GILLETTE - Gillette plans to rebuild a wetlands at Dalbey Memorial Park's Fishing Lake and may dredge the lake because of a nutrient buildup that's harmful to fish.

Levi Jensen, a civil engineer for Gillette, says nutrients aren't being removed from the water because of cattails and sediment. The nutrients help wetlands plants grow but are harmful to fish and other aquatic life.

Jensen says the city plans to reconstruct the area so it can efficiently remove sediment before it flows into the lake. The lake has been dredged twice since 1973.

The lake also collects oil, fertilizer, sediment and other pollutants washed into street drains and Donkey Creek from the south half of Gillette.

Jensen is conducting tests to see what pollutants are n the water.
