JC BoyleFlow estimates below JC Boyle Hydro Project




PacifiCorp has discontinued posting the JC Boyle hourly release estimates for the fall, winter and spring months. PacifiCorp cannot reliably forecast JC Boyle operations during these months. This is due to a combination of continuously changing electrical demand and fluctuating stream flow conditions (due to precipitation and other factors) during this period, which result in frequent real-time changes in powerhouse operations. Thus, flow releases from the plant cannot be reliably forecasted. Recreation forecasts will resume in late spring 2019.
