  1. Temperature • Animals in the stream can only tolerate a certain temperature of water at different stages of their life cycles. • Sagehen Creek is between 5-13 C or 41-55.4 F. This temperature range supports the Lahontan Cutthroat Trout, Piute Sculpin, Stoneflies, and Caddisflies. Temperatura • Animales en el arroyó solamente pueden soportar cierta temperatura de agua en diferentes estados de sus vidas. • La temperatura del arroyó en Sagehen está entre 5-13 C o 41-55.4 F. Esta temperatura sostiene al Lahontan Cutthroat Trout, Piute Sculpin, Stoneflies y Caddisflies a sobrevivir. ¿Puede existir vida en este arroyó? A Healthy Stream How can you tell if a stream is healthy? You can tell by taking some tests. Three items that test the health of the stream are temperature, pH, and dissolved oxygen. Temperature measures the warmth or coolness of the water. pH tests whether the water is basic or acidic. Dissolved oxygen checks the percentage of oxygen in the water available for aquatic life to breathe. As you read on, you will see how healthy Sagehen Creek is. ¿Cómo sabe si este arroyó es salubable? Puede tomar pruebas para saber. Tres cosas que puede examinar son la temperatura, las partes de hidrógeno (pH) y el oxígeno disolvido. La temperatura mide lo frío o caliente del agua. Las partes de hidrógeno examina si el agua es ácida o básica. El oxígeno disolvido mide el porcentaje de oxígeno que existe en el agua para que la vida aquatica respire. Continua y aprende mas. Dissolved Oxygen pH • Plants process the air outside of the stream and introduce oxygen into the stream through their roots. Dissolved oxygen can also enter the stream through fast moving water that flows over rocks. • The trout, sculpin, caddisflies, and stoneflies in this stream need a higher level of dissolved oxygen to breathe. When the stream temperature goes up, it holds less oxygen. • Without high levels of dissolved oxygen aquatic life starts to die. • pH is important for aquatic life. If the water in the stream is too acidic or too basic, it will harm aquatic life. The desired range is between 6.5 and 8.2. Sagehen Creek is about a 6.5. • Rocks that get broken down and enter the stream affect pH, which determines how acidic or basic the water is. Partes de Hidrógeno (pH) Oxígeno disolvido • Partes de Hidrógeno (pH) son importantes para la vida aquática. Si el agua en el arroyó es muy acida o muy basica puede a dañar la vida aquática. Las partes de hidrógeno mejores para la vida es entre 6.5 y 8.2. El arroyo en Sagehen tiene un pH de 6.5. • Piedras que se quebran y entran al arroyó afectan el pH. • Plantas procesan el aire afuera del arroyó e introducen oxígeno por las raíces. Oxígeno disolvido también puede entrar al arroyó por agua que se mueve muy rapido y se va sobre piedras. • Lahontan Cutthroat trout, Sculpin, Stonefliy y Caddisfly necesitan un nivel mas alto de oxígeno disolvido para respirar. Cuando la temperatura del arroyó sube, el nivel de oxígeno disolvido baja. • Sin niveles altos de oxígeno disolvido, la vida aquática empieza a morir.
