Pond Restoration Program                            Lake Restoration Program

Of course, any of our services can be selected alone for individual needs, but our Pond Restoration Program has fully engaged all of our services.  This 3 year program will include everything that you need to get your lake or pond headed in the right direction.

Lakes and ponds are valuable and dynamic resources that can often times be difficult to manage.  Lake quality can be impacted by a variety of factors including, but not limited to: invasive plants and animals, fish populations, watershed, lake morphology and nutrient levels.  We design this program which can help to better understand all factors impacting your lake.  Over the 3 years of this program, we will look at the following:

  • Nuisance vegetation management - Licensed aquatic applicators will control nuisance vegetation every other week throughout the growing season
  • Bathymetric and plant biovolume map (Year 1 & Year 3) - Aquatic vegetation and depth data will be collected using hydroacoustic equipment.  This information will be used to create a high quality layered bathymetric and plant biovolume map.
  • Water quality testing - Samples will be collected in spring and late summer and analyzed for: dissolved oxygen/temp profile, Secchi, pH, Alkalinity, hardness, nitrate, total phosphorus, and ortho-phosphorus.
  • Electrofishing survey (Year 1 & Year 3) - Specialized boat mounted electrofishing equipment will be used to survey your lake in order to assess the fish community.  Data collected will be used to create recommendations for preserving and enhancing your sport fish community.
  • Application of nutrient reduction products - Water quality sampling will be used to select the proper products needed to lower nutrient levels and improve water clarity.
  • Installation and maintenance of a properly sized aeration system - Aquatic Control aeration specialists will analyze water quality and bethymetric data in order to design and install a properyly sized aeration system that enhances water quality and improves fish habitat by properly circulating your pond.
  • Annual diagnostic report - Electronic and hard copy reports will be generated at the end of each season that outline the year's activities and future recommendations.

Aquatic Vegetation Management

Before & After

Aquatic Control was one of the first professionally staffed companies to provide control of nuisance aquatic vegetation, using chemicals specifically registered for use in lakes and ponds. Our personnel were involved in the early field testing and evaluation of aquatic chemicals that are now EPA registered and in common use. We continue to work closely with chemical manufacturers, university personnel, and others involved in the production, testing, and regulation of aquatic chemicals. Our personnel are trained, tested, and licensed to handle the specific chemicals used in our business. The primary goal of Aquatic Control is to provide our clients with a program tailored to their specific desires and requirements. In order to assure our clients of the best programs available, we continue to test and evaluate new equipment and techniques every season. Through years of experience, we have developed specific maintenance programs which have proven to be effective by repeated experience under a variety of conditions.


One of the best known is our Clean Lake Maintenance Program for private and community lakes and ponds. These bodies of water are generally used for surface drainage control, recreation, and irrigation. Excessive nutrient input often causes nuisance algae and weed growth while the rapid flushing of storm drainage water lessens treatment effectiveness. Our Clean Lake Maintenance Program provides regularly scheduled inspections of the lakes
, with treatment as needed to maintain your lake's desirable condition. Clients contracted under this program may call for professional consultation on any lake problems which develop over the contract period. Many of our clients compare the Clean Lake Maintenance Program to having a professional experienced lake management biologist on their staff, at a fraction of the cost. Additionally, Aquatic Control offers per treatment contracts, custom designed treatment programs, and professional consultation for development of "in house" programs using EPA approved aquatic chemicals. A complete aquatic vegetation management program may include a variety of methods for controlling nuisance weeds. Aquatic Control is prepared to offer the following services: professional application of registered pesticides, nutrient precipitation, and water quality monitoring and analysis. We want to provide you with a vegetation management program to fit your specific needs.  Download Vegetation Managment Sheet PDF

Lake Mapping ServicesVegetation Biovolume Map

We have recently upgraded our equipment, completed specialized operational training, and teamed with a company called Contour Innovations to offer affordable, comprehensive lake mapping. Lake mapping is an important tool for lake managers. Gathering baseline data such as lake depth, plant coverage, and bottom hardness gives our biologists more information to better achieve aquatic management goals. In addition lake mapping helps us give our clients a more detailed and comprehensive view of a waterbody that allows one to objectively determine how a lake changes over time.

Predetermined survey tracks are downloaded to a boat mounted GPS/Sonar unit to insure that the area of interest is comprehensively surveyed. The operator of the boat then drives the boat along the survey tracks while the plant coverage, bottom hardness, location, and depth information is relayed from the transducer and GPS antenna to a digital storage device. The information is then uploaded and analyzed by Contour Innovations specialist who evaluates your data using custom acoustic algorithms, GIS tools and mathematics to create highly quality layered maps.  Sample Bathymetric Map

 

Fish Population ManagementFish Survey Graphic A

Fish populations often become unbalanced due to overharvest of predators, introduction of undesirable species, partial winter or summer kills, excessive weed infestation, etc. Our years of experience, study, and close relationship with other fisheries specialists has resulted in a variety of management techniques which can be implemented by lakeowners themselves. We provide many kinds of equipment for fish population management. We also provide experienced personnel to assist you or complete the projects on your lake.

 

Fish Survey

A common complaint of lakes and ponds is poor fishing. A biological system such as a lake or pond is a complex system with many interacting factors involved in the production of the desirable and balanced ecosystem. Fisheries scientists have developed and adopted various types of equipment for collection of unbiased random samples of fish. Aquatic Control biologists have modified standard sampling techniques used by governmental organizations to reduce the field and laboratory time, providing our clients a high quality, yet cost effective survey. Surveys will be modified to fit the individual requirements of your lake. The major sampling equipment utilized includes electro-fishing boats, water quality testing equipment, sonar equipment, and necessary laboratory equipment. We maintain a technical library for reference and continually integrate new methods of sampling and analysis of fish populations, providing you with "state of the art" service. A lake survey provides a starting point for lake improvement projects. Survey results often save our clients money by allowing cost effective, biologically sound management procedures to be implemented. Specifications for our fish surveys are available on request.  Download Fisheries Survey Sheet PDF

 

Aeration Equipment Installation & Maintenance

Fountain

Although the aeration equipment we sell requires a minimum of equipment or experience for installation and maintenance, we offer these services on request. Our experienced personnel can provide a fast, efficient installation, start up and water quality check at your lake. We can provide regular equipment maintenance and water analysis to insure maximum equipment life and continued effective operation.

Dissolved oxygen is the single most important water quality parameter in lakes and ponds. All fish life and natural fish food organisms depend on dissolved oxygen for life. Under natural conditions, oxygen is produced by plant life, primarily microscopic algae (phytoplankton) and surface diffusion from the air. This is distributed in the water by wind induced currents and by diffusion. These processes are adequate to satisfy the oxygen demand in lakes and ponds only under ideal conditions with very low input of fertilizers and organic materials (grass, leaves, etc.). Few lakes satisfy these conditions.

Most midwestern lakes and ponds thermally stratify during summer and winter months with intervening spring and fall circulation, commonly called lake turnover. During the stratified periods, oxygen demand is higher than oxygen production in deeper waters (8-10 ft. plus). This is caused by the aerobic (oxygen using) digestion or breakdown of organic matter. No oxygen is produced due to lack of sufficient light and distribution from shallow water is blocked by the thermal stratification. This situation quickly leads to an oxygen reduction or complete loss of oxygen in the deeper water. This results in several problem situations in the upper layer of water including: crowding, more competition for food, extreme fluctuations of pH, oxygen, carbon dioxide, temperature and other environmental factors. These place fish in a stress situation which results in less than optimum growth and performance. The deeper water becomes devoid of oxygen and decomposition of organic matter changes to anaerobic digestion with its production of methane, hydrogen sulfide, and partially digested organic matter. The cycle of accelerated eutrophication literally feeds on itself. This cycle is interrupted by use of proper aeration equipment. Aeration equipment provides oxygen to maintain aerobic decomposition and circulation patterns to distribute the life supporting oxygen throughout the body of water.

Aeration

Aeration equipment is available in a variety of types. Each kind has its particular advantages along with some disadvantages. In order to provide effective aeration equipment to satisfy a wide range of situations, we offer several types of equipment and strive to fit the equipment to the client's needs and wants. We are available to discuss your particular aeration needs. Let us assist you in selecting the equipment best suited for your situation.

Do-It-Yourself Lake Vegetation Control Program

The use of chemicals to control unwanted plant growth in ponds, lakes, and ditches has increased rapidly as more demands are made on these aquatic resources. This has also caused much confusion regarding what chemicals may be safely used in water. The proper choice of chemical for nuisance vegetation control is extremely important. There are basically two groups of aquatic vegetation: vascular plants and algae. Within these groups there are several general types.

VASCULAR PLANTS: plants having stems and leaves
1. Emergent - plants growing in or near the water with a large portion of the plant exposed above the water level such as cattails, rushes, spatterdock, and water willow.
2. Submersed - plants growing attached to the bottom soil and growing within the water column, often completely to the surface, such as elodea, curlyleaf pondweed, naiads, coontail, and milfoil.
3. Floating - plants which are either free floating, such as duckweed and watermeal, or plants which are rooted in the bottom and produce leaves which float on the surface, such as water lilies and watershield.
 
ALGAE: plants without true leaves and stems, many are microscopic
1. Chara and Nitella - specialized algae which grows attached to the bottom soil, extends into the water column and very closely resembles several vascular plants.
2. Filamentous Algae - probably the most common aquatic nuisance plant. Growth is highly variable ranging from very slick and slimy to coarse horsehair texture. Forms floating mats.
3. Planktonic Algae - single plants are mostly microscopic in size; however, due to high numbers present, they give the water a color (brown to green) and in very nutrient rich waters often “bloom” producing excessive growth and soupy green water. The blue-green algae group produces strong odors and some species also release toxins which have resulted in illness and death to livestock.
 
Within these general categories, there are many distinct kinds; or species of plants. Experience has shown that many factors affect the results of treatment programs including chemical choice, dosage rate, application method, timing, weather conditions, extent of coverage, water movement, etc. Some factors are beyond our control but must be considered in planning. The primary steps in planning an aquatic weed control program:
1. Use of water - check this against precaution statements for chemical.
2. Proper identification of nuisance vegetation. (Guessing can be costly.)
3. Proper dosage of chemical - varies with plant type and species. Rates are generally given by surface acre (43,560 sq. ft.) or acre foot (surface acres X average depth of water).
4. Time of application - most aquatic herbicides can be used effectively any time throughout the growing season with proper adjustments and precautions. Early season treatments when plants are actively growing are generally most effective and efficient.

We stock only registered aquatic products and the popular non-chemical vegetation control alternatives: Aquashade, Beachcomber Rake, Weed Razer, Weed Razer PRO and the Weed Raker. Application equipment is also stocked for your own lake management program. These items are presented in several categories with a brief explanation of uses and precautions for chemicals, to help you choose the correct equipment and materials.
