WMA projects are already in operation at eight ranches in the Northern Everglades. Four were constructed and operational in 2007, and an additional four were constructed and operational by early 2010.

Ranch Name	Ranch size (ac)	Water Management Alternative (WMA) type (service area)	WMA Design and Operation and Purpose
Alderman-Deloney Ranch	3,353	Wetland water retention of on-site water sources (322)	Two culverts with riser structures installed in drainage ditches to retain water at set elevation in two natural depressional wetlands. Maintain water at higher stage than was possible previously.
Buck Island Ranch	10,494	Pasture water retention of on site-water sources (3,748 acres)	Thirty-six culverts with riser structures installed in network of drainage ditches to reduce P runoff and retain water in the ditches and subsurface inside 3,703 of agriculturally improved pasture. Maintain water at higher stage than was possible previously.
C. M. Payne and Son Josephine Road Ranch	783	Pasture water retention of on-site and off-site water sources (367 acres)	Existing culverts and newly installed culverts and berms to retain water in pastures; water includes both on-site rainfall and runoff from upstream developments. Maintain water at higher stage than was possible previously
Lightsey Cattle Co. XL Ranch	3,230	Pasture water retention of on-site water sources (364 acres)	Install culvert-riser board water control structures and several intervening fixed plates with bleed down holes in pasture drainage ditches to attenuate pasture runoff, maintain higher groundwater levels and increase water storage on-site.
Lykes Bros., Inc.	342,247	Nutrient removal from off-site water sources pumped into existing marsh impoundment (2,368 acres)	Hydraulic pump to take water from regional public canal (C-41a) into existing 2,368 acre marsh/impoundment with gravity outflow at the downstream end. Nutrient removal from public water.
Rafter T Ranch, Inc.	5,074	Pasture water retention, water impoundment area and wetland water retention of on-site water sources (1624acres)	a. Use existing berm along Arbuckle Creek to maintain higher water levels in pastures and drainage ditches; b. constructed impoundment to retain water pumped from adjacent pastures with gravity flow into creek; c. culvert riser board structure installed to retain more water in existing cypress swamp.
Syfrett Ranch	3,062	Pasture water retention of on-site and off-site water sources (2197 acres)	Use existing infrastructure of pumps and ditches to retain more water on pastures planted with flood-tolerant grass; pump water from regional canal onto flooded pasture for retention during wet periods.
Williamson Cattle Co.	9,094	Wetland water retention of on-site water sources (659 acres)	Install water control structure at discharge of wetland area that was ditched and drained ~40 years ago. Maintain water stage at higher level than was possible previously to provide water retention.
