Dams are engineered structures designed to impound water. Most ponds primarily have an earthen dam, but they can also be constructed of concrete. There are many key factors to investigate when assessing the condition of your dam. Earthen dam embankments should be vegetated with native grasses to provide adequate ground coverage and prevent erosion and rills from forming. It is important to routinely maintain any non-native species of vegetation on the backside of the dam. This includes the removal of any trees, as they have an extensive root system that can cause prolific damage if they were to topple over. An overgrowth of brush and woody vegetation can make it difficult to notice any seepage or erosion issues during an inspection as well. Nuisance animals like beavers and muskrats will burrow into earthen dams and compromise the integrity of the structure. Outfall plunge pool areas are located on the backside of the dam. These shall remain clear of vegetation and debris as to not impede the flow of water. Additionally, you will locate toe drain outlet pipes in this area as well. These are utilized to collect water seepage and direct it appropriately downstream.
Contact a Civil Engineer to have to have your dam inspected today. Routine maintenance and inspections will prevent costly repairs in the future.
