basin. Though the report agreed with long-standing ideas and proposals of local flood mitigation and ecosystem protections, the introduced options were also based on financial and timelines costs, as well as funding and community willingness. The alternatives included a dam and reservoir in Pe Ell, levee and dike builds, the purchase of land to create "non-structural flood protection", or allowing the upper basin and floodplain to return to a more natural state, allowing natural processes to prevent future flood issues. The most expensive options could cost as much as $ 1.8 billion, despite the report noting that a failure to reduce flooding in the basin over a 100-year span could potentially lead to $ 3.5 billion in losses.
409:. Known as the Chehalis River Basin Flood Damage Reduction Project EIS, it proposed over 60 alternatives to flood control methods in the basin and it included impact studies of a dam build. Plans of a redesigned, non-traditional dam were released in August 2024 which included a new location in Pe Ell to minimize effects on indigenous lands. The reservoir was reduced by 32 acres (13 ha) and the pass-through structure designed to simulate the river bed and flow of the waterway. The revised dam incorporated several design changes due to a variety of concerns from prior studies and protests, such as protection of aquatic and vegetative habitats, recreation access to the river, and potential disruption to Pe Ell's water supply..
394:, a cultural staple of the indigenous people. The nation has proposed alternatives for a water retention system, with a focus on repairing habitats for native species of fish. With approximately 75% of tribal lands in the basin considered floodplain, the Chehalis and Quinault communities created a flood plan in 2009 that avoids structural and engineered systems to control flooding, rather using natural elements and ecosystems that would focus on "river movement, flooding and erosion, rather than confining the river or changing its flows." An addendum to the plan was released in 2020, adding in a concentration on the buying-out of private and commercial properties in the floodplains.
364:. One was to be located near Boistfort, Washington and the other in Pe Ell. Though the Boistfort dam did not materialize, the CBS has continued to propose the Pe Ell dam that would temporarily be used as a reservoir to withhold excess runoff during heavy rainfall or snowmelt situations. As of 2020, the structure was planned to be 270 feet (82.3 m) in height and was to be built in a canyon located in forest lands used for commercial timber harvest. The project, if constructed, was estimated to lower 100-year flood waters in the Twin Cities by over 1.5 feet (0.5 m) as well as protect 25% of buildings that were at-risk during a major flood event.
425:, a species thought to be extinct in the area, a cooperation between the non-profit Capitol Land Trust and a landowner purchased 60 acres (24 ha) around the Blooms Ditch tributary in order to establish a habitat for the amphibian. Along with an additional acquisition of 60 acres (24 ha) and over 4,000 feet (1,219.2 m) of the ditch, the project created the Blooms Preserve. Fourteen Chehalis Basin Strategy partners combined to control invasive plants, the construction of ponds to hold water throughout the year, and the planting of native vegetation, while continuing to improve the
150:(USGS). Specifically used to track the depth of the waters, it was run in conjunction with the county. In 2010, the flood authority implemented the installation of an online flood warning system available to residents in the Chehalis basin. Known as the Chehalis Basin Flood Warning System, it expanded a sensor network already in place, providing information on rainfall and temperature, as well as additional gauges. Alert warnings are sent via email and provide information on 13 rivers in the area. The system won the 2023 National Hydrologic Warning Council (NHWC) Operational Excellence Award.

401:, in July 2020. With growing concerns over the negative aspects the dam would have to the natural ecosystem, the authority, strategy, and connected partners and government entities were required to find alternatives to the dam, specifically non-structural, natural remedies that would protect the watershed's aquatic habitats. The directive allowed the groups time to propose such alternatives in time for the 2021 state legislature session, and asked that communication and participation with tribal communities be improved. During the same year, the

in the 1870s, and a subsequent increase in timber harvesting due to the new rail systems, denuded forest land around the
Chehalis River led flood waters to be mostly contained in deeper valleys and channels. Though some floods continued to occur, they were sparse enough that flood control measures were considered too costly and unnecessary. Development in the floodplain began in the early 1900s, and by the late 20th century, floods became more severe and more numerous.

Skookumchuck conversion is seen as an unlikely part of flood control in the Chehalis-Centralia area, as well as the downstream affects on the Chehalis.
70:. The commission focuses on flood control and river health, as well as habitat restoration, with particular attention to native plants, fish, and other aquatic species. It partners with various non-profits, local organizations, Native American communities and tribes, and other state and federal government agencies, often through its program, the Chehalis Basin Strategy.

Additional concerns were broached, focusing on habitat concerns, such as the necessary removal of 90 percent of trees in the holding area and issues of salmon survival due to potential increases in water temperatures, the loss of spawning areas,
371:. During a retention period, fish trapped in the reservoir would be caught and transported to the other side of the dam. Studies of the build of the dam has been determined it to be of positive economic value to the region as major flooding events would be significantly reduced while protecting infrastructure and various populated areas.

The dam would also create a loss of use for recreation, such as kayaking and fishing. The dam is predicted to provide little downstream benefit to communities in
