The Planning team focuses on the future of the watershed supplies, demands, water quality improvement, potential new sources of water, and coordinating the numerous agencies that work with or are affected by water, wastewater, and related activities. Major aspects of the team's work include major multi-agency water quality programs (e.g., TIN/TDS), facilitation of regulatory programs (e.g., Lake Elsinore & Canyon Lake Nutrient TMDL), and administration of other major programs (e.g., the Lake Elsinore/San Jacinto Watersheds Authority- LESJWA).
