The Reason Behind Lake Tahoe"s Blue Waters - http://clapway.com/2015/07/26/the-reason-behind-lake-tahoes-blue-waters567/

The effects of Algae

Almost everywhere you go to a large body of water, there is some type of algae there. Sometimes, it is there in great accumulation, and other times not. But they’re good news for fishermen, as sometimes the fish like hiding in the shelter the algae, grass, and such provide.

But what do algae actually do to the water? Well normally when the algae blooms happen in the summer time, the atmosphere in the water changes, the pH level gets affects and the oxygen in the water end up dissolving.

This is especially troublesome if in stagnant water as there is no circulation of water to provide a new flow of oxygen for the fish and fishes end up dying out. But that’s not the only problem; algae also bring the levels of hydrogen up with the rise in pH level.

This is essential to the growth of algae in large amounts. The relationship between algae and water is quite paradoxical as it can raise oxygen but also deprive the oxygen in the water. Other concerns can be that some specimens release toxins which has been in the news recently in the Great Lakes area.

What does this have to do with Lake Tahoe’s blue waters?

Well, every so often the Tahoe Environmental Research Center check up on the status of the lake since its founding in 2004. This past Thursday on the 23rd, the TERC released their State of the Lake report.

The topic of choice for the report was Lake Tahoe’s blue waters. The reason why the lake is so blue is because of the low concentration of algae. That’s why in ponds, you see lots of green, as the algae concentration is likely higher.

Most assume that the water clarity attributes to the Lake Tahoe’s blue waters and blue water in general. However, the water could be blue and not as clear. The data that came from the report on Thursday suggests to the researchers and public that clarity is controlled by sediment disturbances and blueness to the algae concentration in the area.

What does this mean?

For one, we now understand the relationship better between water and algae and the effects each have on each other, the levels of influences in the environmental conditions. The other is that the Lake Tahoe’s blue waters have only been getting bluer in the past few years, indicating a lower algae concentration and clarity due to practically no sediment disturbances.

New Form of Algae Detection Emerges - http://clapway.com/2015/07/10/new-form-of-algae-detection-emerges654/

Determining blue-green algae hotspots could soon become a lot easier.

New research has emerged from the Laurentian University in Sudbury on determining new forms to test for algae in bodies of water. This new study has come from three years’ worth of research, and will involve direct scraping of algae itself instead of current methods of testing of the body of water that the algae is located in. One of the researchers, Charles Ramcharan, attests that this way of testing cuts result time in half, and can be done less frequently than current practices, which will allow for more time to analyze and work on possible solutions.

Ramcharan says, “It also means that we do a lot less work because we can go out and sample maybe once or twice a year. [We are] able to use the algae as sort of a long-term monitoring tool.”

Changing Algae Detection, Interaction, and Defense

Revolutionizing the way that algae is detected will vastly improve the ways that the scientific community is able to interact with the specimens. By being able to monitor the algae closer instead of simply relying on data determined from the algae’s body of water means that the data will be more accurate and precise in allowing for science to determine possible triggers and defenses against mass algae outbreaks.

This research also comes at a time when algae levels are predicted to rise dramatically. The National Oceanic and Atmospheric Administration (NOAA) predicts “the 2015 western Lake Erie harmful algal bloom season will be among the most severe in recent years and could become the second most severe behind the record-setting 2011 bloom.” If Ramcharan’s research is accepted, the new method of algae detection would mark a new defense against this natural phenomenon.

So, What Are Harmful Algae Blooms?

Blue-green algae is a form of harmful algae blooms, or HAB in the scientific community. Toxic algae can be harmful to humans, by causing several lesser-known illnesses such as Paralytic Shellfish Poisoning, which is usually diagnosed in Canada. It is not known what causes these toxic algae blooms. However, these new forms of testing, as well as our knowledge of possible environmental triggers, will allow for us to be that much closer in solving this mystery.

U.S.:Algae Blooms Cause Water Quality Problems - http://clapway.com/2015/05/26/u-s-algae-blooms-cause-water-quality-problems-123/

Algae blooms in the Great Lakes cause water quality problems every year and now more than $500,000 in state monies has been allocated to use to monitor and test the waters in the lake. In addition, the US Geological Survey (USGS) is setting up thirteen stream gauges in various parts of Lake Erie to aid in the monitoring system.

Algae Blooms Toxic to Human and Animals

Algae blooms have caused serious water quality problems in the past. For example, in August 2014, a half-million water customers in Toledo, Ohio, and part of Michigan couldn’t use their water for three days when a toxic algae bloom was seen to travel into the area. It was discovered that microcystin, created by cyanobacteria, had poisoned the water system at levels considered dangerous to humans by the World Health Organization.

USGS to Run Initiative to Monitor Water System for Water Quality Problems

The US Geological Survey will be in charge of monitoring the Great Lakes area waters for water quality problems, as they have access to special software called the National Water Information System (NWIS), which aids in acquiring, processing, and storing information about the nation’s water supplies.

While the USGS is now in charge of this venture, the US Army Corps of Engineers will end its jobs as the agency that warns people about blue-green algae water quality problems. Instead of travel into affected areas to sample the suspected toxic algae bloom or posting warning signs, they plan to put up permanent signs that describe how to interpret a possible algae bloom and determine its toxicity. It was thought that the temporary signs used previously caused the public to think algae blooms only happened at specific times, when they can actually show up at any time or place. However, they will still travel to lakes and other waterways that are managed by the US Forest Service and those that belong to some other agencies.

Money Will Help Form Strategy to Address Algae Blooms

The monies that have been allocated for the Great Lakes region will help with monitoring water quality problems, as well as to develop a strategy to handle algae bloom problems when they occur. It is hoped that by collecting data and monitoring, that the area can be kept clean of toxic algae blooms. The funding for the program to help with the water quality problems caused by the deadly algae blooms was especially marked for use by the USGS.
