Water from a natural wetland area along the San Juan floodplain is diverted through a box culvert and then flows through the new ponds and wetlands via stream channels and returns to the San Juan. Excavation and shaping of the ponds, wetlands, and channels was done by Ajacs Construction of Albu-querque and Bloomfield, NM. The project involved approximately 110,000 cubic yards of earthwork. Erosion control was modest in scale, largely because the site was nearly flat and most exposed slopes drained into the ponds. Approximately 40,000 native wetland plugs were planted in the moist soil and shallow water zones and spread rapidly across the site, providing excel-lent erosion control. The drier upland areas were seeded with native grasses and covered with straw mulch that was crimped with a disc. The spillways between ponds were constructed with large natural stone. The final discharge spillway is an adjustable box culvert. The project design and construction oversight was done by Chris Philips of Riverbend Engineering, with offices in Durango, CO, and Albuquerque, NM. Project management from the New Mexico Department of Game and Fish was provided by Marc Wethington, who has managed the fishery along the San Juan for 21 years. This year he received the Lifetime Achievement Award from the American Fisheries Society (also known as the Fish Head of the Year Award) for his numerous habi-tat restoration projects and successful fisheries management of this remark-able trophy fishing water. Revegetation work followed as soon as the ponds and channels were filled to normal operating levels. Thirty species of native wetland sedges, rushes, bul-rushes, and grasses were planted along the shorelines of the ponds and stream channels using nursery-grown plugs from Hydra Aquatic Inc. of Albuquer-que. Hydra also installed container-grown cottonwood trees, five species of willows, and six species of native shrubs in the areas adjacent to the ponds. The desired wildlife habitat and rec-reational opportunities have exceeded expectations, as have the positive com-ments the Department of Game and Fish has received from the public. The public support inspired a second project downstream, just above the Hammond Reservoir irrigation diversion. A small diversion flowed into a channel that led to a pond and wetland area. The pond then drained by a discharge channel back to the San Juan River. Fish habitat improvements were made in the river channel itself at this site, including a large stone weir that created a pool with eddies on both sides. The design phase has been com-pleted for a third project upstream of the Munoz Flats area. Construction for this project is currently awaiting fund-ing approval.
