Large Scale Lake Planning
The creation of the Long Lake management plan was initiated by the Long Lake Protection and Rehabilitation District to provide information to managers and citizens regarding the long-term management of Long Lake .. The data, results and conclusions from Phases I through IV of this project have been presented in detail in the document entitled Long Lake Management Plan, Phases I-IV: Lake Management Plan (Barr Engineering, 2001). A summary of Phases I-IV is presented in this report. Phases V and VI are presented here in detail for the first time. These final phases involve the establishment of a longterm water quality goal for Long Lake; the research and modeling of several management alternatives that would help the lake meet its goal, and the completion of a management plan for the lake.
The Long Lake Protection & Rehabilitation District has previously conducted a four phase comprehensive lake water quality monitoring, tributary monitoring, sociological survey, watershed evaluation, plant survey, and hydrologic and phosphorus budget study of Long Lake in Polk County. The Phase 1 through Phase 4 projects have provided data and analysis that will lead to the development of a comprehensive lake management plan.
The Long Lake District now will conduct concurrent Phase 5 and Phase 6 projects that will conclude in the production of a comprehensive lake management plan. Specific Phase 5 activities include; Establishing goals and computer modeling of watershed and in-lake management practices, and evaluating the lake's response(s) to determine management practices that result in goal achievement. Phase 6 of this on-going project will include preparation of the lake's management plan.
Specific deliverables for this Phase 5 grant project include:
* Report on the computer modeling and goal establishment activities.
The Department of Natural Resources will be provided with both a paper copy and an electronic copy of the final report. The project results will be disseminated to the public by newsletter(s), public meeting(s), and local newspaper articles.
Scope amendment no. 1, 02/11/2003: Scope amended to include collecitng additional in-lake sediment samples and analyzing and evaluating the nutrient release properties.
