This data describes past monitoring of dissolved oxygen concentrations on a continuous basis using Hydrolab® water quality monitoring equipment in the Puyallup River, as stipulated in the 1998 Agreement on the Allocation of the Puyallup River TMDL (Total Maximum Daily Load) Reserve Capacity of Biochemical Oxygen Demand and Ammonia. The Puyallup River TMDL prepared by Ecology in 1993 set a maximum load for BOD5 at 20,322 lbs./day and a maximum load for ammonia at 3,350 lbs./day (Pelletier, 1993). The TMDL includes a reserve capacity of 3,670 lbs./day of BOD5 and 1,200 lbs./day of ammonia in the Puyallup River basin. In 1996, Ecology initiated a mediation process to establish a strategy for managing the reserve capacity. This resulted in the Agreement (1998) which establishes the reserve allocations for point sources and Indian Tribes, articulates the process for accessing and managing the reserve allocations, and sets the terms for implementation and monitoring.
