Title:

H: 157 - Research shoreline erosion processes and restoration results

Description:

Flathead Lake is subject to shoreline erosion from boat traffic and extended regulation of lake levels at full pool during the summer season. The erosion results in degradation of the littoral zone and an epidemic of seawall construction. "Natural" or "soft" solutions to erosion have been implemented on Flathead Lake with remarkable success. This research provides valuable data for directing the future implementation of these natural solutions throughout the lake. This work element entails research and monitoring that includes measurements of wind and wave energy, timing and duration, and change in shoreline position and particle size within the beach profile. We will conduct site-specific studies of the rate and extent of shoreline erosion in Flathead Lake, monitor restoration projects, and disseminate information about project results.

Research is currently being conducted at a site along the northeast shoreline of East Bay, Blue Bay and the Polson waterfront and we now have six years of data compiled from these sites. Our method is to install nested pairs of erosion pins into the full pool shoreline at the study sites. Erosion pins are 3’ long pieces of 3/8” re-bar fitted with plastic caps. One erosion pin is set horizontally and flush with the bank, and the other is set vertically and flush with the lake bottom. As waves erode the bank and lake bed the pins become exposed allowing a lineal measure of land loss. Conversely, if sediment is deposited the amount of accretion can be measured. Each nested pair of erosion pins is located in the field with a GPS and their position plotted on a geo-rectified aerial photograph. This system of erosion pins is measured annually.

WE Agreement Type:

Contracted

Deliverable Specification:

This project is intended to provide the raw data and evidence necessary to support future beach restoration projects to be conducted by the agencies and private lakeshore owners. We will ultimately identify shoreline cells undergoing high erosion rates and design research to correlate the erosion to wave energy and substrate type and develop potential solutions to site-specific conditions. On restored sites we quantify percent deviation in profile from the baseline established immediately following restoration.

Sort	Type	Title	Start	End	Status	Modified By	Modified Date
A	EC	Environmental compliance requirements complete	10/1/2012	12/28/2012	Concluded	Barry Hansen	7/17/2012 3:50:45 PM
		Description: On-the-ground work associated with this work element cannot proceed until this milestone is complete. Milestone is complete when final documentation is received from BPA environmental compliance staff (completion can be based on pre-existing environmental documentation from BPA).
B	PUBPROTOCOL	Review, revise, and Publish protocol, study design, and methods in monitoringmethods.org	10/1/2012	12/28/2012	Concluded	Barry Hansen	7/17/2012 3:50:45 PM
		Description: The Protocol (including temporal and spatial design) and Methods for this work element are stored at monitoringmethods.org and need to be finalized (i.e., "Published" through monitoringmethods.org), preferably prior to data collection. Preparations for contract renewals must include reviewing any previously published Protocols/Methods to ensure that they are consistent with how work will be done in any subsequent contract.
C		Coordinate subcontract with University of Montana	10/1/2012	10/28/2012	Concluded	Barry Hansen	7/12/2012 1:01:58 PM
		Description: Coordinate with administrators and investigators from U. M. to complete research and maintain timely billings.
D		Measure erosion rates	3/2/2013	5/28/2013	Concluded	Barry Hansen	9/5/2012 8:01:48 AM
		Description: Chronic erosion of the shoreline of Flathead Lake is occurring to the detriment of water quality and important littoral habitat. The first step is the process to address this problem is the quantification of the rate of erosion and the association of those rates with specific site attributes, such as vegetation, substrate and fetch. We therefore are measuring beach profiles, wave energy, substrate size, prevailing wind intensity and direction, erosion and accretion rates, and lake elevations. Erosion rates are monitored at all completed restoration sites to evaluate the stability of the restored profile. In addition, erosion rates are measured in long term study sites such as East Bay, and in randomized locations to quantify lake-wide erosion rates and to correlate location with key parameters such as fetch and exposure. study sites such as in East Bay, and in rnadom locations to
E		Compare erosion rates at multiple erosion control sites	2/2/2013	5/28/2013	Concluded	Barry Hansen	7/12/2012 1:01:58 PM
		Description: Compare erosion rates throughout Flathead Lake at sites without erosion control measures, sites with "soft" control measures, and sites with "hard" control measures.
F		Coordinate with lakeshore landowners	10/1/2012	9/30/2013	Concluded	Barry Hansen	7/12/2012 1:01:59 PM
		Description: Inform and educate lakeshore landowners about natural solutions to lakeshore erosion and coordinate with them to implement those solutions rather than constructing concrete retaining walls.
