A WSB 178 East 9th Street, Suite 200 1 St. Paul, MN 55101 1 (651) 286-8450 April 19, 2018 Ms. Cassy Ordway, President Long Lake Waters Association PO BOX 195 Long Lake, MN 55356 Re: Proposal to Provide Obstruction Removal and Carp Management Services — Long Lake Long Lake Creek Subwatershed Partnership Dear Ms. Ordway: am pleased to offer this proposal to provide lake bottom obstruction removal, carp removal, and carp management services to the Long Lake Creek Subwatershed Partnership, which includes the City of Long Lake, City of Medina, City of Orono, Long Lake Waters Association, and the Minnehaha Creek Watershed District. Carp management is identified in the Long Lake Total Maximum Daily Load (TMDL), and other planning documents, as an implementation activity to improve water quality in Long Lake and the greater subwatershed. To address the issue of an overabundant carp population in Long Lake and the greater subwatershed, WSB will partner with JR Commercial Fish to: 1) Remove items that may be obstacles when netting Long Lake, 2) Quantify the carp population, 3) Track and identify carp aggregations, 4) Remove a portion of the carp population, 5) Complete ageing of a subsample of the carp population. This proposal combines two (2) previous proposals dated December 12, 2017 and March 1, 2018 and adds an ageing component as well as one additional fall electrofishing survey. SCOPE OF SERVICES This proposal provides a basic approach that blends data collection with project implementation. Discussion with commercial fishing crews, that would be tasked with carp removal operations, indicate that collecting data on carp abundance and location is critical to successful project implementation. Prior to beginning any field work, WSB staff will secure a MN DNR fisheries research permit. Anecdotal information suggests that carp biomass is elevated in Long Lake and the greater watershed. To definitively confirm this, we propose to complete both an electrofishing catch per unit effort (CPUE), and a mark -recapture population estimate. These activities can be completed simultaneously and will provide both project partners and the commercial fishing crews with an estimate of the amount of carp biomass in Long Lake. To develop the mark -recapture estimate, carp captured during the spring and fall electrofishing surveys will be fin clipped and released for recapture. Building a legacy — your legacy.
