SEDIMENT / NUTRIENT DETENTION BASINS
1. Impoundment basins are designed to remove sediment and nutrients from
concentrated sheet runoff from the watershed area flowing to the basin. This
removal process occurs through the storage of such runoff for a period of time
sufficient to allow natural settling of such particles prior to discharge of the
water which transports these materials. The life of the impounding structures
(dam and spillway(s)), should be indefinite with proper maintenance. The
expected life of the overall structure as an effective sediment and nutrient
removal system will vary, dependent on the management within the watershed
and other factors. While it is expected that such basins will perform for at
least ten years without sediment removal, it is inevitable that periodic
sediment removal will be required.
2. Periodically, and particularly following heavy rainfall, inspect the spillway(s)
for possible debris accumulation and erosion. Erosion of the grass-lined
emergency spillways should be repaired by filling eroded channels and
reseeding. Erosion immediately downstream of the spillway outlets also will
require close monitoring. Repair such erosion as soon as possible after
occurrence.
3. Maintain vigorous growth of desirable vegetation coverings (sod) in the
emergency spillways and on embankments. This includes reseeding,
fertilizing, and controlled herbicide applications as required. Periodic
mowing should also be done. Time mowing after nesting birds have hatched
(about August 15).
4. Maintain a grass filter strip around the perimeter of the basins.
5. Check for and repair damage to embankments by rodents or burrowing
animals.
6. Remove woody vegetation from embankments. Prevent trees and brush from
growing on embankments, abutments, or in the spillway areas. Control trees
and brush by hand cutting, mowing, or chemicals. Avoid grass damage by
herbicides and do not burn.
7. Monitor for possible settlement or cracks in the embankment section. Repair
as necessary.
8. Inspect the downstream toe of the embankment annually. If there are wet
areas or seeps at the downstream toe of the embankment, it could indicate a
serious problem. In the event such seepage is present, seek professional
assistance to evaluate the seep.
March 30, 2006 3
9. Fill all rills and gullies that occur on the embankments and vegetated spillway.
Reseed the filled areas.
10. Pipe inlet maintenance: periodically, and especially after periods of heavy
rainfall, inspect the principal spillway pipe inlet and the section of the dam on
the upstream end of the pipe. Remove all accumulated debris at the pipe inlet
and repair any erosion or soil loss on the dam at the upstream pipe entrance.
Upon lake drawdown for fish harvest or sediment removal maintenance,
inspect the drawdown pipe inlet end for debris or sediment accumulation.
Remove all such debris or sediment accumulation to assure this pipe will
function at the next lake drawdown.
11. Drawdown pipe valve maintenance: the purpose of this valve is to allow total
or partial reduction in lake water level for purposes such as shoreline
vegetation management, sediment removal, and fish harvest. Periodically (no
less often than once per year) operate this valve to assure the valve will open,
close and seat as designed. Repair or replace this valve as necessary.

GULLY STABILIZATION: GRADE STABILIZATION STRUCTURES
1. Grade stabilization structures are designed to reduce gully erosion by reducing
the overall gradient of the gully flow line to slow flow velocities to levels that
are not erosive to the native soil materials. The structures are designed of
materials that can be transported and placed within the active gullies with as
little disturbance to the surrounding forested areas as possible. No effort has
been made to regrade the eroded gully sections between structures. It is
intended that these portions of the gully will stabilize by the deposition of
transported soil material and through natural succession of plant life.
2. The estimated life of these structures is at least ten years. The service of these
structures can be extended and improved by the development and
implementation of an operation and maintenance program.
3. Periodically, and particularly following periods of heavy rainfall, inspect the
various structures for signs of damage and failure. Repair or replace damaged
structures or portions of structures as required.
4. Type 2 structures constructed of posts, welded wire fabric, and brush may
require replenishment of the brush material. It is to be expected that such
material may be displaced by heavy flow rates and will consolidate with time
due to decay and rotting of the native materials.
5. Remove any blockage or obstruction to the weir (spillway) sections of the
various structures.
6. Pay particular attention to the areas immediately downstream of the structures.
A certain amount of scouring due to water flow can be expected in the
immediate downstream areas, but erosion or scouring that may threaten the
integrity of the structures will require repair.
March 30, 2006 5
SHORELINE STABILIZATION
1. Shoreline stabilization utilizing off-shore breakwaters constructed of stone
riprap functions by dissipation of wave energy and the elimination of wave
contact with the erosive shoreline soils. No effort is made to regrade or shape
the eroded shoreline in the installation process. It is intended that the
previously-eroded areas will stabilize through natural processes, including
natural succession of plant life, after the construction of the breakwaters.
2. The estimated life of these structures is indefinite with proper monitoring and
maintenance.
3. Periodically inspect the installations, paying particular attention to areas of
possible damage by wave action or manipulation. Damage may be subtle, and
indicated only by a reduction in height of the structure by displacement of the
upper surface over time. Such possible reduction in structure height will,
however, lead to eventual failure of the section, and must be repaired by the
placement of additional stone.
4. Damage may also occur to such structures by deadfall (eroded trees). Such
deadfall should be removed, and the displaced stone replaced to original
configuration.
5. Damage can also occur due to vandalism or removal of stone for boat access
or hunting or fishing access. Such areas will also need to be replaced.

ABSTRACT FROM PRESENTATION BY JOHN SEVERSON
Wetland habitat enhancement and shoreline stabilization using rip rap breakwaters
on Kinkaid Lake in southern Illinois
John Severson1, Jack Nawrot2, Michael Eichholz3, and David Fligor4
ABSTRACT
Reservoir shorelines are often impacted by severe erosion due to excessive slopes,
saturated upland soils, and chronic wave action. Affected shorelines remain unvegetated,
resulting in bare substrate, receding banks, and decreased water quality. Conventional
bank rip rap effectively reduces erosion; however, habitat benefits are minimal. In
contrast, rip rap placed ~10 – 40 feet from the eroded bank as a breakwater can reduce or
eliminate wave energy, leading to habitat development through wetland and aquatic plant
colonization.
Kinkaid Lake, a 2,750-acre reservoir in Jackson County, Illinois, is approximately
13 miles long southeast to northwest and supports ~80 miles of shoreline. The main lake
body has a 3,280 – 5,740 feet fetch that can generate large waves. Wave action has
eroded >27 miles of shoreline (~34%), forming shallow underwater shelves and vertical
banks. Banks have receded up to ~3 feet/year due to wave erosion. Eroded banks have
deposited more than 527 acre-feet of sediment within the basin. From 1999 – 2003,
approximately 6,000 feet of rip rap breakwaters were installed on shelves of the severely
eroded shorelines to reduce wave erosion and sediment deposition within the lake and
promote bank stability and wetlands establishment.
Breakwaters were monitored from 2004-2006. Breakwaters reduced wave energy
within the protected areas leading to bank/littoral stabilization and natural vegetation
establishment. This contributed to water quality, aesthetics, and habitat. Increased
vegetative cover (6x) and richness (10x) were observed at protected sites (121 spp.)
compared to unprotected sites (12 spp.). Numerous wildlife species were observed in the
newly established habitat including mammals, birds, fish, reptiles, amphibians, and
various invertebrates.
