Lake and Reservoir Source-Water Protection: From System Discovery to Verified Prevention
Move from source-to-tap fundamentals and system discovery through protection-area evidence, susceptibility monitoring, utility handoff, authorized prevention, implementation, maintenance, effectiveness, and controlled revision.

Finish with a field-ready draft, not a badge.
A versioned source-water system and authority map, safe concern route, assessment and provenance ledger, protection-area and susceptibility model, bounded monitoring package, protection program, contamination-handoff tabletop, implementation and maintenance record, and preregistered effectiveness and public-correction plan.
Bring the lake or reservoir name, any known utility or intake identity, current utility and authority contacts, access and security rules, available source-water assessments, watershed records, public-data queries, monitoring records, laboratory and custody procedures, emergency plans, and existing protection activities. Unknowns may remain explicitly unresolved.
Field route
Use an authored handoff; this is not an automatic recommendation or approval.
Open Lake and Reservoir Source-Water Protection, Monitoring, and Utility Handoff Record Document attributable states in Lake and Reservoir Source-Water Protection, Monitoring, and Utility Handoff Record before leaving Lake and Reservoir Source-Water Protection: From System Discovery to Verified Prevention.
Shared route boundary
This route does not determine tap safety, issue customer advice, authorize sampling, or direct intake or treatment operations.

Understand · 24 minutes Separate the source-to-tap evidence states
Distinguish lake source water, intake-zone water, raw water, treatment-process water, finished water, distribution water, and tap water before interpreting evidence.
Field exerciseLabel twelve hypothetical records by water state, source, time, method, authority, and prohibited inference.
CheckpointCan the team explain why a source-water result does not determine tap safety and a finished-water result does not establish lake condition?
Practice · 30 minutes Practice safe concern reporting and security control
Protect people, document an observation without naming a contaminant, route it, and protect intake and response information.
Field exerciseTabletop an odor report, an upstream sheen, and a security concern using observation-only and no-sample branches.
CheckpointDid every scenario avoid unsafe approach, improvised sampling, tap-safety claims, and exact public intake locations?
Document · 32 minutes Retrieve current assessment and source records
Preserve assessment versions and public-data provenance without treating portal silence as absence or compliance.
Field exerciseCreate a source ledger for DWMAPS, WQP, ATTAINS, How's My Waterway, USGS, state, Tribal, and utility records with query and scope limits.
CheckpointCan another reviewer reproduce each query and see what it cannot establish?
Understand · 38 minutes Delineate the source-water protection area
Build a versioned hydrologic model of lake, tributary, watershed, intake zone, and travel assumptions.
Field exerciseMap included, excluded, uncertain, seasonal, and event-dependent pathways with data sources and confidence.
CheckpointAre proximity, hydrologic connection, pathway, and travel time preserved as different evidence states?
Document · 34 minutes Inventory potential contaminant sources
Record potential source categories, evidence, currency, and gaps without asserting a current release, causation, violation, or culpability.
Field exerciseReconcile public layers, field knowledge, permits, utility records, and unknowns into a versioned inventory.
CheckpointDoes every record distinguish potential source, current operation, observed release, pathway, detection, and responsibility?
Decide · 40 minutes Evaluate source-pathway-receptor susceptibility
Prioritize evidence needs through transparent source, pathway, receptor, controls, uncertainty, and consequence dimensions.
Field exerciseScore three scenarios with documented evidence and sensitivity checks, including an unknown and a no-action follow-up branch.
CheckpointCould a reviewer reproduce the ranking without reading it as contamination or blame?
Measure · 46 minutes Design the monitoring evidence package
Assign baseline, sentinel, event, tributary, lake, depth, and intake-zone roles to one decision without a universal panel.
Field exerciseDraft stations, depths, timing, operating-state context, methods, reporting limits, QA, validation, security, and handoff rules.
CheckpointDoes the design state what a detection, screening result, and non-detect can and cannot support?
Measure · 38 minutes Use the existing custody and laboratory workflow
Keep authorization, collection, custody, laboratory receipt, validation, and source-result interpretation separately attributable.
Field exerciseTrace one observation-only event, one no-sample event, and one authorized sample from decision through validation.
CheckpointCan no-sample and existing-data-only branches close validly without fabricated custody or results?
Decide · 44 minutes Build the protection plan and partnerships
Connect governance, assessment, partnership, preventive alternatives, resources, authority gates, and revision.
Field exerciseWrite a responsibility matrix and alternatives register including no action, monitoring-only, prevention, and rejected options.
CheckpointAre eligibility, preference, funding, permit application, authorization, and implementation separate?
Practice · 45 minutes Run a contamination-handoff tabletop
Exercise upstream notification, utility, primacy, emergency, public-health, security, and public-communication handoffs without operating the intake or issuing advice.
Field exerciseRun a timed scenario from an upstream observation through case acknowledgement, evidence update, utility decision ownership, holding statement, correction, and closure.
CheckpointDid the source-water plan support, but not replace, the utility emergency-response plan?
Document · 36 minutes Verify implementation, operation, and maintenance
Preserve exact authorization, as-built evidence, deviations, acceptance, recurring maintenance, failure, and corrective action.
Field exerciseAudit one implemented practice against its authorization and lifecycle plan, leaving missing evidence unresolved.
CheckpointCan the record distinguish implementation from maintenance, acceptance, and effectiveness?
Document · 48 minutes Evaluate effectiveness, communicate securely, and revise
Preregister bounded endpoints, preserve uncertainty and adverse effects, control public release, and link corrections and supersession.
Field exerciseComplete the governed form with an existing-data-only branch, a no-action decision, one inconclusive endpoint, and an authority-approved generalized release.
CheckpointWould an independent reviewer distinguish effort, implementation, maintenance, effectiveness, public status, and durable protection?
