The following is an update from Jerry Jackson of the Waste
Treatment Plant concerning the lake levels as of March 2nd, 2009
By early February the lake siphon brought the level down about 6
inches. The melt off and rain since then have brought the lake back
to where it was and then some.
Rainfall is 2.65 inches above normal for 2009 over the last 3 years,
there has been a 26.99 inch surplus over normal rainfall. Normal
annual rainfall is 42.27 inches.
The siphon has been operated whenever downstream conditions
(Travis Ditch level) allow.
So far, 233 million gallons have been removed, which is about 11
inches. We plan is to continue to operate the drain whenever
possible until the lake temperature reaches 50F and we have to shut
down. Typically this occurs in early April.
Our lab crew reads the downstream gauge (CR-1200 S at Travis
Ditch) every Monday and when there is a change in weather. The
Kankakee River Gauge at Davis closely tracks Travis Ditch level
and readings are available here:

When our Lake Levels Are Low:
Pine Lake is a “closed lake” in that there are no natural tributaries leading in or out
of the lake. The level of the lake is dependent on rainfall, snow runoff and runoff
from surrounding areas.
Since 1998, the level of the lakes has declined every year. Mild winters over the
last several years have not produced the normal snow accumulation. The lake does
not remain frozen through the winter which leads to continued evaporation. Our
summers over the last several years have been hot and dry, and rainfall has been
way below normal. All of these factors have taken a toll on the lake levels causing
the lake to drop close to 2-3 feet below normal.
Other factors include fluctuation in the water tables, cyclical lake levels. For
example, back in 1965 the lake was extremely low and in 1993 the lake was 2-3
feet above normal.
The Lake Association is working with other city departments in an effort to find a
means to replenish the lake and bring lake levels back to normal.

Below is some information about the low lake level in Pine Lake from Kevin
Lackman who attended the April 2006 meeting on Weed Control.
Water existing in Pine Lake already evaporates back to the atmosphere, so once
you start pumping additional water out for irrigation, and depending on the
circumstances, additional evaporation (midday watering) from turf grass watering
takes place potentially resulting in a net decrease of surface water levels. This
may be a minor issue under normal circumstances, but when you have a low lake
level this becomes more critical.
Groundwater does not evaporate, unless it’s at the surface of the land, therefore,
extracting groundwater for irrigation would be more ideal. This same groundwater,
however, is what keeps Pine Lake “wet” when it hasn’t been raining, therefore
excessive irrigation from city water could also have negative impacts on local lake
levels.
The term “groundwater drought” has been given to our area, hence contributing to
low local lake levels. One cause of this is urbanization - more hard surfaces
(parking lots, roads, rooftops, and even lawns, which are less permeable than
people realize b/c of compaction), less natural surfaces - more runoff - less
groundwater recharge.
I wouldn’t so much focus on where the irrigation water is coming from, but rather
take the following into consideration:
• Irrigate during morning hours when it’s nice & cool. Irrigating during midday
heat will result in the majority of water being lost to evaporation before plants can
even take it in, and can attract sunlight which can scald your grass (similar to a
sunburn when you’re in a pool or lake…it’s amplified…compared of if you’re not in
a body of water) Don’t water in the evening or at night, as this may promote
diseases for your vegetation.
• Utilize mulch mowers which leave grass clippings on the surface of your
yard. Not only are these clippings a source of nitrogen, but also can help to
conserve moisture in your yard.
• Irrigate predominantly during summers months (June & July), This time of
month usually entails more evapotranspiration (combination of evaporation and
transpiration) & less precipitation, meaning your soils will dry out and require
irrigation. Spring and fall month irrigation is much less critical
Irrigating from a surface water resource is legal but may not be ideal. Here are the
legal requirements of DNR Division of Water Rights & Usage:
• All major water withdrawals at or above 100,000 gallons per day must
register w/ DNR and may need to obtain permit coverage
• All permanent pumps used for water withdrawals must obtain permit
coverage
• All withdrawals that result in a lake level decreasing beneath (lakeward) its
legal lake level must be permitted (but would be hard to pinpoint and prove that a
given withdrawal caused just that)
