BMP grassed waterway

 (Above) A grassed waterway is a natural or constructed channel established in suitable vegetation for safe water disposal.

Primary Use: Erosion Control. Secondary Benefits: Safe disposal of runoff water; Improved water quality; Improved wildlife habitat.

 BMP Critical Area Planting

(Above) Critical Area Planting is planting vegetation on critically eroding areas.

Primary Use: Erosion Control. Secondary Benefits: Enhance attractiveness of site.

NRCS Handbook of Conservation Practices fact sheet.

Very similar to grassed waterway, but not engineered with sloping sides to direct water to center of channel (as grassed waterway is).


 Schuller AgWaste Pit2

 

(Above) Liquid Manure Storage Pit is a containment facility to store or process manure, manure-contaiminated runoff, precipitation or other process wastewaters that are in liquid form and can not be stacked as a solid. Common types include earthen-lined basins, geosynthetic-line basins, slurry-stores and (pictured above) concrete pits.

BMP Terrace w tile intake1    

(Above) Terraces are bench-like channels enabling water to be stored temporarily on slopes to allow sediment deposition and water infiltration. Tile Inlet is located in area of red circle.  No vegative growth, but you can see the embankment to stop runoff, allowing sediment deposition, water infilteration and the tile inlet.

Primary Use: Reduce Erosion.  Secondary Benefits:  Enhance infiltration and to control runoff.

NRCS Field Office Technical Guide fact sheet.

 

No vegative growth, but you can see the water will pool and drain through the tile inlet.


 BMP sed control basin growth circle

                                                                     Early season growth in the field, but the embankment is well vegetated already.

 BMP sed control basin growth2 circle

Plant Residue in the fields helps with runoff. The plant material on the embankment is already growing.

 

(Above) Sediment Control Basins are temporary basisn with a controlled storm water release structure, formed by constructing an embankment of compacted soil across a drainage way. Tile inlet is located in the area of the red circle.
Primary Use: Removal of sediment from runoff.  Secondary Benefits: Control of flow from a disturbed site.

 BMP Streambank before 

(1) Looking downstream along the Cottonwood River. Note unstable banks, little to no slope and many obstructions that can increase erosion along stream banks.

BMP StreambankAfter 

(2) "after" picture companion to image #1. Note many trees by the stream bank were removed and stream bank was reshaged to a gentle slope leading to river.

BMP Streambank before2 

(3) Looking upstream along a tributary to the Cottonwood River. Note unstable banks, little to no slope and farming activites right up to the edge of the stream bank.

BMP Streambank After2 

(4) "After" picture companion to image #3. Note that crops are no longer planted right up to the edge of the stream. Also note the stream barbs, the rock  "fingers" extending into the stream.

(Above) Stream Bank Stabilization or using Rock Rip-Rap on a stream bank is placing graded rock on a shaped stream bank surface to provide structural slope protection so erosion can be slowed or stopped.
Primary Use: Minimize stream bank erosion.  Secondary Benefits:  Improved habitat for aquatic plants and animals.

USDA Stream Corridor Restoration Handbook; NRCS Engineering Field Handbook fact sheet

 BMP stream barb1

(Above) Stream Barbs are low rock sills which project out from a stream bank and across the stream's thalweg (main flow within the river) to redirect stream flow away from an eroding bank. Stream Barbs are the rock groups sticking out into the river, rock rip rap is placed along the stream bank to help reduce erosion.

Primary Use: Minimize stream bank erosion.   Secondary Benefits: Improved habitat for aquatic plants and animals.

BMP gabion b4 

Before picture in Marshall, MN along the Redwood River, looking upstream from the bridge.

BMP gabion after 

After picture in Marshall, MN along the Redwood River, looking downstream towards the bridge.

(Above) Gabon Revetment or just plan "rock gabions" are metal baskets filled with rocks and secured along the bank of a river.

Primary Use: Erosion Control.    Secondary Benefits: Reduce sediment in the river.
