Lake Structure

E P I L I M N I O NThe topmost and warmestlayer of water is known as theEpilimnion layer. This layeralso contains the highestquantity of oxygen comparedto the other parts of the lake.This layer mixes thoroughlywithsurface winds andprovides fluctuations inoxygen levels. The warmtemperatures and higheroxygen makes this layersuitable for a majority of theflora and fauna species offish.

M E T A L I M I O NThe layer between theepilimnion andhypolimnion is called theMetalimion layer. Thislayer experiences a rapidreduction in temperaturewith depth (@ rate of 1degree per meter). Sincethe density of water alsochanges with temperature,the water does not easilyrise or sink in this layer.The metalimion layer isalso known as thethermcline layer.

H Y P O L I M N I O N The hypolimnion layer is the

lowest layer and is directlybeneath the metalimnion layer.This water in this layer is muchcolder and dense. The stagnantwaters of the hypolimnionlayer are too deep to besignificantly effected by surfacewinds and currents. Water thatis remote from surfaceinfluences has a relativelysmall temperature gradient. Ineutrophic lakes, this lowerlayer of water has no oxygenand is loaded with toxic anddecaying materials. The bottomof the lake is known as thebenthal.

E U T R O P H I C A T I O NPonds or Lakes that

support rapid algae orplant growth are termed“eutrophic” ponds.Eutrophication comesfrom the Greek work for“over fed” and that’s justwhat plants are when theytend to grow to fast. Suchponds are overly fertilewith plant food (mainlynitrates and phosphates).

Lake ManagementDredging and de-silting –

De-weeding/hyacinth control or removal (biological, chemical,

mechanical and manual measures, bio-composting

Bio-remediation (Clean up with bio-products - natural bacteria

breakdown, and aerators to churn the lakes)

Introduction of composite fish culture/larvivorous fish species to control

mosquitoes

Oxygen Deplation Out in the deeper, or limonitic part of the lake the plankton

take over. Plankton is a term used to describe thoseorganisms that float freely in the open waters of the lake.Included in this group are the zooplankton (animals) andphytoplankton (algae). Fish, of course, also roam aroundout here. In a more productive lake the area fish have toroam around gets smaller and smaller as summer

progresses. Oxygen in the deeper waters becomesscarcer as dead algae and other detritus rains down into thehypo limnion. Most fish won't be able to survive in dissolvedoxygen concentrations less than 5 mg/L.

Flash Objective To Oxygenate & Oxidize

To remove odor by way of de-odorizing products.

To control the growth of Algae & Fungus.

To remove bio fouling.

To clarify the water column & Pond bottom.

Protocol -1

QUICK FIX PROGRAMME:

To treat in combination with Triozon F, CLO2 & CuSO4.

6 Shock Doses & 32 Maintenance doses.

To use high power chemical dosing pump with elongated pipe for treatment @1 meter above Pond bottom level. Floating Service to be Supported by Dept.

Area of treatment to be spot decided subject to contaminant level.

Protocol-2 {Bottom Aeration} The installation of a pond bed

aeration oxygenates the water at the bottom, and eliminates the hypolimnion by low cost, low powered, continuous destratifcationof the thermal layers. The whole idea of aeration is to get oxygen into the deep water. Aeration with tiny air bubbles from bottom up and circulation of lower water layers helps to achieve uniform levels of oxygen and temperatures throughout the lake. Once the lake or pond is full of oxygen near the bottom, new insect larvae, snails and other fish food can begin to live at the bottom.

PROTOCOL-3 {BIO-ENZYME} A good lake is one, which

contains fresh; sparkling clear, sweet smelling water and which supports fish life free from excessive algae and weeds. Biotechnology based

solutions involve the use of scientific methods to aintain the

natural health of lake. The Essential components of a good Biological solution are:

(A) The presence of a sufficient quantity of beneficial facultative bacteria

(B) The provision for sufficient Pond/Lake Bed Aeration

Be-Aware Being Chemical dosing utmost care should be

taken while handling the products. Egg Has to be handled like egg. Glass has to be handled like glass.

Visible eruption of entrapped Algae will surface up, post treatment. Either this has to be remove manually, or flushed out thro outflow source.

Public & Press has to be kept informed that State is in process of cleansing the lake, hence for couple of weeks this situation is inevitable for good.
