The objectives of this study were to investigate 1) the effects of sedimentation and temperature on the use of streambed cover as a velocity refuge by juvenile brook trout in simulated winter flood conditions and 2) the effects of sedimentation, temperature, and time of day on cover use and social interactions of brook trout cohorts in low flow summer water conditions. Using artificial stream channels, experiments were conducted with wild juvenile brook trout collected from the North Fork Tye River, Nelson County, VA. Brook trout did not use streambed cover as a velocity refuge during winter flood simulations. Generalized linear mixed models were used to analyze cohort low flow conditions with sedimentation, temperature, and time as fixed effects and cohort as a random effect. Streambed cover use decreased significantly as temperature and sedimentation increased (p
