Grant funds expended and/or projected through June 2015
Spokane and Whitman counties adopted the final Hangman (Latah) Creek Watershed Management Plan in September 2005. Phase 4 implementation started in October 2006, and the detailed implementation plan was completed in early 2008. Some of the plan recommendations include:
The planning group partnered with WRIAs 34 and 54 to conduct a geophysical orientation survey on the West Plains, where the water table is declining. After completing the detailed implementation plan in early 2008, the planning group moved forward on its stream gaging strategy. They installed a stream gage at the state line and in mid watershed, worked on a habitat restoration strategy, and took part in developing TMDLs for Hangman Creek. They also completed a stream restoration project at Rock Creek in Rockford.
The Town of Rockford received funding to replace its leaky water storage tank, and upgrade its irrigation system to improve water conservation. The WRIA 56 group has more recently conducted groundwater monitoring including installation of several wells for long term data as well as sampling for water quality and age-dating. That study has been extended into the lower valley and into the West Plains area and is being coordinated with WRIA 54 monitoring activities.
Instream flow status
The planning group completed an instream flow study to evaluate stream flow conditions primarily for fisheries. They developed flow recommendations for three levels of habitat protection, but could not achieve consensus before plan adoption.
The planning group continued to work on instream flow recommendations during 2008, and is closer to reaching consensus. They have agreed conceptually to a minimum instream flow, but want to develop recommendations for managing groundwater (specifically domestic exempt wells) before requesting Ecology to begin rulemaking.
Significant growth is anticipated in Lower Hangman, within Spokane County, and increased use of domestic exempt wells for single and group homes is anticipated. Given the absence of any well monitoring network in the watershed and lack of data about groundwater, the planning group sought funds to:
Much of this work has been completed or is currently in process.
