    The recapture of reusable return flows will affect flow patterns and yields in the South Platte RiverSome farmers will exercise their property rights to use, transfer, lease or periodically fallow historic agricultural water usesCities must pay for water rights, infrastructure and mitigation but the total cost must be absorbed in affordable municipal rate structuresCities must work with rural communities can effective local/ 1041 regulations shape the future? Can workable relationships be developed for the benefit of both entities?
