Long Lake Sediment Basin Dredging

Project Overview

The Rice Creek Watershed District in Ramsey County, Minnesota, adopted a water resource management plan to address excessive sediment loading and associated phosphorus loading from Rice Creek and its upper watershed.

After a site survey of Long Lake confirmed that sediment had exceeded capacity, the district hired Veit’s Marine team to dredge the basin to maintain its functionality as a recreational lake.

Veit dredged the sediment to improve water flow and water conditions within Long Lake and Rice Creek. This project included hydraulically dredging 18,000 CY of material from Long Lake, dewatering the material, and disposing of the excavated soil materials not acceptable for use as backfill or fill.

The Dredging and Dewatering team constructed a dewatering facility to dry out and separate the material from the water. Erosion-control blanketing and a floating silt curtain were used to control erosion on the banks. 

Veit Marine successfully created site access to Long Lake and protected the environment for the future.
