Silt Buildup Surveys at Weatherby Lake

Affinis Survey Team at Weatherby Lake

A lake may seem resistant to change, but hard rain events and construction activities taking place upstream can adversely affect its shorelines, capacity, and eco-system more than you may expect. Silt and mud will always accumulate at the points where tributaries feed water into the lake. However, seasons with extreme amounts of rain or construction performed upstream without proper erosion control can cause sediments to wash into the lake at alarmingly fast rates.
