2008 Toxic Blue-green Algae
and Bacteria Sampling Results
NDEQ conducts weekly or bi-weekly sampling for toxic blue-green algae and bacteria at a number of public recreational lakes across Nebraska from May through September, and these results are updated weekly. Samples are typically collected on Monday and posted on the web site on Thursday or Friday.
At the top of the table below is a list of
all
Current Lake(s) on Health Alert
for toxic blue-green algae. Lakes that have been placed on Health Alert must subsequently have two consecutive weeks of low readings before the alert is ended.
Click here for more information about Health Alerts and toxic algae.
The next category,
High E. Coli Bacteria Readings
, lists lakes that showed unusually high readings of bacteria in the most recent sampling, which can also be a health concern.
* Bacteria figures preceded by an asterisk indicate that the five-sample average is considered higher risk for illness through inadvertent ingestion during recreational activities.

The last category,
Other Lakes Sampled,
lists the results for lakes which are not under Health Alert for toxic algae, and their most recent sample results for bacteria are considered low.
