brief introduction to Phoslock, explaining what it is, how it is being used and what its strengths and weaknesses are. Tutorials relating to dosage calculations and ecotoxicology will be conducted, followed by an explanation of chemical equilibrium modelling (Cheaqs Next). Participants will be given the opportunity to run their own modelling scenarios using free available software which can be provided and installed in advance.

The Role of Aeration/Oxygenation in Lake Management

Tuesday, October 30
8:00 am – 5:00 pm | $215

Addition of air or oxygen is frequently used as a lake management option for lakes suffering from oxygen depletion. When used properly, aeration/oxygenation can increase oxygen concentrations in the water column, decrease sediment nutrient release, minimize iron and manganese concentrations, and prevent fish kills. These systems can be designed to provide complete mixing throughout the water column, to increase oxygen concentrations in the hypolimnion without mixing the lake, or to aerate surface waters and provide aesthetic appeal. Improperly designed or installed aeration systems can increase algal growth and lead to decreased water clarity. The workshop will discuss the pros and cons of aeration systems, describe factors that must be considered to properly design aeration/oxygenation systems, and present case studies for both successful and unsuccessful applications.
