Monday, December 28 - Streamflow: Drought + Diversions = Extreme Harm: Although recent rains have provided normal precipitation for this time of year, the long-term rainfall measurements are still well below average. The low streamflow between storms (sample map from Dec. 14 at right) that we have seen for the past half year will return unless we continue to get at least average amounts of precipitation in the form of rain or melting slow that occurs slowly enough to soak into the ground.

For a good analysis of stream problems across the state, see this press release from Pomperaug River Watershed Coalition (PRWC). Here is a key quote:

The September and October low river flows demonstrate that rivers were not supporting the critical flows needed for a healthy river habitat. In fact, sections of the Weekeepeemee River had dry river beds and the Pomperaug River was flowing only at a rate of 15% of the critical flow requirement. DEEP officials confirmed that they would expect fish mortality to increase significantly during such conditions.

Meanwhile, parts of Coppermine Brook in Bristol were drawn down to rocks and dirt, as shown in the photo below taken Dec. 11 in Bristol. The sandy ditch in the foreground is the stream channel. Bristol Water Company and New Britain Water Company have eight registered diversions near Coppermine or its tributaries with a combined registered water withdrawal of 36.6 million gallons per day (source: CT DEEP). Company representatives report they do not withraw anywhere near that much water. Bristol Water says they stopped pumping from their well near this photo for a day but with no apparent effect on the stream. This is a perennial stream with a state Trout Management Area below where this picture was taken. Click on the photo for a full-screen version in a new tab.

Update from Mon., Nov. 30, 2015: Long-term low flows continue.

Since our last Know Your Flow! update, streamflow between storms has continued to be well below normal for most of our rivers and streams. On Nov. 30, 90% of them were flowing at rates lower than 75% of all records for that date (it was 84% on Nov. 18). Of those, most were actually lower than 90% of their average daily flow for the date. Only 5 of the 52 USGS stream gages on their CT map were reporting flows anywhere near normal, and even those were below average. Click here for the Nov. 30 USGS CT streamflow map; click the map to the right for the current conditions. The color code is explained on the USGS page.

Much of what rain we have received lately has fallen as heavy downpours. Much of this runs off instead of soaking into soil to become the groundwater that keeps streams flowing between storms. Although flows obviously rise during and after storms, they drop rapidly when groundwater levels are low (see groundwater discussion below). Smaller upland streams dry up faster than the larger rivers (see the graph below). According to the National Weather Service Advanced Hydrologic Prediction Service at this link (choose CT from the state drop-down list to see current data), most of the state is still getting roughly half of normal precipitation, whether measured in one-month or many-month time scales.

Total rainfall would have to be well above normal and fall at light to moderate rates to begin to make up for the precipitation deficit that is affecting our streams and rivers. Hopefully the long-term forecast that predicts 3 or 4 inches of rain in the next couple weeks will prove accurate, because that would would actually be near or even above normal for December. 

Whenever there is a powerful storm, watch for flooding! Flash flooding can easily take people by surprise after dry periods. Remember, if water is across the road, Turn Around, Don't Drown! See below for general flooding information.

Many public water systems have asked for restrictions on water use (see below). Fortunately for water companies, heavy rain does get captured by reservoirs, and this is why reservoir capacity did not drop as fast as the flow in more free-flowing streams, but even they are beginning to see the effects of the long dry spell (discussion below). Unfortunately, even during low flows, local flooding can occur (also below) when a heavy rain hits unusually dry ground.

Is this a true drought? The U.S. Drought Monitor weekly map for Nov. 24 labeled almost all of CT as "D1-Moderate Drought" that affects 3.4 million CT residents. This is the highest percentage in this category for any Northeast state. Rhode Island is the only other Northeast state that is 100% drought-affected, but they are only "Abnormally-Dry." Most of CT has seen these moderate drought conditions for the last two months. Most or all of the state has been abnormally dry for six months. Even general news media are starting to notice.

The NWS Climate Prediction Center's three-month prognostication issued mid-October gives equal chances for normal or above average or below average precipitation. These forecasts have said nearly the same thing for most of the past six months, yet we actually consistently got less than normal.

Groundwater: Streamflow between storms depends on groundwater levels. The water under the ground (aquifer water) flows downward and comes back to the surface in streams and wetlands. A low-flow stream drains water from the ground in most cases, but if the ground is exceptionally dry the flow may reverse. An occasional brief, powerful rainstorm does not do much to help groundwater levels rise. The rain falls faster than the ground can absorb, and thus much of it becomes stormwater runoff. Real-time data on groundwater in Connecticut is available from 7 monitoring wells run by the US Geological Service (USGS). There has been slight improvement recently. All the wells are showing slight rises recently in the water table instead of the stready drop they displayed previously. On Nov. 30, "only" 2 of the 7 were at levels lower than any for the past few years of data. The other five were all lower than 75% of their records. The data are even more striking because the records cover only the last 6 to 12 years, when prolonged dry spells were already common.

Public Water Supplies: At the end of August, the CT Department of Health (DPH) issued a letter to public water systems in which they cautioned them to:

... keep a watch over the groundwater levels and surface water levels, assess the current capacity to maintain adequate supply & pressure, and as necessary institute water conservation plan and/or measures in order to effectively reduce water consumption. You may want to consider enacting voluntary water conservation measures while our state continues to be within the present weather situation.

Reservoirs provide about 2/3 of our water supply. According to the October 2015 - Monthly Reservoir Status Summary from the CT Department of Public Health, the public water supply reservoirs of the largest water companies averaged 70% full. That report states that Bristol Water is down to 60% usable storage and has issued mandatory restrictions on water use. Aquarion Water Company is asking its customers to voluntarily conserve water and stop nonessential outdoor water use. Southington reported 30% usable storage, the lowest in the list, but its website says it has withdrawn their request for voluntary water restrictions. Several other companies are lower than usual: New London Dept. of Public Utilities reported 35% (no restrictions), Second Taxing District City of Norwalk - 43% (no restrictions), CTWC - Shoreline Region-Guilford System - 47% (no restrictions), New Britain Water Department - 52% (no restrictions), Middletown Water Department - 54% (no restrictions), Norwalk First Taxing District - 56% (voluntary water conservation), Waterbury Water Department - 58% (no restrictions), Regional Water Authority - 59% (no restrictions). 

UConn's water department has issued mandatory conservation measures. The Manchester Water Department website reported 66% capacity as of Nov. 9, and the same page says they would issue an Alert at 80% and an Advisory at 70%. We have listed websites for many of the hundreds of water systems below if you want to check for water restrictions. Other water restriction sources include your town's website, your health district, and news outlets.

On Sept. 21, 2015,  40 out of 53 (74%) of our ranked rivers and streams had less water flowing in them than 75% of their recorded flows for the date. 25 of those were lower than 90% of all their records, 8 were lower than all records for that date.

This graph plots the rate of flow on Sep 4 as a percentage of the median for each stream gage. For example, a dot at the 40% line means that stream that day was flowing at 40% of what could be considered normal for that date. The few rivers and streams flowing at or above 100% of their median rate are mostly those with flows managed by dam releases.

More about our rainfall: At the beginning of July, regular rainfall brought most of our rivers and streams back to the normal pattern of varying above and below the average flows measured for any particular date (see an explanation for this below). However, below-normal rainfall has caused a steady decrease in steamflow punctuated by occasional spikes in the flow rates from storms. Our total rainfall has been below normal for a long time. The last 90 days, 180 days, even back to last October shows why we are still experiencing long-term near-drought conditions. It is the long-term rainfall totals that control groundwater levels, which in turn keep streams flowing between storms.

Some General Flood Information: When floodwaters fill the part of the stream channel that is called a floodplain, the water may find that someone has built a building or two in the channel. The water then saturates and fills any leach fields, often flushing untreated sewage out into the flow.

The floodwaters also find these really nice holes in the ground called wells to flow down into. All kinds of interesting things can be delivered to the bottom of the well, such as the aforementioned sewage, and soil, bugs, leaves, pesticides such as weed killer and insect poison, even the dog droppings from the backyard.

Very important: Any well that was flooded should be pumped and flushed out thoroughly and the system sanitized or "shocked."

The Connecticut Department of Health website has a good guide called:

Flooding: Information for Homeowners About Private Wells, Sewage and Clean-Up

Also, there are places in Connecticut where the storm drains and the sewage pipes are combined into one system. With high rainfall, many of these combined pipes are designed to overflow into rivers and streams so the wastewater treatment plants are not overwhelmed. You really do not want to be downstream when raw untreated human sewage is entering the water. The DEEP has a map of Combined Sewer Overflows that shows the six urban areas where these can occur. Zoom in to any of them to see exactly where the combined flow may enter streams and rivers. Not every rain event is enough to cause these overflows, but it's a good idea to avoid contact with the water downstream from them after significant rain.

Unless you are an expert paddler, do not attempt to canoe or kayak on floodwaters; there are usually one or two fatalities per year. Our Connecticut Water Trails website and the webpages of the many paddler groups in the state all have good safety procedures.

As the graphic to the right illustrates, where a storm moves across the state, the streams show flows that peak above their averages for this time of year but then quickly drop. The streams that maintain healthy flows between storms are those draining the parts of the state where there has been decent rainfall or those controlled by managed dams.

How quickly the flow drops after each rainstorm is unique for each stream, because it depends on how much water soaked in to increase the groundwater baseflow. In watersheds with lots of impervious roads, roofs, parking lots, patios, and compacted soil in lawns, a lot of the rain typically flows over the surface or through storm drains directly into the streams, leading to flooding problems far more often than in watersheds with mostly natural surfaces. Their streamflow then drops quickly after the storm ends, and the flow levels off far lower than in streams whose watersheds have more natural surfaces.

What IS Normal?

The National Oceanic and Admospheric Administration (NOAA) uses a rolling 30-year average of modern rainfall data to calculate its "normals." A discussion of the 1981 to 2010 precipitation calculations can be found at http://prism.oregonstate.edu/normals. To see Connecticut's average annual precipitation, go to http://prism.oregonstate.edu/gallery/view.php?state=CT_RI.

Recently there has been much discussion of what constitutes a "100-year-storm" or a "50-year storm." These traditional terms can be misleading unless you keep in mind they are an old-fashioned way of describing probablities. A "100-year" rainfall event means that in any year there is a 1% chance of that rate of rainfall.

Here is a map showing that in Connecticut we have a 1% chance of getting 7 to a little over 8 inches of rain in a 24-hour period, depending on where you are in the state. (Image source: http://precip.eas.cornell.edu/)

Comparing this to Table 7.2 (copy below) of the CT Stormwater Manual, we note that the design criteria for managing runoff possibly should be updated if we are building our landscape to control the flow from a 100-year-storm.

Water Conservation tips

Water Conservation is not just for droughts; it is important because:

  • It saves money and energy

  • It insures the reliability of your water supply

  • It protects our natural resources

What Can I Do?

  • Set a voluntary water use reduction goal of 10% (whether served by public water systems or private wells)

  • Cut back on unnecessary water use, such as watering lawns or washing cars

  • Cooperate with your local water utility and follow their plans

Model Water Use Restriction Ordinance (PDF, 28KB)

Connecticut's Draft Drought Management Plan is being updated by the CT Water Planning Council Advisory Group Drought Plan Work Group.

*On the USGS Stream Gage map, streams lower than their 10th Percentile and have records longer than 30 years are indicated with a maroon dot. We choose rivers for our low-flow list by looking at all rivers and streams Most Recent Instantaneous Value compared with their Minimum Average Daily flow and their 25th Percentile rate. Those with a flow rate closer to their Minimum than to their 25th Percentile get added to the list.
