Sentinel watersheds and lakes as focal points of long-term monitoring and research

USGS Objectives – Monitoring super-sentinel lakes

1. Continuous monitoring of physical and chemical parameters 1. Characterize habitat and populate bio-physical

models of lake metabolism1. Test prediction of published temperature/habitat

models2. Calibrate carbon-based lake metabolism model3. Estimate important flux rates

2. Methods – mobile data platforms; in-lake rate est.

1. Instrument rafts and thermistor buoys2. Sediment core incubations3. Algal bioassays

USGS Lake Monitoring Program

Continuous water quality monitoring raft

Continuous temperature data collection using temperature-logger chains at fixed locations

Sentinel watersheds and lakes as focal points of long-term monitoring and research

USGS Objectives – Monitoring super-sentinel lakes

2. Continuous monitoring of meteorological / physical parameters to populate bio-physical models of lake hydrology and physics

Sentinel watersheds as focal points of long-term monitoring and research

USGS Objectives – Monitoring watershed1. Monitoring of physical and chemical

parameters to characterize inflow and outflow from lakes1. Monitor water level to characterize water mass

balance

2. Monitor discharge at tributaries and outlets

3. Calculate loads and residence times for nutrients

2. Estimate ground-water contributions to water balance – thermal surveys, isotope studies, water balance calculation

3. Estimate landcover and landuse for tributary sub-watersheds and ungaged contributing zones using existing data

Linked watershed-lake biophysical models to forecast future habitat and water quality

Objectives:Comparison of statistical models of load / lake productivity models with dynamic, mechanistic models of productivity and habitat (bio-hydrology)

• Watershed models to estimate external loading – SWAT, HSPF, or ARC-HYDRO watershed model

• Lake models to estimate productivity, habitat and water quality (e.g., OECD; CE-QUAL-W2 or WASP)

• 3D lake modeling to estimate fine-scale habitat and trophic dynamics (carbon cycling; stoichiometry)– realistic food-web component for algal

dynamics and zooplankton grazing– Output adaptable for bio-energetics

models

Project Objectives – Outcomes

Meeting Project Objectives – • Coordinated monitoring of three super-sentinel

lakes (plus 1) – joint data-collection efforts by multiple partners– Multiple-year datasets– Strong inference into complex processes and functions

• Example: Shingobee lake, MN

• Data sets to test habitat model predictions; • Model system response to external forcing

– Calibrate and test bio-physical models for scenario modeling

• scenarios on landuse, climate and trophic dynamics / productivity

• bio-hydrology
