Health Alert issued for Iron Horse Trail Lake and Maskenthine Reservoir
The state has issued a health alert for Harmful Algal Blooms (HAB), also known as toxic blue-green algae, at Iron Horse Trail Lake in Pawnee County and Maskenthine Reservoir in Stanton County.
Samples taken earlier this week at the lakes on alert measure above the threshold of 8 parts per billion (ppb) of total microcystin, which is a toxin released by certain strains of blue-green algae.
When a health alert is issued, signs are posted to advise the public to use caution, and designated swimming beaches are closed during the alert. Recreational boating and fishing are permitted, but the public is advised to use caution and avoid exposure to the water, particularly avoiding any activity that could lead to swallowing the water. Do not let pets get in the water or drink from the lake. People can still use the public areas for camping, picnics and other outdoor activities.
Weekly sampling has been conducted at 55 public lake sites since the first week of May. The lakes will continue to be monitored weekly through the end of September. To view the weekly data for the lakes sampled, go to https://deq-iis.ne.gov/zs/bw/.
The state’s monitoring is conducted early in the week at public lakes with swimming beaches and high public activity. Sampling results for HAB and bacteria are updated every Friday and posted on NDEE’s website, Home. Harmful Algal Blooms may potentially develop in the time between sample collection and sample reporting, so the public should use caution if they see signs of algal blooms. HAB may also be present in other lakes in Nebraska that are not sampled. For more information about what to look for, potential health effects from HAB, and steps to avoid exposure, please refer to the HAB Fact Sheet on NDEE’s website /precautions-and-facts-regarding-harmful-algal-blooms-toxic-algae-nebraska-lakes-and-beaches.
