Small and temporary freshwater rock pools, compared to lakes, ponds and rivers, have received a very little scientific attention in India. For the present limnological study, six rock pools in the river Chenab at Dhoomi, Akhnoor, were analysed seven times for water quality and fauna during 17-01-2011 to 26-01-2011 and have been described. Among various water parameters depth (6-11 cm), transparency (6-11 cm) and turbidity (1.4-6.88 NTU) recorded a decrease after high record on first observation. Salinity remained constant (0.1 ppt) on all the seven observations. Dissolved oxygen (DO) observed maximum (12.81 mg/l) record on 19-01-2011 and minimum (9.99 mg/l) on 26-01-2011. Chloride (Cl?) was minimum (2.73 mg/l) on 17-01-2011 and 18-01-2011 and maximum (6.81 mg/l) on 24-01-2011. Conductivity (75.50 – 178.8 µS cm?¹), total dissolved solids (TDS)  (40.13 – 85.5 mg/l), Biological oxygen demand (BOD) (2.5 – 6.63 mg/l), pH (8.26 – 9.12), carbonate ( CO3-2) (2.31 – 22.84 mg/l), bicarbonate (HCO3-) (29.83 – 71.29 mg/l), calcium (Ca+2) (9.45 – 29.50 mg/l), magnesium (Mg+2) (2.24 – 5.38 mg/l), total hardness (TH)  (35.34 – 95.80 mg/l) and sodium (Na+) (0.44 – 1.05 mg/l) showed highest record on last observation. Potassium (K+) (0.60 – 1.70 mg/l) was minimum on 18-01-2011 and maximum on 24-01-2011. Nitrate (NO3?) (0.084-0.373 mg/l), phosphate (PO4³? ) (0.043 – 0.140 mg/l), silicate (SiO4-4) (1.28 – 3.95 mg/l) and sulphate (SO4-2) (4.89 – 7.84 mg/l) observed  an irregular pulse. Fauna in these rock pools was represented by zooplankton (passive dispersers) belonging to Protozoa (27 species), Rotifera (3 species), gemmules of Porifera (2 species) and Turbellaria (1 species) only. Zooplanktonic maximum qualitative record was observed on 6th observation and quantitative on 7th observation. In the absence of any earlier study on freshwater rock pools in the Himalayan rivers, present work shall be of great help for future workers.

Satluj River

Present investigation was carried out on Satluj river in Himachal Pradesh for the analysis of important physical and chemical water quality parameters during November, 2015 to February, 2016. Parameters such as turbidity, total alkalinity, pH, conductivity, magnesium hardness, biological oxygen demand (BOD), chemical oxygen demand (COD), dissolved carbon dioxide, total hardness, chloride, phosphate, nitrate and calciumwere analyzed from five sampling stations i.e. First Sampling Station (SS-1) – Khab, Kinnaur, Himachal Pradesh; Second Sampling Station (SS-2) – Wangtoo, Near dam site of Karcham Wangtoo Hydroelectric Plant, Kinnaur, Himachal Pradesh;Third Sampling Station (SS-3) – Bayal at the Rampur city, Shimla, Himachal Pradesh; Fourth Sampling Station (SS-4) - Kol dam, Bilaspur, Himachal Pradesh and Fifth Sampling Station (SS-5) - Wajipur Kalan, Ludhiana, Punjab in the study area. The analyses were carried out according to APHA, 2012 procedures. The analysis of data reveals that turbidity, chemical oxygen demand, biological oxygen demand and chlorides were found to be higher than the acceptable limit prescribed by Bureau of Indian standards (BIS), WHO standards. Higher values of these parameters reveal that the pollution in Satluj river is due to siltation, domestic & municipal sewage, industrial sewage and surface run-off that effect the water quality directly or indirectly.

Benthic Survey

In west central Philippines, the monitoring of aquatic systems traditionally focused on dissolved oxygen values and biological oxygen demand, e.g. monitoring by the Environmental Monitoring Bureau around Panay Island. However, single or two factors are considered to be insufficient to assess habitat health precisely. In this paper, we investigated a benthic community and xamined their implications to habitat health of the Iloilo River. According to a prior benthic survey, warning signs pertaining to biotic, abiotic and community factors have been detected. The disturbed onditions in Iloilo River can be attributed to 3 factors; 1) its inherent topography, where bends serve as sinks for materials; 2) the lack of vigorous water exchange that promotes deposition and hinders complete flushing; and 3) the manner of utilization of the river by the local people. We thus concluded that: 1) monitoring for water parameters only is not enough to get a clear picture of habitat health; and 2) proposed that biotic components should be included for monitoring aquatic system.

The hydro geochemical features of Neyyar River for a period of one year from May 2015 to April 2016 were analyzed. Six sampling sites were fixed considering physiography and present landuse pattern of the river basin. The residents in the drainage basin are primarily responsible for framing a better landuse and thereby maintain a good water and sediment regime. Geospatial pattern of the present landuse of the study area indicated that the sustainability of this river ecosystem is in danger due to unscientific landuse practices, which is reflected in the river quality as well. The parameters such as hydrogen ion concentration, electrical conductivity, chloride, Biological Oxygen Demand, total hardness and sulphate of river water and Organic Carbon of river bed sediments were analyzed in this study. The overall analysis shows that the highland areas are characterized by better quality of water together with low organic carbon, which is mainly due to better landuse and minimal reclamation. The midland and lowland areas are characterized by poor quality of water with high organic carbon, which is due to high anthropogenic activities and maximum pollutants associated with the region together with the alteration in landuse from a traditional eco-friendly pattern to a severely polluted current pattern.

A study was carried out for preparing baseline information on water quality, population status and threats to Mugger crocodile, Crocodylus palustris Lesson at Rani Tal, Shuklaphanta Wildlife Reserve. Water quality analysis was conducted for three seasons (summer, autumn and winter) in the year 2008 - 2009. The study has found the physico-chemical contamination in the lake. The water quality parameters (dissolved oxygen, total hardness, free carbon dioxide, biological oxygen demand and ammonia) exceeded the normal range to support the Muggers. A survey around the lake recorded four adult Mugger crocodiles (>180 cm body length) basking in sandy and muddy bank during the investigation period. The lake is under pressure from diverse anthropogenic factors. The principal threats to the Mugger crocodile include water pollution, habitat destruction, sedimentation, food shortage, egg collection and seasonal fluctuation of water level. The total area and depth of the lake is diminishing due to encroachment by Phragmites karka and flash flood during monsoon. Conservation and proper management of the lake are urgently required.
