One of the major impairments in the Muskegon Lake Area of Concern is the loss of fish and wildlife habitat. A habitat restoration project was initiated in 2012, which would hydrologically reconnect a former wetland, which was drained for agricultural production and later refilled to form ponds, to its adjacent stream. Initial studies indicated that the ponds sediments contained significant amounts of legacy phosphorus (P), so reconnection risked the net movement of P from the restored wetland to downstream water bodies. Additional P in downstream waters was problematic, as a TMDL for P was already in place; therefore, pond sediments were dredged in 2016. To evaluate the success of the dredging at reducing P release from the reconnected wetland, we are now repeating experiments to measure P release rates from incubated sediments. These sediment cores will be incubated under two water temperatures (ambient; +2°C) and two oxygen levels (oxic; hypoxic), resulting in 4 different treatments. Additionally, P isotherm experiments will be done to provide more information on the effects of sediment dredging on P dynamics in this wetland. We will compare results from post-dredging with those from pre-dredging to evaluate the efficacy of sediment removal as a restoration approach. Understanding the success of the dredging at reducing the P release from this wetland will help determine if additional management techniques are needed to avoid further impairment of downstream water quality.
