4. ASSESSMENT OF PROBLEMS AND ISSUES Outlined below is an assessment of existing and potential water resource -related problems that are known at this time. These problems have been identified based on an analysis of the land and water resource data collected during the preparation of this plan and through information provided by the City, its residents, and the watershed organizations. A description of any existing or potential problem within the City has been listed and potential future corrective actions have been incorporated into an implementation plan. Refer to Figure 7, Appendix A for the location of many of the problem areas discussed below. 4.1. Judicial Ditch #2 and Judicial Ditch #3 Problem 4.1.A Judicial Ditch (JD) #2 and Judicial Ditch #3 require ongoing routine maintenance. Corrective Action 4.1.A The City of Hugo entered into a MOU with the RCWD regarding the maintenance of JD #2 in 2017, which expires in 2021. The City will work with the RCWD to retain that agreement. The City is also interested in assuming minor maintenance responsibilities of Judicial Ditch #3. The City will work with RCWD on additional measures needed. 4.2. Water Quality Problems Problem 4.2.A Within the City of Hugo, degradation in surface water quality has been noted at Bald Eagle Lake, Peltier Lake, and Hardwood Creek. Corrective Action 4.2.A A TMDL has been completed for Bald Eagle Lake, Peltier Lake, and Hardwood Creek. Waste Load Allocations (WLAs) as part of the implementation plans associated with each TMDL will be followed to improve existing water quality problems. The Bald Eagle Lake TMDL assigned the City of Hugo a WLA of 125 pounds of total phosphorus (TP) per year (47 pounds direct from Bald Eagle and 78 pounds associated with JD #1). The Hardwood Creek TMDL allocates 8,000 pounds per year of phosphorus reduction for all MS4 entities that contribute to the creek. The City was not assigned a specific numeric goal but must show progress towards helping to achieve the overarching 8,000 pounds per year goal. The City will continue to administer their stormwater management ordinances to meet the requirements of this TMDL and will collaborate with RCWD to complete streambank restoration projects identified in Table 6-1. The Peltier TMDL lists a reduction of 943 pounds of total phosphorus per year. Similar to the Hardwood Creek TMDL, the Peltier Lake TMDL lists the City of Hugo as one of a number of MS4 entities which contribute to Peltier Lake and as such the City must contribute to the overall reduction goal. To meet these TMDL requirements, the City has created the Capital Improvement Plan for Stormwater Projects (Appendix D), which contains the following projects: • Oneka Ridge stormwater reuse system contributed to a measured reduction of 21.5 pounds per year of phosphorus in 2015. This system has been constructed. This project helps meet TP reductions for the Bald Eagle Lake TMDL. • Beaver Ponds was constructed the summer of 2016 and has an expected phosphorus reduction of 9.2 pounds per year*. This project helps meet TP reductions for the Bald Eagle Lake TMDL. SECTION 4 ' . •
