Roughly 44.4 million tons of sediment produced by river erosion arrives at Glen Canyon Dam each year (Andrews, 1990; Weisheit, 2003). Thus, if all the sediment from the Gold King Mine spill were to reach Glen Canyon Dam, it would be diluted more than 600 times in one day by the 121 thousand tons of erosion sediment that enter the lake each day.

Over time, ponds will accumulate silt, fish waste and other impurities at the bottom. If they are allowed to get out of hand, these problems can cause a bad smell from the water, bacterial growth and even death of fish. A cleaning method called dredging is necessary to alleviate these problems.

Usually for every two acres of lake that you dredge, an average of three-foot of sediment, you will need an acre of upland area to place the material. This will yield an average elevation increase of six feet on land prior to consolidation. The closer this area to the lake, the cheaper the dredging costs will be with all other things being equal.

My main concern with building a 5' deep pond would be silt turning it into a 2' deep pond after a few years. My childhood pond went from 8-10' max to 5-6' max when some people built a house at the headwaters of the feeder creek which exposed a lot of silt for runoff. Real shame.

Muck Miners uses a hydraulic dredge to remove accumulated sediment with minimal disruption to the existing landscape. The sediment is transported through a pipeline to dewatering bags on the shore. The bags allow the water to escape while capturing the sediment. The water is returned to the pond and the sediment is dried.

Because ponds are often fed by other sources of moving water such as rivers and streams, they can form the end collection point for sediment, silt and other environmentally harmful materials. Over time, sedimentation — or the accumulation of unwanted debris — can pose a threat to both the aquatic life and plant life in and around a pond.
