“…Additionally, the findings of this study suggest that significant rainfall variations cause extreme seasonal surface runoff and rapid changes in the water quality (Chlorophyll- a , DO, NH 4 + , and NO 3 – ) of this subtropical lake, as well as rapid variations in the phytoplankton community ( Figures 3 , 2 , 5 , 7 ). Studies on the temporal variations in the phytoplankton community have been carried out in temperate regions, but only a few have been reported in tropical or subtropical regions, such as Lake Cajititlán ( Limón-Macias et al, 1983 ; Umaña-Villalobos, 2010 ; Riediger et al, 2015 ; Li et al, 2018 ; Ma et al, 2019 ; Quevedo-Castro et al, 2019 ). The wet season in tropical and subtropical areas exacerbates the cultural eutrophication of surface water bodies when there is intensive agricultural activity in their basin ( Barbosa, 2009 ; Cunha et al, 2013 ).…”

Lake Cajititlán is a small, shallow, subtropical lake located in an endorheic basin in western Mexico. It is characterized by a strong seasonality of climate with pronounced wet and dry seasons and has been classified as a hypereutrophic lake. This eutrophication was driven by improperly treated sewage discharges from four municipal wastewater treatment plants (WWTPs) and by excessive agricultural activities, including the overuse of fertilizers that reach the lake through surface runoff during the rainy season. This nutrient rich runoff has caused algal blooms, which have led to anoxic or hypoxic conditions, resulting in large-scale fish deaths that have occurred during or immediately after the rainy season. This study investigated the changes in the phytoplankton community in Lake Cajititlán during the rainy season and the association between these changes and the physicochemical water quality and environmental parameters measured in the lake’s basin. Planktothrix and Cylindrospermopsis were the dominant genera of the cyanobacterial community, while the Chlorophyceae, Chrysophyceae, and Trebouxiophyceae classes dominated the microalgae community. However, the results showed a significant temporal shift in the phytoplankton communities in Lake Cajititlán induced by the rainy season. The findings of this study suggest that significant climatic variations cause high seasonal surface runoff and rapid changes in the water quality (Chlorophyll-a, DO, NH4+, and NO3–) and in variations in the composition of the phytoplankton community. Finally, an alternation between phosphorus and nitrogen limitation was observed in Lake Cajititlán during the rainy season, clearly correlating to the presence of Planktothrix when the lake was limited by phosphorus and to the presence of Cylindrospermopsis when the lake was limited by nitrogen. The evidence presented in this study supports the idea that the death of fish in Lake Cajititlán could be mainly caused by anoxia, caused by rapid changes in water quality during the rainy season. Based on our review of the literature, this is the first study on the phytoplankton community in a subtropical lake during the rainy season using high throughput 16S rRNA and 18S rRNA amplicon sequencing.

“…Existe una relación estrecha entre DQO y DBO, ya que el DQO evalúa el oxígeno necesario para oxidar una serie de compuestos orgánicos a través de la ruta química, entre los cuales se incluye todo lo que se evalúa como materia orgánica biodegradable en el DBO. Estos indicadores suelen estar relacionados con las descargas de aguas residuales industriales y domésticas (Varol et al 2012, Quevedo-Castro et al 2019b. De acuerdo con Metcalf (2003) las aguas residuales presentan concentraciones típicas de DBO en el rango de 110-350 mg L −1 y para DQO de 250-800 mg L −1 .…”

El crecimiento de la población y producción agrícola, junto con el incremento de la industrialización a nivel mundial han deteriorado lacalidad del agua en cuerpos de agua continentales. El objetivo del presente trabajo fue analizar las tendencias de parámetros de calidad del agua en un embalse tropical de la región Centro-Sur del Estado de Sinaloa, México, aplicando análisis estadístico no-paramétrico de Mann-Kendall. Se utilizaron datos obtenidos en cuatro puntos de muestreo en la presa El Salto, durante el período 2012-2020. Los resultados indican que la calidad del agua del embalse presenta tendencia significativa a mejorar durante el periodo analizado. El embalse mostró contaminación de materia orgánica, con concentración de coliformes-fecales superiores a los criterios ecológicos de calidad de agua como fuente de abastecimiento de agua potable y riego agrícola. Las concentraciones de nutrientes, clorofila-a y visibilidad de disco Secchi clasifican el agua entre eutrófica e hiper eutrófica.

“…The ALM reservoir (Culiacan, Mexico) is in the Humaya River basin (25°05′25″, 25°20′15″ North, 107°33′00″, 107°15′00″ West) at 186.5 m above the sea level (m.a.s.l.). The ALM dam is 105.5 m high, and 765 m long, considered one of the main sources of water for agricultural irrigation, power generation, fishing, and tourist activities [26][27][28], covering 11,354 ha and ranked tenth in Mexico according to its storage capacity [29] (Figure 1). The Humaya River basin is characterized by a warm humid climate toward the center and south, with summer rains.…”

A methodology to estimate surface water quality using remote sensing is presented based on Landsat satellite imagery and in situ measurements taken every six months at four separate sampling locations in a tropical reservoir from 2015 to 2019. The remote sensing methodology uses the Box–Cox transformation model to normalize data on three water quality parameters: total organic carbon (TOC), total dissolved solids (TDS), and chlorophyll a (Chl-a). After the Box–Cox transformation, a mathematical model was generated for every parameter using multiple linear regression to correlate normalized data and spectral reflectance from Landsat 8 imagery. Then, significant testing was conducted to discard spectral bands that did not show a statistically significant response (α = 0.05) from the different water quality models. The r2 values achieved for TOC, TDS, and Chl-a water quality models after the band discrimination process were found 0.926, 0.875, and 0.810, respectively, achieving a fair fitting to real water quality data measurements. Finally, a comparison between estimated and measured water quality values not previously used for model development was carried out to validate these models. In this validation process, a good fit of 98% and 93% was obtained for TDS and TOC, respectively, whereas an acceptable fit of 81% was obtained for Chl-a. This study proposes an interesting alternative for ordered and standardized steps applied to generate mathematical models for the estimation of TOC, TDS, and Chl-a based on water quality parameters measured in the field and using satellite images.
