2007 Hemlock Farms Community Association Water Quality Results

The following chart details the water quality results documented from tests performed during each visit.  Temperature varies dependent upon time of year and seasonal temperatures.  An average D.O. (Dissolved Oxygen) level for a waterbody of your size is between 7 and 11 throughout the season.  An average pH would be 7 and Secchi visibility (Water Clarity and density of growth of Planktonic algae) is about 4 feet.  Alkalinity is the buffering capacity of the water.  High Alkalinity rates indicate that there are excessive nutrients present within the waterbody and a high mineral content.  High nutrient laden waterbodies will be vulnerable to persistent algae blooms.   Hardness is a measure of dissolved minerals within the water expressed as a measurement of calcium carbonate. Ideally, both readings should be below 50 mg/l.  Testing the hardness is helpful in determining application rates.  The higher the water hardness, the more herbicide and algaecide will be required to achieve eradication results.

Recommendations

Natureworks recommends the following for the 2008 treatment season...

 

ALGAE TREATMENTS

                 

Algae treatments are recommended to be continued.  Filamentous and Planktonic algae have been responding very well to the current algae management program. Management of nuisance algae production and control is recommended through a specifically tailored algae treatment program. 

Algae is caused and accelerated mainly by nutrient loading of waterbodies.  Nutrient loading can occur from outside sources such as run off from local farms, neighborhoods, nearby industrial sites, and/or fecal contamination by congregating waterfowl.  Excess nutrients may already be present within the waterbody itself and re-circulation of these nutrients can lead to severe algae blooms.  As waterbodies age, this natural process of nutrient cycling and loading has resulted in many waterbodies experiencing high algae production.  The algae blooms that occur require seasonal treatment maintenance to keep waterbodies free of growth and to maintain open-water areas. 

Not only is algae treated in waterbodies to enhance recreational use and aesthetics, but algae maintenance is important to fisheries.  As water temperatures cool in the Fall, algae decays reducing the amount of available dissolved oxygen within the water.  If this occurs too rapidly, a fish kill results.  Excessive algae growth also stunts growth of fish as crowding decreases the size of their environment.

Growth becomes especially prolific in lakes/ponds with shallow depths.  This is due to the decrease in water circulation resulting in stagnation, an overall increase in water temperature, and an increase in photosynthesis.

 When developing a comprehensive algae treatment program, a good rule of thumb is as follows: waterbodies that experience severe and frequent algae blooms require an aggressive treatment plan which includes 5 to 6 or more full applications to the waterbody.  Waterbodies that experience somewhat frequent blooms require 4 to 5 algae treatments dependent upon the severity of the blooms.  Waterbodies that experience less frequent blooms in which algae is easily treatable and blooms occur only monthly can opt for 3 to 4 partial algae treatments or 2 to 3 total algae treatments.  Waterbodies which experience only one or two blooms a season, generally when water temperatures increase from heat waves, can be treated on an as needed basis.  Your waterbodies experience blooms of both filamentous and planktonic algae for which we recommend regular monitoring and treatments as required. 

This treatment program will prevent Filamentous and Planktonic algae blooms and help to maintain an aesthetically pleasing, fishery friendly, environmentally sound aquatic environment.

 

WEED TREATMENTS      

 

When discussing maintenance of vascular plants, we place plants into 2 categories: Native- beneficial species and Exotic- nuisance species.  The plants that most commonly become problematic and require control measures are exotic species.  Exotic plants do not serve any benefit or function.  Exotic weed species are those not native to this country, brought to the United States as a result of the Aquarium Trade Industry.  Consequently, nature=s system of checks and balances is eschewed. The natural balance must be maintained by man since the exotic plants have no natural predator in this environment to control their growth.  As a result, their growth often expands exponentially and reaches nuisance levels in a short period of time..  Herbicide treatment is the most effective management option for eradication and to restore a native habitat and beneficial ecosystem.

Vascular plants growth is enhanced and accelerated mainly by nutrient loading of waterbodies.  Nutrient loading can occur from outside sources such as run off from local farms, neighborhoods, nearby industrial sites, and/or fecal contamination by congregating waterfowl.  Excess nutrients may already be present in the waterbody itself and re-circulation of these nutrients can lead to severe vascular plant growth.  As waterbodies age, this natural process of nutrient cycling and loading has resulted in many waterbodies experiencing excessive vascular plant growth.     

Not only are waterbodies treated to enhance recreational use and aesthetics, but maintenance is also important to fisheries. As temperatures cool in the Fall, weeds decay and consume the amount of available dissolved oxygen within the water.  If this occurs to rapidly, a fish kill results.  Excessive plant growth blocks the light to lower depths, crowds out the beneficial plants, and creates sediment build up, thereby, shallowing the waterbody, and stunts fisheries growth as crowding decreases the size of their environment.

Continued management of nuisance aquatic plant growth is recommended for treatment through a continued weed treatment program in the upcoming season.  This program will prevent vascular plant growth and help to maintain an aesthetically pleasing, fishery friendly, and environmentally sound aquatic environment.

 

 

MONITORING   

 

Monitoring is considered an integral part of the lake/pond management process.  By monitoring parameters such as water quality; vascular plant growth, spread and density; algal concentrations; fishery activity, health, and population distribution; changes in benthic topography; current and changing watershed dynamics; and general environmental changes, management programs and restoration measures may be appropriately initiated and implemented with the particular needs and changing needs of the waterbody in mind.  Monitoring aids in attaining baseline information.  From this information, comparisons and contrasts may be made on an annual basis that will detect trends/changes in the characteristic of the waterbody.  We recommend a monitoring program be continued in the upcoming season.

 

TREATMENT DATE/ MULTIPLE YEARS OF CONTROL

 

The treatment date is very important when utilizing herbicides due to plants= varying absorption rates.  Plants are most susceptible to treatment once they have entered an active growth state.  This most often occurs when the plants are at a height of at least 2 to 3 feet but prior to the plant producing seeds.  If timed properly, one single application can offer multiple years of control for certain species of plants.  However, usually several seasons of treatments are required before substantial control is achieved. 

Growth becomes especially prolific in waterbodies with shallow depths.  This is due to the decrease in water circulation resulting in stagnation, an overall increase in water temperature, and an increase in photosynthesis of nuisance benthic, vascular plants as sunlight easily filters to lower depths where plants begin to grow. 

 

LITTORAL ZONE/ AQUASCAPING            

 

Littoral Zone Planting/Aquascaping involves the planting and introduction of decorative and functional aquatic emergent plants to the shoreline of a lake/pond.  Some examples of these plants include: Water Iris, Pickerel Weed, Duck Potato, Arrowhead, Sedges, Rushes, etc.  Enhancement of the littoral zone will add not only to the aesthetic beauty of the lake/pond, but in the long-term, introduction of beneficial plant species can aid in nutrient absorption, promote sediment stabilization, offer a wildlife habitat, become a beneficial habitat for fisheries, ameliorate the severity of algae blooms, and control erosion.  Further littoral zone information is enclosed within this packet.  Should you be interested in Littoral Zone Planting/Aquascaping, Natureworks will prepare a planting proposal to include pricing upon request.

 

FOUNTAINS                       

 

Many of our clients have been requesting additional water features for their lake/ponds.  In response to the growing demand, we now carry several lines of fountains to better serve our clients= total lake/pond management needs.  Since your waterbody can be the focal point of your property, the addition of a decorative fountain would further enhance the aesthetic beauty of your aquascape.  Fountains can be a beautiful addition to any waterbody and require little maintenance.  Many fountains double as aerators which promote aerobic decomposition of organic materials, increase the dissolved oxygen at the benthic level, and aid in water circulation reducing stagnation.  In addition, water circulation speeds up the nutrient decomposition cycle in the water resulting in less available nutrients for algae blooms and vascular plant growth.  Fountains also provide oxygen to the lower depths of the waterbody which is beneficial to fisheries.  A sharp rise and fall in temperature as much as 12 degrees in a seven day period causes stress in the fisheries of the lake/pond.  The addition of a fountain will help circulate the water and establish a uniform temperature by eliminating temperature stratification throughout the water column.

When designing a fountain layout within any waterbody, a good rule of thumb to follow is to Aprovide 1.5 HP for every surface acre, 2 HP if the waterbody is particularly stagnant.@  It is important to take into consideration the shape of the waterbody so that placement of aerating fountains will provide the optimal water circulation where the greatest amount of water movement can be obtained.  The spray pattern which is most beneficial in improving water circulation is one in which the spray circulates a high volume of water over a broad area.  This spray pattern increases the time the fountain water is in contact with the air and promotes a greater exchange of oxygen prior to return to the waterbody.

A brochure has been included for your review.  Current pricing is also included.  The prices quoted include fountain system installation.  Several options are available including a wide variety of spray patterns and lighting options.  All fountains include a timer, ground fault circuit interrupter, and protective housing for the electrical components.  Please let us know if any of these systems are of interest.

 

AERATORS                        

 

Many lakes/pond containing depths of 5 feet or more can benefit from the installation of aeration units in strategic locations within the waterbody.  Aerators promote aerobic, microbial decomposition of organic materials and nutrients.  Organic matter decomposes rapidly when aerobic bacteria begins to attack.  This is a natural process.  Waterbodies by their very nature are anaerobic (lacking oxygen) at their benthic level.  Anaerobic decomposition is much slower than aerobic decomposition.  By adding oxygen (aerating) the water in a lake/pond and circulating this water, the benthic or bottom layers of the waterbody receive oxygen and support aerobic bacteria to break down the organic materials and available nutrients present.  Aerating the waterbody through the use of an aerating fountain or a submersed aeration system will improve the decomposition of this organic material.  The desired result is less available nutrients for algae blooms and vascular plant growth.  Aerators also provide oxygen to the lower depths of the waterbody which is beneficial to fisheries.  A sharp rise and fall in temperature as much as 12 degrees in a seven day period can occur and cause stress in the fisheries of the lake/pond.  The addition of an aerator will help circulate the water and establish a uniform temperature eliminating temperature stratification throughout the water column.

A brochure which illustrates the line of aerators we carry has been included for your review.  Current pricing is also included.  The prices quoted include aeration system installation.  Several options are available including a wide variety of spray patterns and lighting options.  Please let us know if any of these systems are of interest.

 

SWANS               

 

An over abundance of geese are present at the lake/pond.  While birds are fun to feed, the damage they do to a lake/pond is severe.  Geese are very dirty birds as they defecate next to, or within waterbodies.  This defecation acts as fertilizer for algae and weeds as it adds to the nutrient loading within the waterbody.  Not only have algae blooms in waterbodies been directly linked to overpopulation by geese, but fecal counts within these waterbodies are also found to reach dangerously unhealthy levels. 

Many techniques have been employed in an attempt to remove these waterfowl such as breaking of eggs, shooting of shotgun blanks, destruction of nests, and use of dogs to name a few.  However, more successful solutions have been the introduction of Trumpeter Swans or the use of a turf spread product called Rejex-it.  A brief explanation of each is as follows.

Swans are very territorial and chase other waterfowl from the surrounding habitat.  Geese are inherently afraid of swans and will look for another waterbody to inhabit.  Swans have a tendency to defecate further away from the waterbody rather than directly in or adjacent to it.  They also digest their food better than geese which results in less waste, and certainly 2 birds produce much less waste than 30 birds. In order for the introduction to be successful, a male/female pair must be purchased, a small shelter provided, and an open area of water must be maintained in the winter so that they will not look to reside elsewhere.  Maintenance of an open water area may be accomplished through the installation of a small, submersed aeration unit in a corner of the waterbody.   We can obtain swans from a breeder if you are interested in their introduction.  

 

REJEX-IT

The other alternative is a new systemic product available as a goose repellant called Rejex-it.  Although the solution is not harmful to wildlife, geese have been found to have an adversity to its grape taste and odor and in many cases, will find an alternate waterbody to occupy.  It is simply irritating to geese.   This liquid, non-toxic concentrate is diluted and sprayed directly onto the turf surrounding the waterbody where the geese congregate.  The application generally lasts through two cutting cycles of the turf.  Previously manufactured products were not absorbed into the turf but rather sat on the blades of the turf where it was eventually washed off or dissipated in the clippings.  Rejex-it has been improved and a surfactant has been added to give it sticking power and systemic action. Rejex-it is available in a variety of sizes to suit the customer’s individual needs. 

 

GATOR GUARD

 

The Gator Guard is an artificial Alligator head which is anchored to a line out in a pond and free floats around the pond attached to the line.  It has reflective eyes and the actual appearance of a real alligator.  We have found it to be the most effective tool for goose control to date.  The gator guard works best when the geese are not permanent residents of the pond. 

Gator Guards have been very effective on controlling geese at residential ponds as well as golf courses and community ponds.  Call for more information. 

 

FISH STOCKING               

 

An enclosure on Fish stocking is included within this packet.  It details the ideal balance between varying fish species and their management in a waterbody.  If this is an option you wish to pursue, Natureworks would be happy to tailor a stocking recommendation plan suited to your particular waterbody=s needs.               

 

FISHERIES INVENTORY 

 

A fisheries inventory is performed through electroshocking and requires specialized equipment.  An inventory can be performed to provide an accurate quantification of species present, estimate size of and growth patterns, and an assessment of overall general health.  Electroshocking is not harmful to fisheries as fish are only temporarily stunned.  An accurate assessment as well as stocking recommendations can be made from the survey.  Please contact us for a fisheries inventory cost proposal for your waterbody if this service is of interest.

 

GRASS CARP    

 

Sterilized Grass Carp are often effective in waterbodies that contain small amounts of nuisance weed growth and have no overflow.  In permitting for Grass Carp, up to 15 fish per acre are approved for areas of dense vascular plant growth.  Waterbodies that have an overflow are often required to meet specific dam requirements to ensure the Carp cannot escape.  Carp also produce a lot of waste and may contribute to algae blooms as they add to the nutrient loading of waterbodies.  Grass Carp tend to favor native beneficial plant species over nuisance exotic species.  Should both be present in a waterbody, the carp will often consume the native species first and then possibly move on to the exotic weed species.  Where overpopulation exists in native plant species, grass carp are a viable option.  Identification of weed species present is important prior to carp introduction to insure that the target plant is one in which the grass carp will forage.  Long term management plans are where the carp are best utilized especially when herbicide control is cost preventative.  Grass carp typically cost between $12.00 to $15.00 per fish, dependant upon quantity ordered.  Permitting is required prior to stocking.

 

LAKESIDE FERTILIZER                  

 

Natureworks recommends using a zero phosphorus fertilizer to fertilize adjacent lawn areas as phosphorus acts as a catalyst to algae blooms. Information regarding a lakeside fertilizer has been enclosed within this packet.

 

DRAWDOWNS 

 

Winter Drawdowns may significantly reduce the amount of weed growth that will occur the following Spring dependant upon the plant species present.  Certain weeds are not affected by freezing conditions making Drawdowns futile.  However, growth of plants that are susceptible to freeze can be delayed until later in the season or eradicated completely, again depending upon the species.  The plants present within your waterbody are affected by freezing temperatures and a drawdown is recommended..  Natureworks recommends a drawdown be conducted on an annual basis for a minimum of 30 days annually each Winter.  This will significantly reduce the amount of spring weed growth.  The level should be lowered by 4 to 6 feet for this 30 day period.  The exposed ground needs to experience a solid freeze throughout the 30 day drawdown period.  If an annual drawdown is not feasible, then a drawdown every other winter would be a possible alternative.

 

GRASS CLIPPINGS

 

On various occasions, the presence of grass clippings were noted within the lake/pond.  These clippings add nutrients to the water which acts as a fertilizer for algae and weed growth.  Many blooms can be directly related to this common occurrence.  Bagging grass clippings in areas surrounding the waterbody is strongly advised.

 

 

TRASH/ LEAF REMOVAL                              

 

Removal of leaves and trash in the areas where build up has occurred is recommended as these add to Benthic algae layers and can cause a foul odor during periods of decomposition.

 

REINFESTATION CONTROL MEASURES (rinse boats)                         

 

Natureworks recommends that installation of signs at all boat launch sites.  These signs would remind boaters to remove weeds from their boats and trailers both upon entering and leaving the waterbody to deter spread from waterbody to waterbody..  Visible warnings help to remind people of this responsibility.  Containers for their disposal are also recommended.
