Clayshulte, Principal Water Resources Planner <br /> <br />QIv <br /> <br />Re: <br /> <br />Clean Lake Study Being Conducted by DRCOG for the Bear Creek <br />Reservoi r and Watershed <br /> <br />Date: <br /> <br />June 7, 1988 <br /> <br />The Denver Regional Council of Governments (DRCOG) has begun a Clean Lake <br />Study to evaluate water quality, environmental integrity and natural resources <br />of the Bear Creek Reservoir and associated watershed. The watershed includes <br />Turkey Creeks and Bear Creek up to Evergreen Lake. The Clean Lake study <br />will provide one year of water quality data for reservoir, stream, rainfall and <br />groundwater sites. Reservoir surveys will be made to assess macrophyte coverage <br />in summer months, hydraulic surveys for various runoff periods, bathymetric. <br />mapping of bottom configurations and sediment deltas at river mouths, <br />sedimentation rates, fish distribution and tissue analysis, biological resources and <br />reservoir modeling. Water quality in the watershed will be routinely monitored, <br />sampled in peak spring runoff and during several storm events, Groundwater <br />will be characterized upstream of the reservoir in Bear Creek Park. <br /> <br />The goal of the Clean Lakes Program i~ to implement methods and procedures to <br />control sources of pollution introduced into publicly owned freshwater lakes or <br />man-made reservoirs which have recreational value. Lakes or reservoirs included <br />in a Clean Lakes study have been identified as having their uses impaired or <br />threateil"''::. Th", Phase I diagno,tic-feasibility study of a Clean Lakes Program <br />gathers comprehensive data which will be used to identify and evaluate potential <br />methods for restoring and protecting degraded lakes or reservoirs to meet their <br />intended uses, Sufficient diagnostic information about the reservoir and its <br />watershed must be collected in relation to water quality, limnology, morphology, <br />ecological relationships, demographic and socioeconomic environments. This in- <br />formation enables decision-makers to select the most feasible alternative for re- <br />storing or protecting the reservoir water quality and environment while <br />maximizing public benefits. <br /> <br />An important component of the diagnostic study is information which deals with <br />user population perceptions about the reservoir and associated watershed. The <br />Clean Lake Study requires gathering specific data which characterizes public <br />access, user population and distribution, current public benefits, recreational <br />uses, impairment of recreational uses, reactions to pollution control or <br /> <br />Boord CHicers <br />Robert L, TonSlng, Chairman <br />Roben L, PuckeM, Vice Chairman <br />Harold E.
