Our crew at Gravel Grading & Excavating is dedicated to moving the earth for our clients and customers. We jump at the opportunity to assist with any project that we can, especially those that consist of waterway or sediment basin work because the efforts can benefit future generations of Iowans. Maintaining a sediment basin or waterway is essential to preserving Iowa’s most precious resource, black dirt topsoil.
To help aid water drainage for a local community in the summer of 2020, our Gravel Grading & Excavating crew was called in to help clean out an existing drainage basin that had reduced efficiency after years of silt/sediment collection. Years of rain events had moved so much dirt into this drainage area, that all you could see of the outlet's 10-foot structure was the cap (pictured below). This told us that it was more than time for the silt basin to be cleaned out.
Sediment basins are ponds with open water that capture coarse sediment and litter carried by stormwater or runoff. They intercept the runoff before it reaches the waterway, and slow it down to allow the coarse sediment to fall to the bottom.This way the cleaner water stays at the top of the pond and flows through the outlet source.
A well-designed sediment basin should be just large enough to allow time to capture most of the target coarse sediment. It should only capture a small amount of finer particles and contaminants, the majority of which should be treated by a constructed wetland or raingarden downstream.
In order to maintain a sediment basin, it needs to be cleaned out regularly, usually every two to five years.
For our project in question, almost 10 feet of outlet pipe had been covered up with sediment over the years. Using our dozer, excavator, and wagons, our crew was able to clean out all the dirt that had settled in, and used it to build up the sides of the existing berm structure. See the photos below to watch our crew unearth and relocate years of sediment.
Our guys then relocated the dirt and shaped the berm and drainage areas to facilitate future runoff and soil preservation efforts.

Farmers in this area can tell you, no matter the season, there's always work to be done. Though summer may be overlooked as a time to just sit back and watch the corn grow, this time of year our friends in the ag sector keep busy with spraying and side-dressing crops, cutting and baling hay, tending livestock, and prepping machinery for the impending harvest season. Summer is also a time where farmers survey their fields for ways to improve efficiency and production and to implement erosion control measures.
Reconstructing waterways is one way to satisfy these needs. By clearing (cutting down and removing) and grubbing out (removing roots and stumps left behind) freely-growing trees and shrubs along fence lines and waterways, farmers can gain acres for additional planting which increases their production. Or, as in the case of our clients pictured below, they needed additional erosion-control measures put in place to reduce field runoff after the heavy summer rains.
In these photos from a crop farm near Monticello, IA, you can see how trees and shrubs had grown up along the creek near this field. Not only did these growths get in the way of farm machinery, but the steep banks on the sides of the creek meant the landowner was losing precious dirt and topsoil when rainwater drained off the field.
To help aid water drainage, Gravel Grading & Excavating came in to alleviate the problem. Using dozers and excavators, we started with clearing and grubbing the existing creek banks. All trees and shrubs were removed and hauled away using our dump wagon. We then laid back the banks at a better grade to allow for maximum water retention and less loss of soil for our farmer. Our last step of this project was to lay down grass mat and seed to encourage quick regrowth of natural grasses and ground cover.
