What is a drought?
A drought occurs when a region experiences below-average precipitation over an extended period, resulting in low stream flows and low surface water and groundwater levels. Drought classification occurs in levels. Please visit the United States Drought Monitor page to learn more about these levels.
The following is a brief overview of the different levels.
Level 0 - Abnormally Dry (no restrictions)
Level 1 - Moderate Drought

City of Lebanon Water Works Facts
The following are facts about the City of Lebanon waterworks.
- The City of Lebanon water system uses approximately 3-5 CFS* to meet its water demand. Ninety-nine percent of the time the flow leaving Mascoma Lake is greater than 15 CFS*. Mascoma Lake supplies the Lebanon Water Treatment Plant to produce drinking water.
- Lebanon waterworks produced 553 MG* of water in 2021. Peak day demand was 2.35 MG*.
* Terminology
MG= Million gallons
CFS= cubic feet per second
How Can You Help Mitigate Drought Conditions?
You can do the following to help mitigate drought conditions in our area.
- Cutting out non-essential water use and using water more efficiently during a drought are significant means of mitigating drought conditions.
- Abide by water restrictions implemented by your municipality or public water system and consider recommendations made by state agencies.
The following are things you can do to conserve water.
- Cut out non-essential uses such as outdoor water for lawn, car, and pressure washing.
- Conserve water by cutting back on shower times, only doing full loads of laundry when necessary, and turning off the faucet while brushing teeth, doing dishes, and washing hands.
- Replace old water fixtures and appliances that are wasting water. Top-loading washing machines built before 2003 and toilets older than 1994 are known to be the largest water-wasting culprits in the home. Showerheads older than 1994 can also waste a great deal of water, as can older bathroom sink aerators. Selecting ENERGY STAR® certified machines and replacing old water fixtures with EPA WaterSense-certified fixtures is an easy way to ensure you choose products that will save water and perform. For guidance on selecting ENERGY STAR® and WaterSense-certified products and more water efficiency tips, see the NHDES water efficiency fact sheets.
- Fix leaks, including running toilets. Running toilets can waste hundreds of gallons a day. Old and worn toilet flappers are often the culprit and are very easy to replace. Also, some toilet leaks can’t be heard. Check for a leak by dropping food coloring (12 drops) or a leak detector dye tablet in the toilet tank. Do not flush for 15 or 20 minutes. If the dye shows up in the bowl, you know that your toilet is running.
- Spread out the timing of water use so that multiple water uses do not co-occur and the well has time to replenish between uses. (Relevant to private well owners)
