State officials lifted the alert after Rockford Lake, located in Gage County, passed two straight weeks of tests.
No public lakes are under health alerts at this time.
The Nebraska Game and Parks Commission reports the Nebraska Department of Environmental Quality two weeks ago detected elevated toxin levels produced by blue-green algal blooms in the lake, triggering a health alert. Health alerts are not ended until a body of water passes two straight weeks of testing.
NDEQ tests all 51 public lakes each week during the boating season.
Sampling results for harmful algal blooms and bacteria will be updated every Friday and posted on NDEQ’s web site, deq.ne.gov.
