WIND DIRECTION (DEGREES)

49°

0° means the wind is heading towards the North; 90° towards the East; 180° towards the South; 270° towards the West

Show Map

WIND SPEED

0.089m/h

Higher wind speed promotes the mixing of the water, and promotes an exchange between the water and the air. Higher winds also help push debris towards the shoreline.

AIRTEMP

60.4°F

Warm air warms the water, which encourages algae growth

RELATIVE HUMIDITY

92

Relative humidity describes the amount of water vapor in a mixture of air and water vapor.

BAROMETRIC PRESSURE

1012

Higher pressure is generally associated with clear weather. An average range is 980 to 1050.

RAIN (15 MINUTES) (MM)

0

More rain yields more river flow and increased mixing.

SUNLIGHT (UMOLSM2)

50.56

Sunlight encourages algae growth. This reading can range from slightly negative to 1500 on a sunny summer day.

Lake Lillinonah Bouy Data

DO BOTTOM

5.10

Dissolved Oxygen readings are generally lower in lake bottoms, due to decomposition of organic matter and lack of air contact.

BOTTOM TEMP

70.9°F

Cooler water at the bottom of the lake indicates stratification of the lake water.

SURFACE TEMP

72.2°F

Warm water encourages algae growth

SP COND

362

Measures the ability of the water to conduct an electrical current. Specific Conductance is directly related to the concentration of dissolved ions in the water. An average range in Lake Lillinonah is 280-320. Significantly lower values suggest dilution from heavy rain.

PH

8.32

Lake acidity, determined by measuring the concentration of Hydrogen Ions. pH in Lake Lillinonah is affected by the composition of bedrock in the watershed as well as the balance between photosynthesis and respiration within the lake.

DO SURFACE

8.63

Readings above 6 are healthy for fish; between 5 and six indicate moderate impairment; below 5 indicate severe impairment and mortality.
