Residents who frequent Loveland Reservoir are again raising alarms about water being drained from the area’s largest public open-space reservoir. The concerns come three years after the reservoir was lowered to deadpool levels, killing off the fish population and severely impacting recreation. … Anglers say the fish population was just beginning to recover from the previous draining. … Residents also worry the lower water levels will affect firefighting resources. … A spokesperson for Sweetwater Authority confirmed the agency is conducting controlled water transfers to “continue providing safe and reliable water to our South Bay ratepayers.”
