Population, Land Use

The city of Janesville is a medium-to-large-sized urban center located along the main stem of the Rock River. Portions of the city fall in the Rock River/Milton Creek watershed (LR04), Blackhawk Creek watershed (LR02) and the Bass Creek watershed (LR03). In year 2000, the City of Janesville grew to a population of 59,500, a 6% growth rate from 1995 to 2000. A 1993 population analysis by the city of Janesville predicted the year 2000 population at 57,600 (an underestimate of nearly 2,000 people) at a growth rate of about 1 percent per year. Like many other metropolitan area, Janesville is experiencing migration from the city to the suburbs and outlying rural areas. Densities in the city have gradually decreased as more land has been annexed and the population has grown. The city is now in the process of updating its sewer service area plan to reflect shifts in urban/suburban growth.

Ecological Landscapes for Rock River - Milton Watershed

Ecological Landscapes

The Southeast Glacial Plains Ecological Landscape makes up the bulk of the non-coastal land area in southeast Wisconsin. This Ecological Landscape is made up of glacial till plains and moraines. Most of this Ecological Landscape is composed of glacial materials deposited during the Wisconsin Ice Age, but the southwest portion consists of older, pre-Wisconsin till with a more dissected topography. Soils are lime-rich tills overlain in most areas by a silt-loam loess cap. Agricultural and residential interests throughout the landscape have significantly altered the historical vegetation. Most of the rare natural communities that remain are associated with large moraines or in areas where the Niagara Escarpment occurs close to the surface. Historically, vegetation in the Southeast Glacial Plains consisted of a mix of prairie, oak forests and savanna, and maple-basswood forests. Wet-mesic prairies, southern sedge meadows, emergent marshes, and calcareous fens were found in lower portions of the Landscape. End moraines and drumlins supported savannas and forests. Agricultural and urban land use practices have drastically changed the land cover of the Southeast Glacial Plains since Euro-American settlement. The current vegetation is primarily agricultural cropland. Remaining forests occupy only about 10% of the land area and consist of maple-basswood, lowland hardwoods, and oak. No large mesic forests exist today except on the Kettle Interlobate Moraine which has topography too rugged for agriculture. Some existing forest patches that were formerly savannas have succeeded to hardwood forest due to fire suppression.

Please note: Final report deliverables help us ensure that the grant has been satisfactorily completed, and that state dollars are being spent wisely. Every deliverable, no matter how minor, must be completed in order to receive full reimbursement for the state share of costs. Ranking questions used to obtain this award, and specific deliverables mentioned in your grant description, constitute final report deliverables. If any deliverable is not adequately provided in the final report, only partial reimbursement, at the department's discretion, will be made. The only exception will be if there is a well-justified and department-approved scope amendment. If you have any question about what a specific ranking question or other deliverable means, please contact your river coordinator BEFORE you sign this agreement.

Rock River - Milton WatershedWatershed History Note

The western half of the City of Milton is located within the Rock River - Milton Watershed. In 1844, Joseph Goodrich, who founded Milton, built and founded Milton Academy, originally a high school, which evolved into Milton College. It eventually grew to encompass 16 buildings and encompass over 24 acres. Its music department was renowned, and the student body was culturally diverse. For 138 years it was a prestigious private institution until financial troubles caused it to close in 1982. It had been the oldest college in the State of Wisconsin. Today, several of the college buildings have been converted into antique shops, offices, apartments, and the city library.
