Figure 11, Appendix A also shows the surface water/groundwater interaction as analyzed by <br />regional screening performed by the Metropolitan Council in their report, Evaluation of <br />Groundwater and Surface -Water Interaction: Guidance for Resource Assessment. The Council <br />intends on completing this process again in the future as new information becomes available. A <br />majority of the waterbodies on the western half of the City have been shown to recharge aquifers. <br />2.8. Hydrologic System and Data <br />Stormwater runoff generated from the City of Hugo is directed to three different watersheds. <br />a. The north and south portions of the City are directed north into Hardwood Creek, the <br />southwest portion of the City is directed west into Clearwater Creek. Both Clearwater and <br />Hardwood Creeks are directed west into the Rice Creek Chain of Lakes and are contained <br />within the Rice Creek watershed. This stormwater runoff is directed to the west, eventually <br />outletting into the Mississippi River. The total area of Hugo contained within the RCWD is <br />approximately 31 square miles. <br />b. Approximately four square miles of southeastern Hugo drains east into north and south <br />School Section Lakes, which are in the Brown's Creek Watershed. This stormwater is <br />eventually conveyed to the east, outletting into the St. Croix River. <br />c. Approximately one square mile of east central Hugo is directed to the east into Big Marine <br />Lake. This portion of the City is contained within the Carnelian -Marine Watershed District. <br />Figure 12, Appendix A shows these subwatersheds and flow paths as well as the RCWD's <br />boundaries for designated Resources of Concern. <br />The RCWD has completed watershed -wide hydrologic and hydraulic models that includes the <br />City of Hugo as part of their District -wide Modeling Program. These models include SWMM <br />models for public drainage systems into Rice Creek, direct drainage into Rice Creek, water <br />quality models, Future Conditions Modeling, and a HEC-RAS model of Rice Creek. The City <br />currently has a signed License Agreement dated May 20, 2016 for the use of the RCWD's <br />models. The City will regularly coordinate with the RCWD to data -share any updated component <br />of the models. <br />The City has reviewed model assumptions and accepts the model outputs as a part of City <br />modeling data. The City is responsible for the use of the RCWD's models. The City intends to use <br />the models for assessment of floodplain alterations as part of Rule E, peak rate requirements and <br />intercommunity flows for Rule C, project design and permitting, identification of flood prone areas, <br />and for sizing stormwater infrastructure. Hugo will continue working with RCWD on future <br />management of model input data to ensure RCWD and Hugo have consistent information for <br />future projects. <br />Figure 13, Appendix A shows the City's stormwater infrastructure including storm sewer, <br />stormwater pond locations, and MS4 outfalls. <br />2.9. Public Areas for Water Based Recreation and Access <br />Water based recreation within the City of Hugo includes swimming, fishing, and boating. Lakes <br />within the City include Oneka, Bald Eagle, Egg, Horseshoe, Sunset, Long, Barker, Plaisted, Round, <br />and School Section Lake. Oneka, Bald Eagle, and Sunset Lakes have public water access; the <br />other lakes have private water access. <br />SECTION 2 <br />
