Understandingthe Lake Data
It’sessential for the environmentalists, natural resource managers, andthe water users to evaluate and understand the physical and chemicalcharacteristics of the lakes. These features are subject to constantchanges. Other characteristics that are paramount while conductinglake water studies include the concentration of the dissolved gassesand the nature of the carbonate systems (Shaw,Mechenich, & Klessig, 1993).The two factors change seasonally due to the effects of the seasonalgrowth of plant and algae in the lakes. The annual variations areattributable to the groundwater inflow, surface runoff, sunlight, andprecipitation. The physical and chemical characteristics of a lake’swater are also influenced by the types of the lakes which isdetermined by either the source or the outflow of the water (Shawetal.,1993).Therefore, water quality determination and choice for the managementpractices of the water quality is significantly influenced by thetype of the lake. In most cases, a lake which acquires water fromprecipitation is likely to have low nutrient supply and highsusceptibility to acid rain. On the other hand, the local septicsystems may be the primary causes problems for groundwater drainagelakes. These lakes have a moderate amount of nutrients which areacquired from the soil and stored in the lake reservoir. This paperseeks to discuss the importance of long-term analysis of specificelements which determines the quality of lake water.
Byron,Christine, and Lowel (2016) describe the importance of variousmaterials regarding lake water quality. These substances includePhosphorous, Nitrogen, Oxygen, Sodium, Potassium, Carbon Dioxide,Magnesium, Calcium, Chloride, and Sulfate (Shawetal.,1993).Phosphorous is paramount in water quality regulation because it isresponsible for the growth of algae and other plants in the waterbodies. Although the increased population of the microorganisms maysupport a high variety of fish, it leads to adverse impactsassociated with oxygen depletion. This condition is dominant ineutrophic lakes which have a large accumulation organic matter.Moreover, Nitrogen has the same effect of increased plant growth inthe water bodies. The concentration of nitrogen in the rainfall isjust 0.5 mg/l. An environmental scientist may use this knowledge toregulate the amount of nitrogen deposited in the lakes in the form ofnitrites or nitrates. This material comes from organic matter whichis dissolved in infiltrating or runoff waters. The paths in whichthese elements get into the lakes could also help in the regulationof their concentration in the water. The suspended and dissolvedelements such as silt, organic matter, and animal wastes have asignificant influence on light penetration in the water.Consequently, water clarity impacts on the population of algae andthe subsequent effects on oxygen concentration (Shawetal.,1993).The chloride element is measured to determine the extents of waterpollution. A higher level indicates a rise in the concentration ofpollutants in water. The sulfate arises from the burning of coal.This component could also originate from the rocks in areas whereacidic rain is experienced. On the other hand, sodium, potassium, andcarbon dioxide indicate presence of pollutants resulting from thehuman activities on the watersheds. While carbonates and bicarbonatesare responsible for the water hardness and alkalinity, aluminum isblamed for increased acidity of the lakes. High acidity isresponsible for high mercury concentration in the fish (Shawetal.,1993).
Additionally,an understanding of these elements which impacts on the quality ofthe water helps in devising methods for water quality improvement.Such methods would include management of the sources of thesematerials. For instance, Phosphorous originates from farmland runoff,animal and human wastes, septic systems, detergents, and soilerosion. A natural resource manager who has an ability to identifythe sources of pollution in the lakes can effectively manage thequality of the water (Shawetal.,1993).
Along-term collection of the data regarding the characteristics of thelakes is essential in the monitoring of the water quality. Factorssuch as the oxygen concentration, algal populations, and speciesdiversity in the lakes can only be tracked over a long period. Theseconditions and their impacts on the lakes can only be evaluated by ananalysis of data collected from several years. Additionally, theefficiency of the management practices intended to improve waterquality can only be measured after a period of several years. Forexample, administration of the watershed to control increased supplyof the nutrients may not be instantly achieved (Shawetal.,1993).The nutrients may circulate within different zones of the lake formany years even after the watershed has been efficiently managed.Therefore, since it’s clear that the effects of the managementapproaches might not be apparent for a long time, data collectionshould be a continued process.
Inconclusion, as evident in this paper, the variations of oxygen,nitrogen, phosphorous, potassium, sodium, carbon dioxide, andcarbonates are very crucial in the analysis of a lake’s waterquality. Their concentration influences the population of fish andother organisms in the water bodies. For example, increasedconcentration of the nitrogen and phosphorous improves the growth ofaquatic plants. In turn, these plants increase the population of fishand put the marine lives at risk due to the possibility for oxygendepletion. A long-term record of the data concerning these elementsis significant because they vary in seasons and years. The effects ofwater quality management approaches can only be realized in the longrun and hence the need to track these factors for an extended period.
