A sampling program to examine the resuspension of sediment and nutrients from disturbances in the nearshore zone of Lake Coeur D’Alene.
Here we are quantifying the resuspension of sediment, nutrients, and metals into the water column from different substrate types (sizes) and in response to i) wind waves and human caused wakes on calm, and windy days, ii) different boat types (Pontoon, Ski/V-hull and wake boats) which iii) pass at various distances from shore. This is being combined with daily satellite counts of boats on the lake to derive a whole-lake boat use index.

The release of nutrients and sediment from wave- and wake-induced nearshore disturbances in Big Payette Lake, ID.
Here we examined and quantified the sediment (turbidity) and phosphorus (both total and dissolved) in the lake bottom that is susceptible to- and resuspended by waves (natural) and wakes (human caused) impinging on shorelines with different substrate types (e.g., silt, sand, cobble, rocks etc.) to assist the Big Payette Water Quality Council to identify strategies to protect the future water quality of Big Payette Lake so it can continue to serve as the water source for the City of McCall.

Willow Creek Reservoir Water Quality Research and Evaluation Studies: 2020-2025
We are evaluating the operation of a bottom aeration system to determine optimum operation conditions to maximize hypolimnetic aeration, prevent destratification of the water column, and minimize internal loading of phosphorus (P) to bottom waters and the reservoir in general. The overarching goal is to reduce the occurrence of harmful blooms of cyanobacteria. Part of the work is focused on development of a novel aerator shroud to allow for the 35’ annual draw down as irrigation water is withdrawn from the reservoir.
