Creek, Spooner Engineering – North, February 1980 Report presented findings of an inspection and HEC-6 (Scour and Deposition in Rivers and Reservoirs) modeling of erosion along Pheasant Br. Creek. A streambed profile for Pheasant Branch Creek from Lake Mendota to USH 12 was also presented. Modeling completed for the study determined that the sediment moving into the system from upstream of urban area is clay and silt. Clay and silt move through the entire system under all but lowest flow conditions. Erosion of creek banks in urbanized area is releasing sand into creek, which collects in Pheasant Branch Marsh. Implement the following three-year program to repair erosion: Year 1: $175,000 for repair of Century Avenue drop structure Year 2: $21,000 for engineering studies and design Year 3: $196,000 for construction of sediment basin in Pheasant Branch Marsh Study 190.

Report of Foxrdige/Stricker Pond Park Drainage Study, John Vorhees, Feb 16, 1988 This report summarizes an investigation into the cause of an existing flooding problem at the lower part of Westfield Drive caused by backup of storm sewer that discharges to Stricker Pond. Thy hydrologic and hydraulic analysis revealed that it was not a submerged outlet, but rather inadequate pipe capacity in “sub-basin C” causing the aforementioned flooding. The report concludes that some water is probably bypassing the grates of the undersized pipe, and then ponding and lowest point on Westfield Road. However, the report concluded that although upsizing the pipe may alleviate the problem, that it was not feasible, due to cost and space constraints Conduct a through investigation of pipe and grate capacity in sub-basin C Analyze the detention performance of Stricker Park Pond Clean all catch basins, pipes, and inlets on a regular basis, and rigorously enforcing erosion control regulations. ---PAGE BREAK--- City of Middleton, Wisconsin Stormwater Report Summary MSA Professional Services, Inc., April 2006 PAGE - 4 - Study Summary Recommendations Status Study 216. Esser Pond Watershed Stormwater Management Study, Warzyn Engineering, May, 1988 Evaluates stormwater management alternatives for the Esser Pond watershed, including: The practicality of limiting increased runoff from urbanization through the use of infiltration basins The effects of anticipated urbanization and encroachment on water level fluctuations The effects of an outlet from Esser Pond to the South Fork of Pheasant Branch should not produce noticeable incremental erosion of bed or banks of Pheasant Branch Creek, as the discharge rate will be trivial relative to discharge rates resulting from urbanization. Increase in water levels in the range of 1.5 to 2.5 ft above existing elevations would not have substantial adverse impacts on the wetland community, however fluctuating water levels and/or extended elevated water levels of 3 feet or more may have a negative impact on wetland vegetation. DNR analyses indicate that the 100-year floodplain elevation for Esser Pond is controlled by overflow flooding from the South Fork of Pheasant Branch Construct a 36”-diameter, 1,000’ long CMP outlet at elevation 929.5, connecting the pond to the South Fork of Pheasant Branch. Implement a water quality control program, including control of fertilizer, pesticide, herbicide and road salt application. Study Esser Pond Analysis and Design, Warzyn Engineering, August 22, 1989 This report provides revised recommendations for the Esser Pond outlet configuration and watershed management strategies based on updated projections of watershed land use, and various stormwater and ecological management criteria. Objectives: Minimize adverse wetland impacts by limiting pond level fluctuations and implementing other management strategies Minimize impacts on Pheasant Branch Creek by limiting peak discharge rates for storms up to the 10 – year event Conclusions: The Esser Pond outlet shown on Drawing 13719-1 (not included in file report) provides a good compromise in achieved stormwater management, floodplain management, and wetlands preservation performance goals. 100-year flood levels in Esser Pond are currently controlled by overflow from Pheasant Branch Creek. When these overflow conditions are eliminated through construction of the Pheasant Branch Flood Control Plan, a conservative 100-year flood stage for Esser Pond will be elevation 933.0.

Simulation of the Effects of the Effects of Hypothetical Residential Development on Water Levels in grabber Pond, Middleton, WI, Leo B. House, USGS, 1993 This study documents the development of a calibrated hydrologic model of the watershed tributary to Graber Pond. The model was used to evaluate the effects of urban development on the annual change in water level and on the 100-year overflow volume. Results predicted a significant change between then-existing and fully developed planned land conditions. Results also predict that without the then- existing significant inflow of industrial effluent the pond would periodically dry up. None N/A Study 217b. Hydrologic Study of Graber Pond Watershed for the City of Middleton, Jim Bosma (UW CEE Master Degree Project), December 7, 1996 This report documents a study with the stated objective of assisting the WRMC in managing Graber Pond watershed by through the development of a user-friendly hydrologic computer model. The model would allow staff to evaluate various management scenarios aimed at meeting the following management goals: Pond does not exceed City of Middleton property limits Pond does not dry up unnecessarily Pond water quality is not decreased A second stated objective of the study was to analyze soils of the pond and its watershed to determine if their infiltration capacity can be increased. Review of existing soils survey data revealed that all the watershed’s soils belong to hydrologic soil group B. This report also documents finding of a hydrologic model commissioned by the WRMC to investigate the impact of the potential loss of cooling water discharged from Springs Inc. At the time of the study, about half of the total inflow to Graber Pond was industrial cooling water discharge. However, water conservation concerns promoted the WRMC to recommend that the industry begin recycling water, which would result in a 90 percent reduction of inflows from th4e facility to the pond. The City did not want the pond to dry up and part of the purpose of the study was to investigate whether the potential reduction in effluent inputs would periodically cause the pond to dry up. Also noted in the report is that in 1993 the pond completely filled-up, overflowed onto adjacent property, and over-topped the berm constructed by the City to prevent overflow from exceeding City boundaries. Acquire the land specified in the 1981 Master Plan for Development solely for hydrologic purposes. The proposed acquisitions (in figure 17 of the aforementioned plan) should be obtained to insure that Graber Pond’s surface area is within the City of Middleton boundaries instead of removing the berm built in 1993. Construct a sedimentation pond within the proposed acquisition to trap nutrients and help control nuisance growth of algae and macrophytes during the summer and fall. Construct an overflow infiltration trench with the proposed overflow acquisition. Modify the existing overflow weir to include a small orifice that leads to the infiltration trench Study 218, Report #1 Flood Control Planning Study – South Fork Pheasant Branch Creek, Middleton WI, Warzyn Engineering, Inc., July 1988 This report appears to be an abbreviated version of Report See study 218 Report #4 N/A ---PAGE BREAK--- City of Middleton, Wisconsin Stormwater Report Summary MSA Professional Services, Inc., April 2006 PAGE - 6 - Study Summary Recommendations Status Study 218, Report #2 Revised Floodplain Analysis – South Fork Pheasant Branch Creek, Middleton, WI The report documented development and results of HEC-2 and DAMBRK models developed to evaluate previously ignored effects of storage within Esser Pond.

A shallow observation well near Middleton’s Municipal Well #6 showed fluctuations in water table to be likely caused by pumping the deeper municipal well, suggesting, that there is some connection between the shallow and deep ground- water regimes. None N/A Study Hydrogeology of Dane County, Wisconsin Geological and Natural History Survey, October 1, 1999 This report provides a detailed description of the geology and groundwater conditions in Dane County. Significant findings include: “Recharge is non-uniform across the county and varies spatially from about 0.2 to 13 inches per year, averaging about 5 in/yr. Recharge usually occurs on the higher parts of the landscape along the crests and flanks of broad ridges and along steep wooded slopes. Lower areas of the landscape are more often areas of groundwater discharge.” “Steady-state zones of contribution show that some wells produce water originating as recharge up to 10 or 15 miles away while others produce water originating very near the well.” “50-100 year zones of contribution are generally several thousand feet to a mile in length [distance from well] and represent more appropriate areas for groundwater protection” None N/A Study Groundwater Protection Plan, Dane County Regional Plan Commission, July, 1999 This report identifies and characterizes potential groundwater contamination risks (sources, locations, etc), and provides recommendations to reduce these risks.

The report identifies a decline in the watertable in the vicinities of lakes Mendota and Monona of more than 60 feet between pre-settlement and 1992. For the City of Middleton the average reduction in groundwater elevations averages approximately 10 to 20 feet. None N/A Study Evaluation of Alternative Management Strategies, Dane County RPC, August 1997 This report presents the findings of activities undertaken to achieve goal three of the 1992 Study Design for Dane County Regional Hydrologic Study and evaluates various management strategies for mitigating ground and surface water impacts based on the results of regional groundwater and reservoir-routing computer model simulations conducted by the USGS. The report concludes that the mean annual flow in the Yahara River has been reduced by approximately 33% as a result of historic groundwater pumping and wastewater diversion. The report predicts an additional 34% reduction unless offsetting management strategies are implemented. The report offered several findings the most significant of which are: Surface water discharge of treated effluent to Nine Springs Creek would offset the effects of 2020 pumping and land use as well as result in a 65% increase in Yahara system streamflows (relative to 1992 flows). Complete cessation of diversion in the Yahara River basin through surface water discharge of treated effluent could offset the effects of 2020 pumping and land use, increase flows 76% (relative to 1992 flows), and nearly recover predevelopment streamflows. Treated effluent return of wastewater generated in the Upper Sugar River basin could increase baseflows in Badger Mill Creek and offset both past and future baseflow declines.

Wetland and Vegetation Design and Management Plan for Stricker’s Pond The file contained a proposal by James H. Zimmerman, consulting ecologist, to prepare a Wetland and Vegetation Design and Management Plan for Stricker’s Pond, dated December 30, 1991. The proposal outlined three goals: Enhance stormwater management to reduce hazards of flooding and decrease of water quality, Promote support of wildlife and its attendant educational opportunities, Enhance aesthetics either through the addition of flowering marsh plants or increased open water. Minutes for the February 12, 1992 meeting of the Water Resources Management Commission show that the WRMC endorsed the findings of the study and recommended initiation of a three-year wetland monitoring program. After monitoring period concludes, a reevaluation was to be completed to determine whether phase 2 of the project would be implemented. Minutes from the joint meeting of the Public Works Committee/Park, Recreation & Forestry Commission held on Monday April 13, 1992 indicated that a consensus was reached that the Park Commission would take the responsibility for overseeing the Stricker Pond project. Implement an ‘information and education plan’ and that includes an inventory, monitoring, and educating neighbors and local schools regarding the project for a minimum period of three years. Actively manage stormwater runoff and contaminants in the watershed, including possible alteration of the drainage and conveyance systems serving Stricker’s Pond, and incorporation of native plantings to increase plant and animal diversity. ---PAGE BREAK--- City of Middleton, Wisconsin Stormwater Report Summary MSA Professional Services, Inc., April 2006 PAGE - 12 - Study Summary Recommendations Status Study 229.

A large population of minnows was also observed including brassy, bluntnose, and fathead minnows. Brook stickleback were also observed.” None N/A Study 239. Esser Pond Study (Wetland and Trail Design), 1995 The file contains a proposal by Eco-Systems Design dated February 14, 1995 outlining activities required to obtain the baseline environmental conditions of Esser Pond. Total cost of the proposal was $3,850. Minutes from the February 15, 1995 WRMC meeting included a discussion of the proposal. The minutes indicate that consensus was, although sedimentation basins could be constructed upstream of the pond, they would probably have only minor affect on improving the water quality and that active measures to control pond elevations were probably not feasible. Commission member Gebert pointed out that the outlet was designed to minimize the fluctuations of the pond surface elevation, taking into account full development. He suggested that the first phase of the proposal be limited to data collection in the areas of soils, vegetation and surrounding land use as a significant amount of hydrologic data was already available.

The report included a comprehensive inventory of possible pollution sources: Barnyard Runoff – Estimates indicated that approximately 75% of 20,064 pounds of phosphorus generated by farm animals is delivered to Lake Mendota. Nutrient Management Inventory – a. Nutrient management plans were prepared for 36% of all cropped acres in Dane County and 40% of all cropped acres in Columbia County – a total of 5,500 acres. b. 50% of farmers apply nitrogen at levels above those recommended by the University of Wisconsin. 70% of farmers apply phosphorus in excess of crop removal rates. Streambank Erosion Inventory – Approximately 728 tons of sediment erodes annually from streambanks in the watershed; approximately 7.5% of the watershed’s total load. Approximately 4,608 pounds of phosphorus are delivered annually with the eroding soils to surface waters. Upland Sediment Inventory – An estimated 35,197 tons of sediment is delivered to streams from cropland on an annual basis. Approximately 6,589 tons of which are delivered to Lake Medota. Wetlands Inventory – Approximately 4,301 acres of prior converted or restorable wetland exist within the watershed. Groundwater Inventory – 65% of drinking water wells within the watershed are above 10mg/l in nitrates, the threshold for the Enforcement Standard Health Advisory Level. Urban Inventory – SLAMM model results show that 8,626 tons of sediment are delivered to watershed streams from the five largest municipalities surrounding Lake Mendota (including Middleton). 4,675 tons of sediment and 25,813 pounds of phosphorus are delivered to the Pheasant Branch and Cherokee Marshes. 3,281 tons of sediment and 17, 651 pounds of phosphorus are delivered to Lake Mendota annually. Lake Modeling – Average total phosphorus loading to the lake was calculated to be 75,000 pounds per year. The report identified a goal of reducing phosphorus loads to Lake Mendota by 50%. The report also identified a wetland restoration objective including the Pheasant Branch Creek Resource Protection Area. The primary means by which this goals was to be met was through improved management of barnyard facilities and cropland. Activities in urban areas includes the requirement to reduce total suspended solids loads by 40% for existing urban areas and 80% for new development. Study 241.

Dane County Water Quality Plan – 1995 The Dane County Water Quality Plan was originally developed and adopted in 1979. The plan was updated and revised in 1990 and 1995 to reflect changes in local, state, and federal programs and regulations. A third revision was prepared in 2004 at the request of the WDNR and reflects the implementation of some of the priority recommendations and actions of the 1995 plan. The file contained a copy of the 1995, 1979 and 2004 Dane County Water Quality Plans (Summary Plans). The reports provide a detailed summary of county-wide water quality conditions, both for surface water and groundwater, and makes relatively general recommendations to municipalities to develop policies for protecting these resources. Specific Priority Action plans were developed for communities within Dane County. Implement the following priority action plan elements: Implement State NR151 and NR216, and federal Phase II stormwater regulations Vigorously enforce and expand comprehensive erosion control and stormwater management requirements beyond the minimum standards of Dane County Ordinance Chapter 14. Place additional emphasis on enforcement of ordinance by hiring additional staff. Develop a city stormwater quality management and wetland protection plan. Consider creating a stormwater utility for financing stormwater management programs. Work with DNR and Dane County to implement nonpoint source programs and projects proposed in the Lake Mendota Priority Lake Project Plan. Cooperate with other units of government in developing a coordinated stormwater quality management plan for the Central Urban Service Area. Participate with DNR, USGS, Dane County, City of Madison and other units of government in an annual cooperative water resources monitoring program.

The plan recommends that the City acquire the area and develop it into a park. This report contains correspondence from the Park Commission Chair to the Mayor recommending plan adoption, and a letter from the WDNR Water Management Specialist stating that although filling of the siltation basin would not require a permit, that alternative erosion control measures are needed if the pond is filled. The plan includes a figure illustrating the listed recommendations, and a list of recommended plants. Acquire the following property: Acquire the portion of Stricker’s Pond in the City of Middleton, the ten-foot walkway and utility ROW between lots P-12 and 13, and Stricker’s Pond shoreline Fill and grade the existing sediment basin northwest side of the pond and convert area to a youth playfield. Improve lots P-34 and P-35 as street frontage for the playfield Construct a 6’ wide asphalt-surfaced bike and pedestrian path extending from the main park entrance on Voss Parkway around the playfields to Westfield Road and along the north side of Stricker’s Pond to Middleton Street. Establish a non-surfaced primitive hiking trail around the western perimeter of the pond. Manage the pond to function as a stormwater basin, wildlife habitat and passive reaction facility Carefully review all plans for adjacent development for linkages to Stricker’s Pond Develop and management playfields and youth facilities serving the neighborhood only. Middleton Parks Commission should meet periodically with Madison Parks Commission to assure park development is coordinated with adjacent Madison park development. Study The Effects of Deicing Salt Usage on Surface and Ground Water Quality, R. Laurence Davis, Alfred University (New York), July 1982 This report documents a studying analyzing the impact of road salt on ground and surface water quality in the rapidly urbanizing Town of Penfield, NY. The findings are that there has been a significant reduction in the quality of both surface and ground water in the town that is attributable to heavy use of de-icing salts on the roads, to the extent that it does not meet legal standards. Reductions in the amount of salt applied has reversed the trend in rural parts of town, and to a lesser extent, in the urban parts of town. Study results suggest it is beneficial to minimize de-icing salt application rates. Study - A Report from the North Fork Pheasant Branch Watershed Committee, March 1999 This report describes the natural history of the Pheasant Branch Watershed, and the need for measures to improve the North Fork. The report includes a Middleton City Council resolution date March 1999 supporting the efforts of the North Fork Pheasant Branch Watershed Committee. Reconfigure the existing drainage channel into a wide, meandering, multi-leveled flood terrace that is vegetated with native plant species and designed to accommodate stream spillover during heavy storms. Conduct studies of potential wetland restoration sites to determine their suitability and where possible, restore wetlands to reconstruct hydrologic functions lost long ago when large portions of the Pheasant Branch flood plain were drained. Implement the 1999 recommendations of the Master Plan for the Pheasant Branch Conservancy as they pertain to protection of ecological resources in the Marsh and Watershed. ---PAGE BREAK--- City of Middleton, Wisconsin Stormwater Report Summary MSA Professional Services, Inc., April 2006 PAGE - 18 - Study Summary Recommendations Status Study Effects of Urbanization on Streamflow, Sediment Loads, and Channel Morphology in Pheasant Branch Basin, Near Middleton, WI, USGS, July 1986 This report documents the development and results of a model simulating the effects of effects of partial and complete urbanization on streamflow, sediment loads, and channel morphology in Pheasant Branch Basin. Simulation results indicate that urbanization increases flood peaks, and the increased channel widths and depths. None N/A Study Use of a Waterhsed-Modeling Approach to Assess Hydrologic Effects of Urbanization, North Fork Pheasant Branch Basin near Middleton, WI, USGS, 2001 This report documents the development, calibration, and results of a coupled ground-surface water model for Pheasant Branch Watershed, to assess the hydrologic effect of urbanization on the North Fork. The study simulated two development scenarios. Sceanario A represents low-density residential, and scenario B- development is 50 percent commercial and 50 percent medium- density residential. Under scenario A mean annual streamflow was increased by 53 percent, and baseflow decreased by 14 percent. Under scenario B, runoff increased by 450 percent, and reduces stream baseflow to zero. The model was then used to assess the effect of urbanization on streamflow, and groundwater recharge, and the potential of three detention sites to mitigate the predicted flow rates: West of Capital View Raod North of Schneider Road North of Highway K Together, the simulation predicted that he three ponds were able to decrease scenario A peak discharge rates below the current rate during large storm events. The report does not include any specific recommendations but results suggest that the City should investigate regional detention to minimize the risk of increased channel erosion due to increased peak discharge rates. Results also suggest that infiltration practices and/or reduced development densities are necessary to maintain the North Fork’s baseflow. ---PAGE BREAK--- City of Middleton, Wisconsin Stormwater Report Summary MSA Professional Services, Inc., April 2006 PAGE - 19 - Study Summary Recommendations Status Study Inventory and Evaluation of Opportunities for Retrofitting Stormwater Best Management Practices, Jennifer Koehler UW-Madison Civil and Environmental Engineering, September 2005 This report documents an investigation of the suitability of various City parcels for siting stormwater infiltration and/or water quality practices serving existing developed areas. Evaluated parcels included public open space more than 1200 ft from a municipal well, and with a mapped soil permeability greater than or equal to 0.6 inches per hour were analyzed with the model Infiltration Patch (IP).
