Carter Lake has the following impairments:
For the past three years, the Nebraska Department of Environmental Quality (NEDEQ) has monitored the algae growth in Carter
Lake. Public warnings have been issued multiple times because of blue green algae blooms. In 2006, Carter
Lake was the first Nebraska lake to register high levels of toxic blue-green algae.
Turbidity: Caused by suspended solids and re-suspension
of sediment and nutrients due to shallowness, wind and waves, and speed boat traffic stirring up the bottom.
nutrients in the lake from lawn fertilizers and chemicals.
E coli: or
fecal coliform bacteria, which comes from mammal excrements.
PCBs are found in industrial and household wastes. The problem with PCBs (industrial waste) is that
they don’t go away and do not leave the lake. So any contaminants received from storm water from
industrial and urban runoff stays in the lake.
