Water Testing 110 Samples Collected Go Back 2023 Results 2024 Results 2025 Results Prevention is far better than remediation. The NLPA consulted with experts within TDEC and UT to determine what four critical pollutant indicators that we should include in water quality testing. Ammonia : Elevated levels via direct means, such as municipal discharges, animal/human waste, and agricultural runoff. Normal range is 0.01-0.50 mg/L. Cause for immediate concern is 2.5 Nitrate : Major sources of nitrate contamination can be from fertilizers, animal waste, and human sewage. A nitrate-nitrogen normal range is 0.2-3.0 mg/L. Conductivity : A measure of the ionic content (such as chloride, nitrate, sulfate, sodium, magnesium, calcium, or iron) in a body of water by measuring the water’s ability to conduct electricity; a large variance to a site's typical reading may mean that a pollution event has occurred. Freshwater lakes typically have a range of 100 - 2,000. pH : Optimal pH level for fish ranges from 6.5 to 9.0. At levels outside this range, fish become susceptible to poisoning from toxic chemicals. Changes in pH can also cause an overload of available plant nutrients, resulting in excessive plant growth and depleted oxygen levels for fish. IMG_2856 Testing Training IMG_4178 IMG_2856 1/5

This page provides educational information for all interested in what they can do to keep Norris Lake healthy from contamination for current and future generations by following tips for boat cleaning. Boat Care Invasive Species Control Go Back Watercraft Recommendations Download Clean, drain, and treat your boat if you take it from one body of water to another Boats are the most common way for invasive species to contaminate lakes. Of course, the best precaution is not to take your boat to another waterbody. But if you must, here’s how to clean your boats before you bring them back to our lakes – according to the regulations. NYS mandates reasonable precautions to prevent the spread of invasive species by boat traffic. Reasonable precautions are to clean, drain, and treat before launching your boat into a body of water – or relaunching it back home. Cleaning means that any visible plant or animal materials have been removed from the boat and disposed away from the waterbody. Draining removes water from the watercraft and the watercraft’s motor, bilge, and all other areas of the watercraft. Drain offsite and so that drained water, potentially carrying invasives, does not run into any waterbody. Treat the watercraft. Treat by at least one of three methods: air drying, rinsing or, as a last resort, towel drying. Air Dry either in dry, warm conditions or subfreezing temperatures. Air dry watercraft and trailers, uncovered, out of the water, and exposed to the sun or in a heated building for at least five days. Alternatively, store watercraft and trailers in continuous subfreezing temperatures for at least three days. Rinse Follow the steps as appropriate to the watercraft. In all cases make sure the water used does not drain into a waterbody. Rinse hull and other external areas or equipment with high pressure (2,500 psi) hot water (140 degrees F) for 30 seconds. Flush water cooled motors with water for two minutes. Flush the bilge area, live wells, bait wells and other water-holding compartments with hot water at a temperature of 140 degrees F for 30 seconds. If hot water is not available, thoroughly rinse the boat hull and flush water holding compartments with the warmest water available. Clean cold water is acceptable only if it is the only water available. Towel Dry Use in cases where the watercraft cannot be air dried or rinsed. Towel dry all portions of the watercraft hull, engine, trailer and associated equipment that have been in contact with one waterbody prior to launching in another waterbody. Notice that just taking the visible plants, animals, and mud off the boats is never enough. NYS DEC guidance on cleaning boats

The NLPA worked with the East Tennessee Environmental Educators (ETEE) to install two signs near the Sunset Bay Marina. The signs have information about invasive species and how you can help stop the spread of invasive species in lakes. Invasives and Watercraft Story Go Back Nov 20, 2023 The NLPA worked with the East Tennessee Environmental Educators (ETEE) The NLPA worked with the East Tennessee Environmental Educators (ETEE) to install two signs near the Sunset Bay Marina. One sign is located at the entrance to the boat ramp and the other near the entrance onto the Sunset Bay Marina. The signs have information about invasive species and how you can help stop the spread of invasive species in lakes. Inspecting and properly cleaning your watercraft before and after you put it in the lake is vital to keeping the lake free of invasive species. It is important that you also make sure our guests who bring their watercraft to the lake also understand these guidelines. It takes all of us to do our part to help keep the lake clean and allow everyone to enjoy it for years to come. The signs were designed and installed by the East Tennessee Environmental Educators (ETEE) and the Norris Lake Protection Alliance (NLPA). They were paid for through a grant obtained by the ETEE from the East Tennessee Development District.

Tips to keep your dock from pests, including manual removal, the use of essential oils to repel insects, and the contact information for a local professional. Dock Care Pest Management Go Back Download Safely Deal with Spiders et al Mechanically remove spiders and mud-dauber wasps with a long-handled brush. Make sure that you remove the egg sacks and nests regularly. They will continue to hatch out from past unremoved egg sacks however continued vigilance will demonstrate fewer spiders and webs over time. Use essential oils to deter pests from getting established on your dock. These oils have a strong scent that interferes with how insects navigate and communicate with each other. It repels spiders, wasps, hornets, boxelders, Asian Beetles, and several other nuisance insects. Fill a spray bottle with water and 15 drops of essential oil (peppermint, cedarwood, tea tree, vetiver, orange, cinnamon). Spray your dock, especially where spiders might build a web. If these methods aren’t producing the desired results, you may choose to call a professional. Norris Lake Pressure Washing (865)-498-9121 Invasive Pests in Tennessee
