Wetland Hydrology

The driving force for the development of wetlands is the hydrology. Important considerations in determining if a site has wetland hydrology is the time of year when a site has a high water table, the level of the groundwater, and the frequency and duration that the water table saturates the upper parts of the soil profile.

The wetland hydrology criterion is often the most elusive of the three parameters to observe in the field. Is your soil saturated for less than two consecutive weeks in the growing season during a year with normal precipitation?

Acorn's certified wetland scientists have been trained to use a variety of technologies to observe and monitor hydrology on a site.

When you have a site with unusual water conditions, such as flooding when the soil is frozen, a ditch, drain tile, lateral or equalizer pipes, or a field that is wet in the spring, and you don't believe that it is wetland, click here to contact us and we will talk with you about it. Start your own monitoring now.

Acorn can conduct a hydrology monitoring study that may be able to provide you with the hard hydrology monitoring data that you need to confirm to the wetland regulators like the U.S. Army Corps of Engineers permit administrator and the State Department of Natural Resources DNR that your land is no longer a wetland.

Just because it has hydric soils and hydrophytic vegetation (wetland plants) does not mean it is a wetland. It needs wetland hydrology also.

Changes in hydrology also change the wetland boundary. You may have a prior converted wetland or a farmed wetland. Don't loose the land you have worked hard to own by letting it be incorrectly labeled as wetland.
