“…Water is a major issue for the survival of all living organisms and it is a vital resource for any environment for their development. In the recent time the variation in water quality is affected due to the increased anthropogenic activities, domestic wastewater discharge and aquaculture activities in and around the lake (Kumar et al 2016). The water quality assessment is based on the value of several physical, chemical, and biological indices (Bhutiani et al 2016).…”

Kolleru lake is one of Asia’s largest freshwater lakes, which has undergone tremendous changes in the water quality due to the sewage, pollution and development of aquaculture in its surrounding area. This study is undertaken to evaluate the present water quality scenario existing in Kolleru lake, which has been affected seriously due to the anthropogenic disturbances since long. Water samples were collected from ten sampling locations within the lake during pre and post-monsoon seasons of 2017-18. A total of 11 water quality parameters were analysed such as pH, temperature, EC, TDS, TSS, total alkalinity, total hardness, dissolved oxygen, salinity, COD, and nitrates. Parameters were estimated by using a standard protocol of APHA 2012. The spatial distribution maps of water quality were generated from pre and post monsoon data using Arc GIS software. Spatio-temporal variation of all parameters indicated that the water quality found was unsatisfactory within the Kolleru lake. The present study shows the better water quality in the post-monsoon season. The Inverse Distance Weighting (IDW) interpolation spatial mapping was also used for water quality mapping to observe the environmental variation for protecting the important freshwater ecosystem-Kolleru lake. The outcome of GIS analysis demonstrated the spatial visualization of the lodging evolution and geographical distribution trends of water quality parameters within the study area.

“…Human settlements covered a small area (0.65%) in 2017, which was 0.33% only in 1997. Human settlement near lake bed region had increased with rising aquaculture activities and main activity of people in lake area is fishing (Kumar et al, 2016). The statistics showed that aquaculture practices in the study area decreased from 56% to 24% during the year 1997 to 2017, respectively.…”

“…(Rao et al, 2000;Sellamuttu et al, 2012). Lake quality is deteriorating due to effluent inflow into the lake from surrounding industries (Amaraneni et al, 2004;Kumar et al, 2016). As the lake is shallow, nutrients reach higher levels in the lake and…”

Aim: The present study is an attempt to analyze the land use pattern of Kolleru Lake in and around by using the techniques of remote sensing and GIS to detect the temporal changes of the Kolleru Lake. Methodology: The 1938 and 1967 years topographic sheets and Landsat-5 TM of 1997 and Resoucesat-2 LISS 4 of 2017 satellite images were used and analyzed by the latest version of Arc GIS 10.4 and ERDAS IMAGINE 2016 (Version 16.00). Unsupervised and supervised classification was done for 1997 and 2017 images, respectively. Results: It was estimated from the topographic map of 1938 that the total lake boundary area was 230.15 km2. Digital image processing of 2017 satellite data revealed that the lake area of 76.9 km2 (32.45%) only remained degraded, extensively colonized by macrophytes. The land use/land cover maps of 1997 and 2017 revealed that lake area was significantly occupied by aquaculture which amounted to 84 km2 (36.53%) and 56 km2 (24.35%), respectively, and no aquaculture activity was reported from 1938 and 1967 toposheets. Interpretation: The geospatial analysis data gives accurate and reliable information and associated factors. The spatio-temporal analysis data provide a significant foundation for monitoring activities in other lake systems, and are applicable to monitoring wetland use patterns in other sites of international importance.

“…Lakes are landscape elements that are very vulnerable to environmental changes. The pace of such shifts varies depending on climate changes as well as anthropogenic activities (Bai et al, 2011;Naga Kumar et al, 2016;Zhang et al, 2019). Water bodies and lakes occupy a small part of the Earth's surface (∼3.7%), but are key features of the hydrological cycle (Verpoorter et al, 2014).…”

“…Lakes are in most cases, the changes consist in areas decreasing as a result of human activities, e.g. land development (Chen et al, 2018;Grzywna & Sender, 2017;Povilaitis & Querner, 2008), change in land use (Jakubínský & Báčová, 2013) and others (Hara et al, 2014;Naga Kumar et al, 2016;Meyer et al, 2017;Molewski & Juśkiewicz, 2018).…”
