Mud Slough Restoration Project
Document Type

Present Land Use
Wetlands, uplands, and riparian habitat
Document Description
The Proposed Project objective is to restore and enhance wildlife habitat on the China Island Unit of the North Grasslands Wildlife Management Area and on the Newman Land Company property by reestablishing Mud Slough flows to portions of those lands that were isolated from Mud Slough as a result of the Grassland Bypass Project. The Proposed Project would replace the water supplies to Newman Lake through the restoration of the hydrologic connection between Mud Slough and the Lake. Natural erosion effects of flow in Mud Slough have caused the normal water level to drop to approximately four feet below the Newman Lake water level. Therefore, hydraulic modification is required. Structures previously installed on China Island will be removed.
