“…Shifts in water temperature outside of that preferred thermal range can adversely affect the overall health of the aquatic ecosystem. High water temperatures in the range of 23-25°C have been shown to increase the mortality rates of a number of fish species (Lee and Rinne, 1980;Bjorn and Reiser, 1991;Hodgson and Quinn, 2002). Lund et al (2002) showed high summer water temperatures to be the cause of a heat-shock response in juvenile salmonids.…”

Abstract:In this paper regression models are developed for predicting water temperature and the concentration of dissolved oxygen in rivers monitored by the Newfoundland and Labrador Real-Time Water Quality Monitoring (RTWQM) network. The developed models can be used to predict mean, maximum and minimum water temperatures and dissolved oxygen at the monthly, weekly and daily time scales. A nonlinear logistic model is found to best represent the S-shaped relationship between water temperature at the real-time stations and air temperature collected from meteorological stations 5-50 kilometers away. There is a clear tendency for monthly and weekly models to be more accurate for prediction than the daily models. Both linear and nonlinear exponential decay models were found to best represent the relationship between water temperature and dissolved oxygen at the real-time stations. A novel graphical method of linking air temperature to water temperature and dissolved oxygen has been developed and may prove to be a valuable simple tool in the assessment of the health of the rivers in the real-time network.Résumé : Ce papier décrit des modèles de régression qui prédisent la température de l'eau et la concentration d'oxygène dissous dans les rivières surveillées par le réseau Terre-Neuve-et-Labrador Real-Time Water Quality. On peut utiliser les modèles développés pour prédire les températures d'eau moyennes, maximales et minimales et les niveaux d'oxygène dissous dans l'eau aux échelles mensuelles, hebdomadaires et quotidiennes. Un modèle non-linéaire logistique représente mieux la relation entre la température de l'eau aux stations en temps réel et la température de l'air provenant des stations météorologiques de 5 à 50 kilomètres de distance. Il y a une tendance claire pour les modèles mensuels et hebdomadaires d'être plus précis pour la prédiction que les modèles quotidiens. Les modèles linéaires et non-linéaires de décroissance exponentielle représentent mieux la relation entre la température de l'eau et l'oxygène dissous aux stations en temps réel. Une nouvelle méthode graphique de relier la température de l'air à la température de l'eau et l'oxygène dissous a été développée; cette méthode devrait se révéler un outil précieux et simple pour évaluer la santé des rivières dans le réseau en temps réel.

“…A large, hot wildfire, as a result of convectional heating and input of burning debris and ash, could conceivably increase stream water temperatures to a lethal level for coldwater salmonid fishes. This elevation of water temperature would have to be present only for a short (less than an hour) period of time (Lee and Rinne 1980). Although the recent Mt.…”

“…However, the life-cycle of brook trout is heavily influenced by the degree and timing of temperature changes [11,20]. High stream temperatures cause physical stress including slowed metabolism and decreased growth rate, adverse effects on critical life-cycle stages such as spawning or migration triggers, and in extreme cases, mortality [7,[21][22][23][24]. Distribution is also affected as coldwater fish actively avoid water temperatures that exceed their preferred temperature by 2-5 • C [25,26].…”

It has become increasingly important to recognize historical water quality trends so that the future impacts of climate change may be better understood. Climate studies have suggested that inland stream temperatures and average streamflow will increase over the next century in New England, thereby putting aquatic species sustained by coldwater habitats at risk. In this study we evaluated two different approaches for modeling historical streamflow and stream temperature in a Rhode Island, USA, watershed with the Soil and Water Assessment Tool (SWAT), using (i) original SWAT and (ii) SWAT plus a hydroclimatological model component that considers both hydrological inputs and air temperature. Based on daily calibration results with six years of measured streamflow and four years of stream temperature data, we examined occurrences of stressful conditions for brook trout (Salvelinus fontinalis) using the hydroclimatological model. SWAT with the hydroclimatological component improved modestly during calibration (NSE of 0.93, R 2 of 0.95) compared to the original SWAT (NSE of 0.83, R 2 of 0.93). Between 1980-2009, the number of stressful events, a moment in time where high or low flows occur simultaneously with stream temperatures exceeding 21 • C, increased by 55% and average streamflow increased by 60%. This study supports using the hydroclimatological SWAT component and provides an example method for assessing stressful conditions in southern New England's coldwater habitats.
