DREDGING/ SEDIMENT REMOVAL

It is important that every waterbody contains depths of at least 4 feet. Ideal depths are closer to a 6 foot average. Waterbodies that have depths less than 4 feet experience excessive algae and plant growth due to increased water temperatures, water stagnation, and light penetration to benthic levels. Once weed growth becomes prolific in a shallow waterbody, sedimentation occurs each Fall as plants decay. Year after year, the waterbody becomes more and more shallow, until eventually the waterbody either fills in completely or becomes a wetland/bog.

For this reason, sediment removal/dredging is recommended when waterbodies become too shallow or overrun with sediment. Sediment should be removed uniformly throughout the waterbody. This sediment may be deposited to an on site location, to an adjacent site, or hauled to another location. Should hauling be required, costs can get very expensive. The less costly alternative is to remove the sediment to an alternate onsite location and place, grade, and seed the sediment. Once completed, the removed sediment becomes a natural landscape.

Sediment removals/dredgings are generally scheduled for the Fall when soils are not so saturated, the least rainfall occurs, and when the ground begins to harden. Sediment removal/dredging may also be performed during the winter months when hydrosoils are frozen enough so as to allow heavy equipment to be brought out into the middle of the lake/pond.
