Pk ~.. ~ ..~._..e .~ - ~ ~ ~ ~. a, a . I ~ - ,, ~ - _~ ~ The primary pollutant of concern in urban lakes is phosphonts. This pollutant enters lakes from the watershed through stormwater, which contains fertilizers, yard waste, and other organic materials. There are also internal sources of phosphonts, such as lake sediments and aquatic plants. Excess phosphonts results in Increases in nuisance summer algae blooms i Decreases in water transparency, or clarity Shifts in fish species from desirable game fish to nongame species The results of a RWMWD shtdy (?005) found that residential streets, driveways, and sidewalks, as well as freeway right-of-ways and railroad right-of-ways, account for more than half of the total annual phosphonts loading to the r District's surface waters. ~~ Exotic invasive plants and large amounts of sediment can also contribute to water quality problems. - -_ - ~-- Poor w. u~ ~ ~, ~ ~ ~r ity rs often indi~_~ : << d by nzisance algae growth-the rpszrlt of excess plzosphortts in a lake. Page 5 GOAL: PROMOTE QUALITY SURFACE WATER ACHIEVE HEALTHY ECOSYSTEMS PROVIDE FOR FLOOD CONTROL SUSTAIN QUALITY GROUNDWATER EDUCATE AND INVOLVE CITIZENS MANAGE ORGANIZATION EFFECTIVELY Future water quality improvements will require the involvement and action of property owners, including residents, businesses, and builders/developers. This creates a strong demand for a comprehensive watershed education program that reaches multiple target audiences with multiple educational messages. The RWMWD will carry out the following tasks in an effort to protect and restore the quality of the District's water resources: • Complete, or assist in completing, total maximum daily load (TMDL) studies, as needed • Complete and implement SLMP studies or other water quality studies on Round Lake (Maplewood), Round Lake (Little Canada), Twin Lake, Wakefield La1ce, and Willow Lake • Implement water quality studies-Phalen Chain of Lakes SLMP, Carver Lake SLMP, Beaver Lake SLMP, and Battle Creek Lake Watershed Management Plan (see Part LB. of the Resource and Organizational Assessment) • Continue water quality montoring to assess lakes, streams. and watershed outlets, and to measure project performance (see Part ILA. of the Resource and Organizational Assessment) • Expand water quality monitoring to assist local communities with National Pollutant Discharge Elimination System (NPDES) Phase II Municipal Separate Storm Sewer Systems (MS4) permit requirements to detect illicit discharges to stormwater systems • Implement and maintain long-term monitoring and research for on-site water management techniques constructed at the RWMWD office building site • Identify gaps in knowledge related to the water quality of RWMWD managed lakes and streams and proceed with appropriate actions to address these gaps • Assist ill funding research specifically targeted to challenges within the RWMWD • Keep RWMWD staff current on new and im~ovative techniques for water resource management • Continue aggressive maintenance of RWMWD improvement projects • Expand RWMWD collaboration efforts with cities and counties to assist in the implementation of appropriate technologies and maintenance practices for improving water quality • Expand use of innovative water quality improvement products, equipment, and methods as necessary to address sites with limited land area for conventional treatment techniques • Continue implementing and updating the RWMWD permitting program • Incorporate the new RWMWD standards into the District's permitting program • Encourage' individuals to implement water quality improvement practices at their homes, businesses, and public places • Develop and implement methods/programs for measuring, tracking, and reporting progress towards achieving water quality goals Ramsey-Washington Metro ~7r Distri~
