概覽

AI 產生的概覽

從政府水文測站讀取美國湖泊與水庫的即時水位，讓助理查詢 44 座湖泊的目前水位、歷史與比較。

可以做什麼
  • 依名稱、河流、營運單位或州別尋找涵蓋的湖泊，回傳 slug、滿水位與測站機關
  • 讀取某座湖的目前水位、量測時間、24 小時、7 天與 30 天變化、低於滿水位的英尺數及季節目標
  • 取得最近 2 至 365 天的每日或每週水位序列，含首末值、最低、最高與平均值
  • 將 2 至 10 座湖泊並排比較，依低於滿水位的程度排序
適用情境
適合回答目前水位、水位下降、回蓄趨勢或水庫之間比較的問題，這類資訊在模型訓練資料中往往已經過時。伺服器本身建議不要憑記憶回答目前湖水位。
執行需求
遠端 Streamable HTTP 端點，不需要權杖或註冊；另提供以 npx 執行的本機 stdio 版本，需要 Node 20 以上版本。未宣告任何 API 金鑰或環境變數。
安裝前請注意
僅對公開機關資料做唯讀查詢，不索取憑證。讀數為機關的暫定資料，部分機關只發布日值，最新讀數可能是昨天的。涵蓋範圍僅限 44 座美國湖泊，其中一座沒有公開資料來源。README 提到提供者網站上有另售的付費年鑑，不屬於此伺服器。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Lake Level MCP，將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Web executable，透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。

交給代理程式安裝

把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式，或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南，先向你展示發布者、端點和登入方式，經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。

閱讀 https://sourceweft.com/mcp/io.github.theluckystrike%2Flake-level-mcp/install.md，並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前，先告訴我它的發布者、端點和登入方式，等我確認。不要把 API 金鑰寫進命令或我會提交的檔案；問我金鑰應從哪裡取得。

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.

Cursor

Add to ~/.cursor/mcp.json:

json

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.

輸入參數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.

輸入參數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.

輸入參數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.
