Ross School and St. Anselms monitored early in the school year. However, it should be noted that criteria for any single parameter listed in any publication as adequate for steelhead or any other species should be considered cautiously. For example, the dissolved gas equilibrium for oxygen and carbon dioxide in water are dependent on atmospheric pressure and water temperature. However, since all fish and aquatic invertebrates are cold-blooded, their metabolic requirements for oxygen increases with the temperature of the receiving water. All schools should report their data throughout the year.
Early fall is a critical time for steelhead, because the water is seasonally the warmest.
Friends would like to ensure that all schools monitor in the late summer and early fall to learn whether there is good habitat for juvenile steelhead.
