Background
United Consulting
performs sediment surveys on lakes and ponds in order to
determine depths and volumes of soft sediments. Our
survey techniques allow us to quantify total sediments
as well as new sediment deposition.
Applicability
If you will be
starting a project with a lake or pond nearby, you
should consider conducting a Lake Sedimentation Survey
for your protection; disagreements leading to lawsuits
are becoming more frequent. Lake sediment surveys
provide valuable data concerning sediment loading and
deposition within impoundments. This data is typically
used to evaluate impacts on aquatic systems from
upstream development activities. The survey results can
provide baseline data prior to land disturbance
activities, which can be used for comparison with later
survey results, or can also provide data concerning
potential impacts that may have occurred during
construction activities and can be important in
assessing the overall health of an aquatic
system.
Procedures
United Consulting
can perform sediment surveys utilizing either a
conventional depth probe or ground penetrating radar.
Transects are established across the lake and the
sediment depths are measured across each transect. The
transect data is then used to develop cross-sectional
profiles of the lake bottom, showing the water depth,
depth of soft sediment, and the depth to the hard
bottom. The sediment depth data and profiles can then be
used to calculate sediment volumes. In addition, by
collecting core samples of the soft sediment, we can
typically determine the volume of any recent sediment
that has been deposited in the lake. United Consulting
has applied this technique on small ponds and larger
lakes, for developers, homeowners associations, and
individual property owners.
