已验证Streamable HTTP可网页运行位置与生活数据与分析

概览

AI 生成的概览

从政府水文测站读取美国湖泊与水库的实时水位，让助手查询 44 座湖泊的当前水位、历史与对比。

可以做什么
  • 按名称、河流、运营方或州查找覆盖的湖泊，返回 slug、满库水位与测站机构
  • 读取某湖当前水位、测量时间、24 小时、7 天与 30 天变化、低于满库的英尺数及季节目标
  • 获取最近 2 至 365 天的每日或每周水位序列，含首末值、最低、最高与均值
  • 将 2 至 10 座湖泊并排对比，按低于满库的程度排序
适用场景
适合回答当前水位、水位下降、回蓄趋势或水库之间对比的问题，这类信息在模型训练数据中往往已过时。服务器本身建议不要凭记忆回答当前湖水位。
运行要求
远程 Streamable HTTP 端点，无需令牌或注册；另提供基于 npx 的本地 stdio 版本，需要 Node 20 或更高版本。未声明任何 API 密钥或环境变量。
安装前请注意
仅对公开机构数据做只读查询，不索取凭据。读数为机构的临时数据，部分机构只发布日值，最新读数可能是昨天的。覆盖范围仅限 44 座美国湖泊，其中一座没有公开数据源。README 提到提供方网站上有单独付费的年鉴，不属于本服务器。

README

lake-level-mcp

Live US lake and reservoir water levels for AI assistants, read at call time from USGS, USACE, CDEC, Reclamation and TWDB gauges.

This is a Model Context Protocol (MCP) server. It covers 44 lakes in 12 states, including Lake Mead, Lake Powell, Lake Travis, Shasta, Oroville, Folsom, Lake Lanier, Lake Texoma and Kentucky Lake. It needs no API key.

Tools

ToolWhat it returns
search_lakesCovered lakes by name, river, operator or state, with slug, full pool and gauge.
get_lake_levelCurrent elevation, measurement time, change over 24 hours, 7 days and 30 days, feet below full pool, the operator seasonal target where one is published, percent full where the agency publishes storage, gauge id and data URL.
get_lake_historyDaily or weekly elevation series for up to 365 days, with first, last, low, high and mean.
compare_lakes2 to 10 lakes side by side, ranked by feet below full pool. A lake whose gauge is down is reported, not fatal.

Every result has structured JSON, a one-paragraph summary, as_of, source (the agency URL) and more (the lake page on lakelevelnow.com).

What it knows that your model does not

  • Today's water level. Lakes move every hour and a model's training data is months old.
  • Which gauge to read for each lake. The bindings (USGS site and parameter, CDEC station, Reclamation RISE item, TWDB reservoir, USACE CWMS time series) are the verified set lakelevelnow.com uses.
  • Full-pool elevations and published seasonal guide curves (USACE, TVA, Alabama Power), so "8 ft low" can be read against the winter target, not only against summer full pool.
  • How to handle feed quirks: unpadded CDEC dates, CWMS loggers that stamp local time as UTC, USGS 15-minute data collapsed to one reading per day.

Install

Hosted (Claude.ai custom connector, ChatGPT developer mode)

Or run it locally over stdio:

claude mcp add lake-level -- npx -y lake-level-mcp

Claude Desktop

Add to claude_desktop_config.json:

json
{  "mcpServers": {    "lake-level": { "command": "npx", "args": ["-y", "lake-level-mcp"] }  }}

Cursor

Add to ~/.cursor/mcp.json:

json
{  "mcpServers": {    "lake-level": { "url": "https://lake-level-mcp.lipmichal.workers.dev/mcp" }  }}

VS Code

Add to .vscode/mcp.json:

json
{  "servers": {    "lake-level": { "type": "http", "url": "https://lake-level-mcp.lipmichal.workers.dev/mcp" }  }}

Node 20 or newer is needed for the local stdio version.

Example prompts

  • "What is the Lake Mead water level today, and how far below full pool is it?"
  • "Is Lake Lanier above or below its winter guide curve right now?"
  • "Show Lake Powell's level over the last year, weekly."
  • "Compare Shasta, Oroville and Folsom: which is fullest?"
  • "Which Texas lakes do you cover?"

Data sources

All public and keyless. Full list with fetch dates in DATA_SOURCES.md.

  • USGS Water Services, instantaneous and daily values (waterservices.usgs.gov)
  • California Department of Water Resources, CDEC (cdec.water.ca.gov)
  • U.S. Bureau of Reclamation RISE API (data.usbr.gov)
  • Texas Water Development Board, Water Data for Texas (waterdatafortexas.org)
  • U.S. Army Corps of Engineers CWMS Data API (cwms-data.usace.army.mil)

Upstream answers are cached for 15 minutes (current level) or 1 hour (history) to respect the agencies' services.

Limitations

  • 44 lakes, the same set as lakelevelnow.com. High Rock Lake (NC) has no public government feed and returns a clear error.
  • Readings are provisional agency data. CDEC, TWDB and Reclamation publish daily values, so their latest reading is usually yesterday's.
  • USGS keeps about 120 days of 15-minute data. For longer history the server uses USGS daily means where the site publishes them, and TWDB's daily record for Texas lakes. Some gauges return less than 365 days; the result says how many days it covers.
  • Percent full is shown only where the agency publishes storage (CDEC, Reclamation, TWDB).
  • When an agency service is down, the tool returns an error that names the agency and links the lake page, which keeps the last published reading.

More

Charts, boat ramp context and the paid Lake Level Almanac (decades of daily record and day-of-year normals per lake) are on lakelevelnow.com. The almanac covers 19 of these lakes: lakelevelnow.com/almanac.

search_lakes

Search US lakes and reservoirs

List the 44 US lakes and reservoirs this server reads live (Lake Mead, Lake Powell, Lake Travis, Shasta, Oroville, Lanier, Texoma, Kentucky Lake and more) by name, river, operator or state. Returns each slug, full-pool elevation, the gauge agency and the lakelevelnow.com page. Call with no arguments to list them all.

输入参数querystate

get_lake_level

Get current lake level

Current water surface elevation (ft above sea level) of a US lake or reservoir, read now from its government gauge (USGS, USACE CWMS, CDEC, Reclamation or TWDB). Returns the measurement time, change over 24 hours, 7 days and 30 days, feet below full pool, the operator seasonal target where one is published, percent full where the agency publishes storage, and the gauge id and data URL. Your training data cannot know today's level.

输入参数lake必填

get_lake_history

Get lake level history

Daily (or weekly) water elevation series for a US lake or reservoir over the last 2 to 365 days, from the same government gauge as get_lake_level, one reading per day. Includes first, last, low, high and mean with dates. Use it for trends, drawdown and refill questions.

输入参数dayslake必填step

compare_lakes

Compare lake levels

Current levels of 2 to 10 US lakes side by side, read live from their gauges: elevation, feet below full pool, percent full, seasonal target and 24 h / 7 day / 30 day change, ranked by distance below full pool. A lake whose gauge is down is reported with its error instead of failing the whole call.
