The Pike River Improvements Project is a multi-phase project to control flooding, restore habitat, and develop recreational areas along the Pike River in Mount Pleasant, Wisconsin. The project is divided into 9 phases stretching over 5 miles. Construction began in 2001 and phases 1-5 are complete, with phase 6 currently under construction. The primary goals of the project are flood control, restoration of the riverine corridor and aquatic habitat, and development of a multi-use trail for recreation.

- 1. Village of Mount Pleasant – Storm Water Utility Pike River Improvements Project
- 2. Pike River Improvements Project • Project is divided into 9 phases • Each Phase is approximately ½ mile in length, stretching over 5 miles through the Village of Mt. Pleasant • Construction began in 2001 • Phases 1-5 are complete • Phase 6 is currently being constructed
- 3. Pike River Improvements Phasing • Municipal Boundary • Phase Limits • Watershed Boundary • Major Roadways

- 5. Primary Goals • Flood Control with Expansion of Flood Channel to Keep Flooding within Corridor. • Restoration of Riverine Corridor with Buffer Strips. • Restoration of Aquatic Habitat with In- Steam Habitat Structures and Improved Substrate. • Recreational Corridor Development with Trails • Water Quality/TSS Removal
- 6. Flood Control • Each Phase involves expansion of the flood channel to control floodwaters. • Three Phases (Phase 1, 4 & 9) also include large flood storage areas. • Construction of Phases 1-3 resulted in complete or partial release of floodplain restriction on over 120 properties.

- 12. Habitat Restoration • Village works closely with various biologists and DNR staff to restore habitat within the Pike River corridor. • Native prairie and wetland plantings are typical throughout the corridor with annual monitoring and invasive species control. • Reconstructed stream provides more natural habitat (meanders, fish habitat structures, etc.). • Annual monitoring of stream conditions (UWM) conducted to monitor impact of to-date construction and plan for future Phases.
- 19. Recreational Corridor Development • Over 4 miles of multi- use, off-road bike trail constructed to-date throughout the corridor. • Trails are open to the public year-round. • River corridor provides wealth of additional passive and active recreation opportunities. • Unlimited access to the river.
- 20. Water Quality/TSS Removal • Water quality ponds constructed throughout the corridor at points of in-flow of runoff. • Newly constructed flood channel banks with gentle (4:1) slopes and upland vegetated buffers. • New development and re-development must meet NR 151 requirements.

- This graph displays the Fish Biotic Integrity (IBI) within areas of the Pike River that were Restored and compares it to areas that were Unrestored (between the years 1990-2009). The mean Fish Biotic Integrity observed within the Non-Restored areas of the stream Red Line The mean Fish Biotic Integrity observed within the Restored areas of the stream Green Line The marked difference between the Restored and Non-Restored is shown in the Relative Improvement Purple Line This graph shows that the restoration applied to the Pike River was having a positive effect on the Fish Biotic Integrity.
