This basin master water control manual describes the overall water control plan for the Alabama-Coosa-Tallapoosa (ACT) River Basin. Descriptions of the basin, history of development, water control activities, and coordination with others are provided as supplemental information to enhance the knowledge and understanding of the basin water control plan. This manual provides a general reference source for ACT water control regulation. It is intended for use in day-to-day, real-time water management decision making and for training new personnel.

The National Integrated Drought Information System (NIDIS) is pleased to share our 2021 Annual Report to provide insight into the many accomplishments of the program over the previous year and the opportunities that lie ahead.

Quarterly Climate Impacts and Outlook for the Southern Region for December 2021–February 2022. Dated March 2022.

Winter 2021–2022 temperatures were near normal across western Oklahoma and western and southern Texas. In the rest of the Southern Region, average winter temperatures ran about 2°F to 4°F above normal. The northern half of Arkansas, all of Tennessee, parts of northern Mississippi, and isolated portions of Texas experienced above-normal precipitation during winter 2021–2022. Elsewhere, it was quite dry.

Quarterly Climate Impacts and Outlook for the Western Region for December 2021–February 2022. Dated March 2022.

Above-normal temperatures were observed in mountain regions in California, Colorado, Arizona, and Oregon. Despite a wet December, high pressure-induced dry conditions during January and February created widespread below-normal conditions throughout the West.

Quarterly Climate Impacts and Outlook for the Northeast Region for December 2021 - February 2022.  Dated March 2022.

The Northeast's winter average temperature was 0.7°F above normal, ranking in the warmest third of all years. Six states had one of their 20 warmest winters. The Northeast saw 88% of normal winter precipitation, ranking in the middle third of all years. This winter was among the 20 driest for four states.

Quarterly Climate Impacts and Outlook for the Missouri River Basin for December 2021–February 2022. Dated March 2022.

Winter temperatures were above normal for the majority of the Missouri River Basin. Precipitation was mostly below normal in the mountains and plains. The exception was eastern North Dakota with well-above-normal precipitation and snowfall. Many counties in northern Kansas and Nebraska ranked among their driest winters on record.

Quarterly Climate Impacts and Outlook for the Great Lakes Region for December 2021 - February 2022.  Dated March 2022.

Winter ranged from 1°C (2°F) below normal in parts of Maine to 3°C (5°F) above normal in Cape Breton, N.S. Warm winter temperatures are a concern for Nova Scotia's Christmas tree industry. Winter precipitation ranged from 75% of normal to 175% of normal.
