Johnson Co. Soil & Water Conservation District
Location
 Johnson County, IA
 21,645 acres
 Flows into a impaired
segment of the Iowa
River that is listed on
the 2004 Iowa 303(d)
list for excessive
indicator bacteria.
Watershed Development & Planning
Assistance Grant
 March 2008-March 2009
 JCSWCD Partners with
JAICWC
 Water Sample Analysis
 Streamside
 Bacteria
 Land Use Assessment
 RASCAL Assessment
 Preparation of Grant and
Watershed Plan
Land Use Assessment
 Mobile GIS tablet
 Windshield Survey
Land Use Map
 Row Crop – 50%
 Timber – 16%
 Urban/Residential –
16%
 CRP –13%
 Pasture – 4%
 Wetland –0.1%
Sediment Delivery
 RUSLE (Revised
Universal Soil Loss
Equation)
 Estimated Sediment
Delivery – 10,166
tons/year
 Estimated Sheet & Rill
Erosion – 50,875
tons/year
Contribution to Impairments
 Cattle Access to Creek
 Poor Manure Management
 Poorly maintained or non-
existing septic systems
 Two unsewered communities
 Sedimentation of the creek
