Drought Update

July 15, 2022



Summary


  • As a result of a low snowpack, early spring melt and below normal precipitation over the past few months, "moderate drought" has emerged across the state and "severe drought" has developed along the state's border with Massachusetts.


  • Over the past 30-days, the majority of the state received 25% to 50% of normal precipitation, intensifying already dry conditions and resulting in rapid development of drought.


  • Stream levels are low across the state and very low stream flows are apparent in the northeast section of the state.


  • The state's groundwater level monitoring network indicates a mix of groundwater levels. Of note is a unified trend of low groundwater levels along the Connecticut Valley.


  • The precipitation outlooks for July and over the next three months do not provide a strong indicator that the precipitation needed to relieve drought conditions will be received. Temperature outlooks lean toward above normal temperatures, which can exacerbate drought conditions.



The Message


  • The public, community water systems, and municipalities should begin practicing conservation. Limit outdoor watering and irrigation to before 7am and after 8pm and to even and odd days. Community water systems, as well as municipalities implementing lawn watering restrictions within town boundaries pursuant to RSA 41:11-dshould report restrictions using the online Restriction Reporting Form.
