About Maquoketa Headwaters
- Maquoketa headwaters is a 40,073--acre
watershed delivering its water to the lake at Backbone State Park.
- The Iowa Department of Natural Resources
maintains the coldwater portion (9.2
miles) below Iowa Highway 3 as a "put and take " trout fishery.
Richmond Springs, a 1.2 mile coldwater
trout stream and the lower 3.7 miles of the river above Backbone
Lake are in public ownership. Eighteen species of fish have been identified
in the Maquoketa Headwaters and most are typical
of Iowa ’s coldwater streams. A recent
angler survey reported 34,675 fishing trips with annual fishing expenditures
estimated at $1,664,000.
- Eighty percent of the watershed is in crop
production. Eighty-eight of the 219 farms have
livestock operations. Nutrient runoff and sediment are significant nonpoint
source concerns.
- A goal of the Maquoketa Headwaters project is
the development of a strong watershed organization
committed to watershed/community planning.
What is a water quality project?
- An opportunity for those who live in or have a
stake in Maquoketa Headwaters watershed to voluntarily determine the future
of the area.
- A process that will lead to local decisions
about ways to protect soil and water quality that
are practical and cost-effective.
Why is a water quality project important?
- A locally--led project demonstrates that the
watershed community can evaluate and set their
own goals and standards for environmental protection and economic
development.
- It is your opportunity to manage your water
resource..
- If we don ’t address water quality issues in
Maquoketa Headwaters today,someone else will
likely do it for us tomorrow.
How is a water quality project accomplished?
- Invite all watershed residents and landowners
to participate in this project.
- Together,assess watershed conditions and
options.
- Develop strategies to improve the Maquoketa
Headwaters watershed.
- Implement strategies.
- Measure success.
What can you do as a citizen?
- Think about what clean water means to
you,,your family,your business,your schools, churches
and others in the Maquoketa Headwaters area.
- Get involved!! Learn about the options. Come
prepared to join your neighbors in setting watershed goals – and make them
happen.

About the
Maquoketa River
- The Maquoketa River watershed
is 1,879 square miles or
1,198,754 acres.
- The watershed has a population
of 61,048 people (1990
census). The watershed is predominantly rural
with the largest communities being Monticello (3,522),Maquoketa
(6,130)and Manchester (5,137).
- The Maquoketa River system is
made up of 3,011 miles of rivers and
streams of which 1,218 miles are continually flowing.
- Iowa DNR estimates that there
are 199,482 annual fishing trips with angler
expenditures and resulting economic activity of $18,487,880 per year.
- The Maquoketa River Basin is
listed as a Number One Priority on the 1998 Iowa Unified Watershed
Assessment, Restoration Priorities and Restoration Action Strategies.
- Land use in the Maquoketa
River Watershed is predominantly agricultural ((92%),timber (6%)and
urban (2%).
- It is estimated that the
watershed has 4,250 farms with 3,200 livestock operations.
Environmental Concerns
- The Maquoketa River is one of
13 tributaries of the Mississippi River that is being monitored
by the Long-Term Resource Monitoring Program and results have shown that the
Maquoketa has the highest level
of suspended sediment and plant nutrients.
- Each year the Mississippi
River carries 1 million tons of sediment as it enters Iowa. USGS
data show the Maquoketa River contributes an additional 1/2-million tons.
- The average total nitrogen
is 6.6 milligrams per liter (mg/L) with subwatersheds up to
19.6 mg/L.Ten mg/L nitrate nitrogen is the EPA criterion for domestic
water supplies.
- The average phosphorus
level is 0.4 mg/L with subwatersheds up to 4.7 mg/L. Algae grow
increasingly better in water over 0.05 mg/L phosphorus.
- The North Fork Maquoketa River
is one of the more erosive watersheds in eastern Iowa. On
a scale of 1 (least erosion) to 10 (most erosion), North Fork subwatersheds
rank from 7 to 9.The
headwaters region near Luxemburg has a rank of 9.Whitewater, Lytle,
Mineral and Bear creek subwatersheds of the mainstream Maquoketa have a
rank of 8.
- A 7,000--square mile hypoxia
zone has been identified in the Gulf of Mexico. Hypoxia occurs
when high concentrations of plant nutrients causes excessive growth of small
aquatic plants (phytoplankton)
which die throughout the summer consuming oxygen during
decomposition. The dissolved oxygen in the Gulf water becomes depleted
resulting in displacement
of aquatic life,including fish populations.
Environmental Management
Rather than farms or rural
communities being visited by regulators, more flexibility in addressing
surface and groundwater quality can be achieved when citizens participate
in the development of practices and
solutions.
